Breastfeeding is analogous to pregnancy as an experience, in its exclusiveness to women, and in its cost and the effects it has on equitable share of labor. Therefore, the history of formula feeding provides useful insights into the future of full ectogenesis, which could evolve into a more severe version of what formula feeding is today: simplify life for some women and provide couples with a more equitable share of work at the cost of stigma, guilt (...) and a daily diet of studies purporting to show the benefits of natural pregnancy. Making pregnancy an optional route to motherhood would make women's life trajectory more similar to men's and thus put pressure on women to compete with men on the ground shaped by men's preferences. Despite being a treasured experience of many women today, bearing children could become the luxury of the few, the province of the very poor and a choice working women will pay a high price for as women who choose pregnancy become stigmatized as self-indulgent or unprofessional and penalized for it in the workplace. At the same time, scarce societal resources that could be used to support pregnant women and working mothers would instead be directed toward proving to women or even forcing them to gestate children "the right way." While not necessarily threatening on its own, when added to formula feeding, IVF, stem-cell produced ova and sex robots, full ectogenesis could diminish men's stake in women's wellbeing and even existence.

The debate over how to best guide HIV-infected mothers in resource-poor settings on infant feeding is more than two decades old. Globally, breastfeeding is responsible for approximately 300,000 HIV infections per year, while at the same time, UNICEF estimates that not breastfeeding (formula feeding with contaminated water) is responsible for 1.5 million child deaths per year. The largest burden of these infections and deaths occur in Sub-Saharan Africa. Using this region as an example of the burden faced (...) more generally in other resource-poor settings, we contrast the evolution of the clinical standard of care for infant feeding with HIV-infected mothers in high-income countries to the current international clinical guidelines for HIV-infected mothers and infant feeding in resource-poor settings. While the international guidelines of exclusive breastfeeding for a 6-month period seem to offer the least-worst strategy for reducing mother-to-child transmission of HIV during infancy while conferring some immunity through breastfeeding post-6 months, we argue that the impact of the policy on mothers and healthcare workers on the ground is not well understood. The harm reduction approach on the level of health policy translates into a complicated, painful moral dilemma for HIV-positive mothers and those offering them guidance on infant feeding. We argue that the underlying socio-economic disparities that continue to fuel the need for a harm reduction policy on infant feeding and the harm to women and children justify: (1) that higher priority be given to solving the infant feeding dilemma with improved data on safe feeding alternatives, and (2) support of innovative, community-driven solutions that address the particular economic and cultural challenges that continue to result in HIV-transmission to children within these communities.

This article theorises a group of mothers’ experiences of shame as a result of feeding infant formula to their children. Drawing on interviews with formula and breastfeeding mothers, the author brings together insights from scholarship on shame, feminist scholarship on reproductive labour and the Marxist notion of estranged labour to demonstrate that shame causes the formula-feeding mothers in this study, who initially wanted to breastfeed, to be estranged in their labour as mothers. The article addresses (...) a gap in qualitative infant-feeding scholarship, which focuses primarily on breastfeeding. It provides an empathic account framing breastfeeding and formula-feeding mothers as potential allies against ‘controlling images’ of motherhood who face different facets of the same pressure to fulfil idealised roles. Both scholarly work on reproductive labour, and public programmes supporting new mothers, should account more seriously for the experiences of formula feeding mothers. (shrink)

Breastfeeding advocates have criticised the phrase ‘breast is best’ as mistakenly representing breastfeeding as a departure from the norm rather than the default for infant feeding. Breastfeeding mothers have an interest in representing breastfeeding as the default, for example, to counteract criticism of breastfeeding outside the home. This connects to an increasing trend to frame feeding babies formula as harmful, which can be seen in research papers, public policy and information presented to parents and prospective parents. Whether (...) we frame infant-feeding decisions in terms of harming or benefit, protection or risk matters because these distinctions are generally morally significant and thus holding that those who decide to use formula ‘harm’, ‘risk harm’ to their babies or describing formula feeding as ‘dangerous’ is likely to contribute to guilt associated with formula feeding and thus to undermine the well-being of vulnerable women. It may undermine attempts to improve breastfeeding rates by leading women to reject information about health outcomes surrounding infant-feeding decisions. However, these distinctions do not apply easily to infant-feeding decisions, in part because of difficulties in determining whether we should treat breastfeeding as the normative baseline for infant feeding. I show that neither the descriptive ‘facts of the matter’ nor moral or pragmatic considerations provide an easy answer before discussing how to respond to these considerations. (shrink)

Breastfeeding advocates and global health agencies have been sounding alarms about the dangers of digital marketing practices of the formula-feeding industry. This study comprised a feminist discourse analysis of materials produced (blog, social media posts, comments) in a paid partnership between baby formula brand Enfamil and an influencer, Marilou Bourdon from Trois fois par jour. Our analysis reveals a sophisticated marketing campaign that co-opts feminist critiques of breastfeeding promotion discourse while carefully avoiding explicitly violating the International Code (...) of Marketing of Breast-milk Substitutes. Underlying this campaign is a rhetoric reliant on pathos to assuage maternal guilt and shame for feeding formula. (shrink)

In a recent article, Fiona Woollard draws attention to a number of problems, both theoretical and pragmatic, with current discourse around infant feeding. References both to the ‘benefits of breastfeeding’ and ‘harms of formula’ are problematic, since there is no obvious baseline of comparison against which to make these evaluations. Further, she highlights the pragmatic consequences of these linguistic choices. Saying that formula feeding harms babies, for instance, is likely to exacerbate feelings of guilt and shame (...) felt by many mothers who use formula, for various reasons. Since I agree with much that Woollard says, this response is mostly sympathetic, but I wish to draw attention to one point that is largely missing from her analysis. The pragmatic effect of an utterance depends significantly on who is speaking, to whom, and in what context. Thus, we might differentiate between what it is appropriate to say in a professional context, such as an academic journal, from what one might say in a policy document or to a new mother. While we should always be careful about the language that we use, we need not assume that the same language is appropriate in all contexts nor that equal care is always required. (shrink)

Breastfeeding and human milk are the normative standards for infant feeding and nutrition. Given the documented short- and long-term medical and neurodevelopment advantages of breastfeeding, infant nutrition should be considered a public health issue and not only a lifestyle choice.In a letter sent out to 2600 hospitals across the country they [Public Citizen] demand that healthcare facilities “immediately discontinue the distribution of commercial infant formula manufacturer discharge bags,” claiming it undermines women’s success at breastfeeding.

An evolutionarily informed perspective on parent-infant sleep contact challenges recommendations regarding appropriate parent-infant sleep practices based on large epidemiological studies. In this study regularly bed-sharing parents and infants participated in an in-home video study of bed-sharing behavior. Ten formula-feeding and ten breast-feeding families were filmed for 3 nights for 8 hours per night. For breast-fed infants, mother-infant orientation, sleep position, frequency of feeding, arousal, and synchronous arousal were all consistent with previous sleep-lab studies of mother-infant bed-sharing (...) behavior, but significant differences were found between formula and breast-fed infants. While breast-feeding mothers shared a bed with their infants in a characteristic manner that provided several safety benefits, formula-feeding mothers shared a bed in a more variable manner with consequences for infant safety. Paternal bed-sharing behavior introduced further variability. Epidemiological case-control studies examining bed-sharing risks and benefits do not normally control for behavioral variables that an evolutionary viewpoint would deem crucial. This study demonstrates how parental behavior affects the bed-sharing experience and indicates that cases and controls in epidemiological studies should be matched for behavioral, as well as sociodemographic, variables.

In this paper, we provide a new framework for understanding infant-feeding-related maternal guilt and shame, placing these in the context of feminist theoretical and psychological accounts of the emotions of self-assessment. Whereas breastfeeding advocacy has been critiqued for its perceived role in inducing maternal guilt, we argue that the emotion women often feel surrounding infant feeding may be better conceptualized as shame in its tendency to involve a negative self-assessment—a failure to achieve an idealized notion of good motherhood. (...) Further, we suggest, both formula-feeding and breastfeeding mothers experience shame: the former report feeling that they fail to live up to ideals of womanhood and motherhood, and the latter transgress cultural expectations regarding feminine modesty. The problem, then, is the degree to which mothers are vulnerable to shame generally, regardless of infant feeding practices. As an emotion that is less adaptive and potentially more damaging than guilt, shame ought to be the focus of resistance for both feminists and breastfeeding advocates, who need to work in conjunction with women to oppose this shame by assisting them in constructing their own ideals of good motherhood that incorporate a sense of self-concern.

This article is a discussion of the recently emerging critique of pro‐breastfeeding discourses in academic literature, and what this means for midwives and other professionals who find themselves promoting breastfeeding because of professional expectations or indeed workplace policies. Various strands in the debate are explored, starting with dominant and familiar ‘evidence’ and descriptions of breastfeeding and breastmilk that are carried through to international policies that advocate breast over formula feeding. We then consider evidence predominantly from social science literature (...) that has found some women's experiences of infant feeding to be at variance with the dominant pro‐breastfeeding ideology. We argue that midwives and others delivering maternity care are the means to deliver the policy aspirations contained in the World Health Organization (WHO, 2018) Baby Friendly Hospital Initiative document that makes selective positive claims about breastfeeding without adequately considering its potential drawbacks. We conclude that although the benefits of breastfeeding tend to be exaggerated in promotional material, on balance the weight of evidence still favours breast over formula feeding. We challenge the charge that breastfeeding jeopardises women's financial position by arguing that it is not breastfeeding per se that impacts negatively on women's economic prospects, but rather the way in which society is socially organised.

In lieu of an abstract, here is a brief excerpt of the content:94 Feminist Studies 47, no. 1. © 2021 by Feminist Studies, Inc. Jennifer C. Nash Black Lactation Aesthetics: Remaking the Natural in Lakisha Cohill’s Photographs In her 1992 essay “Selling Hot Pussy,” bell hooks recounts entering a “late night dessert place” with a group of colleagues who all began to laugh at a shelf of “gigantic chocolate breasts complete with nipples— huge edible tits.”1 For hooks, the chocolate Black (...) breasts are mammy imagery, a “displaced longing for a racist past when the bodies of black women were a commodity, available to anyone white who could pay the price.”2 For her white colleagues, the chocolate breasts are simply comical. Her colleagues’ response—their willingness to consume, laugh, and ignore racial, gendered, sexual violence—constitutes the racialized visual marketplace that hooks’s essay seeks to both describe and dismantle. The chocolate breasts become a rhetorical point of entry into hooks’s critical engagement with a visual marketplace where Black female bodies are delectable and disposable objects. hooks’s analysis has become part of a canon of Black feminist work exploring how Black breasts get taken up as signs of pathology, “excess flesh,” sexual deviance, hypersexuality, and alterity.3 From histories of the so-called Hottentot Venus and the preoccupation with her breasts, buttocks, and genitalia—including 1. bell hooks, “Selling Hot Pussy,” Black Looks: Race and Representation (Boston: South End Press, 1992), 61. 2. hooks, 61–62. 3.

In this imaginary, Black breasts provide nutrition only when recruited as white property, with their nurturance capacity oriented toward white health and futurity. We might understand the cultural inability to interpret Black breasts as nurturing Black life as part of what Andrea Freeman describes as the “unmothering” of Black women, the unseeing of Black maternity except to elevate it as a symbol of brokenness or pathology.6 But in recent years, as I argue in my forthcoming book Birthing Black Mothers, Black breasts have entered the US cultural imagination anew. Black breasts are increasingly viewed as in need of support through seemingly benign state interventions to encourage Black breastfeeding. Indeed, Black breasts are recruited by an array of actors who often find themselves strangely aligned to champion Black breastfeeding —including NGOs, public health campaigns, and reproductive justice efforts spearheaded by Black feminists—precisely because Black breastfeeding is thought to perform urgent political, emotional, and 4.

Among the most harrowing visuals of Britain’s ongoing ‘cost of living crisis’ are the security tags that began to appear on cheese, butter, chicken, sweets and infant formula milk in 2022. A week’s worth of formula milk—the sole or main food of the vast majority of infants for the first 6 months of life—now costs between £9.39 and £15.95.1 Low-income households are entitled to a ‘Healthy Start’ welfare payment, intended to avert malnutrition among the poorest children, but the (...) weekly allowance is just £8.50.2 There are reports of parents watering down formula, skipping or limiting feeds and initiating early weaning, all of which jeopardise the health of infants, with potentially lifelong consequences.3 No determinant of health is more critical than food. A 2019 study found that diet is the most significant risk factor for non-communicable disease, and that one in five deaths globally could be prevented by improving nutrition.4 Globally, 1 in 10 people cannot meet their daily energy needs,1 and the proportion of undernourished people is rising.5 In more than 50 countries, most of them in Africa, over a quarter of children are stunted or wasted due to undernourishment, with long-term effects on their cognitive and physical development. These are not problems of absolute scarcity; enough food is produced globally to feed ten billion people.6 In the UK, there is, at any given moment, sufficient food on supermarket shelves to meet the calorie and nutrient needs of the population. Yet the equivalent of nearly 200 million meals a year are discarded,7 while almost a quarter …. (shrink)

To date, our knowledge of Rift Valley fever disease spread and maintenance is still limited, as flooding, humid weather and presence of biting insects such as mosquitoes, have not completely explained RVF outbreaks. We propose a model that includes livestock, mosquitoes and ticks compartments structured according to their questing and feeding behaviour in order to study the possible role of ticks on the dynamics of RVF. To quantify disease transmission at the initial stage of the epidemic, we derive an (...) explicit formula of the basic reproductive number, $$R_0$$ R 0. Using the concept of Metzler matrix, we state necessary conditions for global asymptotic stability of the disease-free equilibrium. Results suggest that although host-ticks interactions may serve as disease reservoirs or disease amplifiers, the Aedes reproductive number should be kept under unity if disease post-epizootics activities are to be controlled. Results of both local and global sensitivity analysis of selected model parameters indicate that $$R_0$$ R 0 is more sensitive to the ticks attachment and detachment rates, probability of transmission from ticks to host and from host to ticks, length of infection in livestock and ticks death rate. Furthermore, when comparing the mean value of $$R_0$$ R 0 with that from previous studies which did not include ticks we found that our $$R_0$$ R 0 is very much larger resulting in an increase in the exponential phase of an outbreak. These findings suggest that if ticks are capable of transmitting the virus, they may be contributing to disease outbreaks and endemicity. (shrink)

Health institutions recommend that young infants be exclusively breastfed on demand, and it is widely held that parents who can breastfeed have an obligation to do so. This has been challenged in recent philosophical work, especially by Fiona Woollard. Woollard’s work critically engages with two distinct views of parental obligation that might ground such an obligation—based on maximal benefit and avoidance of significant harm—to reject an obligation to breastfeed. While agreeing with Woollard’s substantive conclusion, this paper (drawing on philosophical discussion (...) of the ‘right to rear’) argues that there are several more moderate views of parental obligation which might also be thought to ground parental obligation. We first show that an obligation to breastfeed might result not from a general obligation to maximally benefit one’s child, but from what we call ‘choice-specific’ obligations to maximise benefit within particular activities. We then develop this idea through two views of parental obligation—the Dual Interest view, and the Best Custodian view—to ground an obligation to exclusively breastfeed on demand, before showing how both these more moderate views fail. Finally, we argue that not only is there no general obligation to breastfeed children, but that it is often morally right not to do so. Since much advice from health institutions on this issue implies that exclusive breastfeeding on demand is the best option for all families, our argument drives the feeding debate forward by showing that this advice often misrepresents parents’ moral obligations in potentially harmful ways.

Food sharing may be used for mate attraction, sexual access, or mate retention in humans, as in many other species. Adult humans tend to perceive more intimacy in a couple if feeding is observed, but the increased perceived intimacy may be due to resource provisioning rather than feeding per se. To address this issue, 210 university students (66 male) watched five short videos, each showing a different mixed-sex pair of adults dining together and including feeding or simple (...) provisioning or no food sharing. A survey concerning attraction and intimacy in the dyad was completed after each video. Both provisioning and feeding produced higher ratings of “Involvement,” with feeding producing the highest ratings. Similarly, the perceived attraction of each actor to the other was lowest when no food sharing was shown and highest when feeding was displayed. These findings are consistent with a view of feeding as a courtship display in humans. (shrink)

Highlights: -/- • Breastfeeding and breastfeeding support can contribute to mitigating climate change. • Achieving global nutrition targets will save more emissions than fuel-switching. • Breastfeeding support programmes support a just transition. • This work can support the expansion of mitigation options in energy system models. -/- Abstract: -/- Renewable gas has been proposed as a solution to decarbonise industrial processes, specifically heat demand. As part of this effort, the breast-milk substitutes industry is proposing to use renewable gas as a (...) substitute for fossil natural gas. However, decarbonising the industrial processing of breast-milk substitutes can increase social license for these products, potentially undermining breastfeeding. World Health Organisation nutrition targets aim to increase exclusive breastfeeding to at least 50% globally by 2025 to improve maternal, infant, and young child health and nutrition. This target will have implications for the energy transition. A weakness of existing energy models is that demands for end-use products such as breast-milk substitutes are typically not considered explicitly. This paper develops an analytical framework for explicitly representing infant feeding methods in energy systems models. We compare the emissions saved in Ireland from decarbonising the industrial processing of breast-milk substitutes with renewable gas with the emissions saved by an increase in exclusive breastfeeding to 50% in both Ireland and a key export market, China. We demonstrate that the emissions saved from achieving the minimum global breastfeeding target are greater than when renewable gas is used to displace natural gas in the production of breast-milk substitutes in Ireland. We discuss the decarbonisation of breast-milk substitutes in relation to the principle of justice as non-maleficence, a principle based on the commitment to avoid harm, a novel application of a principle of justice. We conclude that breastfeeding support can be considered a demand-side measure for mitigating climate change by reducing the demand for energy services to produce breast-milk substitutes. A key recommendation is to position breastfeeding support as both a public health and a climate justice issue that is relevant for a just transition. The framework developed for this paper could be applied to support the inclusion of a wider range of mitigation options with social justice outcomes in energy system models. [Open access]. (shrink)

Zangwill (“Our Moral Duty to Eat Meat”, “If you care about animals, you should eat them”) has argued that we have a duty to eat meat. In this paper I first show that Zangwill’s essays contain two distinct conclusions: (1) a rather weak thesis that his argument is officially supposed to establish, and (2) a much stronger, advertised thesis that his argument is not officially supposed to establish, but on whose basis he gives concrete recommendations for action and launches polemic (...) attacks on vegans, animal rights activists, and others. Consequently, I argue that Zangwill is likely culpable of some combination of epistemic failure, objectionable carnist activism, and trolling. In the second part of this paper I rebut Zangwill’s argument proper. I conclude by identifying some important issues in the vicinity concerning the suffering of wildlife and population ethics generalized to both human and non-human animals. (shrink)

Phase I clinical trials are the first stage of testing new pharmaceuticals in humans. The majority of these studies are conducted under controlled, inpatient conditions using healthy volunteers who are paid for their participation. This article draws on an ethnographic study of six phase I clinics in the United States, including 268 semistructured interviews with research staff and healthy volunteers. In it, I argue that an institutional banalization of risk structures the perceptions of research staff and healthy volunteers participating in (...) the studies. For research staff, there are three mechanisms by which risk becomes banal: a perceived homogeneity of studies, Fordist work regimes, and data-centric discourse. For healthy volunteers, repeat study participation contributes to the institutional banalization of risk both through the process of desensitization to risk and the formation of trust in the clinics. I argue that the institutional banalization of risk also renders invisible ethical concerns about exploitation of underprivileged groups in pharmaceutical research. (shrink)

The conceptual and investigative tools for the analysis of social behavior can be expanded by integrating biological theory, control systems theory, and Pavlovian conditioning. Biological theory has focused on the costs and benefits of social behavior from ecological and evolutionary perspectives. In contrast, control systems theory is concerned with how machines achieve a particular goal or purpose. The accurate operation of a system often requires feed-forward mechanisms that adjust system performance in anticipation of future inputs. Pavlovian conditioning is ideally suited (...) to subserve this function in behavioral systems. Pavlovian mechanisms have been demonstrated in various aspects of sexual behavior, maternal lactation, and infant suckling. Pavlovian conditioning of agonistic behavior has been also reported, and Pavlovian processes may likewise be involved in social play and social grooming. Several further lines of evidence indicate that Pavlovian conditioning can increase the efficiency and effectiveness of social interactions, thereby improving their cost/benefit ratio. We extend Pavlovian concepts beyond the traditional domain of discrete secretory and other physiological reflexes to complex real-world behavioral interactions and apply abstract laboratory analyses of the mechanisms of associative learning to the daily challenges animals face as they interact with one another in their natural environments. Key Words: aggression; biological theory; control theory; feed-forward mechanisms; learning theory; nursing and lactation; Pavlovian conditioning; sexual behavior; social behavior; social grooming; social play.

Using Demographic and Health Survey datasets from Ghana and Nigeria, this study examined whether the protective effects of breast-feeding are greatest where the poorest sanitation conditions prevail. It was found that mixed-fed infants aged between 0 and 11 months tend to have a higher risk of diarrhoea than fully breast-fed children, while the risk of diarrhoea among weaned infants is twice that of mixed-fed infants. The probit regression models employed in the analysis were used to predict the probability of (...) diarrhoea associated with each breast-feeding pattern for both ‘poor’ and ‘good’ sanitation areas. It was found that the risk of diarrhoea among mixed-fed infants in the poor sanitation areas tends to be high while the same risk among fully breast-fed infants tends to be minimal. In essence, the health risks of mixed feeding are real, particularly for infants aged less than 7 months, and are even worse for those weaned before 6 months of age. (shrink)

This paper explores the consequences of the theoretical forward activation enzymatic pathway A 0 A 1 A 2 A 3 where E 1 convents A 0 to A 1, E 2 converts A 1 to A 2 and E 3 converts A 2 to A 3. A 0, which is environmentally determined, also serves to activate (or modulate) the activity of E 3 in such a way as to keep the concentration of A 2 ([A 2]) constant at a particular (...) set-point value. For mathematical simplicity, first order rate kinetics are used where k 1, k 2 and k 3 are the rate constants for E 1, E 2, and E 3 respectively. It is shown that if k 3 is modulated appropriately so as keep [A 2] at the setpoint value with a changing upstream [A 0], then the modulation of k 3 must be anticipatory of the dynamics of the biochemical pathway. In other words, the rate of change of k 3, will be a function of [A 0], k 1, k 2, k 3, and the set-point value of [A 2]. If the modulation of k 3 does not perfectly model (anticipate) the reaction pathway of which it is a part, then the actual [A 2] will deviate from the set-point value. This type of anticipatory feed-forward activation may represent an important aspect of biological organization. (shrink)

Current, prevalent models of the food system, including complex-adaptive systems theories and commodity-as-relation thinking, have usefully analyzed the food system in terms of its elements and relationships, confronting persistent questions about a system’s identity and leverage points for change. Here, inspired by Heldke’s analysis, we argue for another approach to the “system-ness” of food that carries those key questions forward. Drawing on Niklas Luhmann’s systems theory, we propose a model of the food system defined by the relational process of (...) class='Hi'>feeding itself; that is, the food system is made of feeding and only feeding, and system structures are produced by the coupling of that process to its various contexts. We argue that this approach moves us away from understandings of the food system that take structures and relations as given, and sees them instead as contingent, thereby helping to identify leverage points for food system change. The new approach we describe also prompts us as critical agrifood scholars to be constantly reflexive about how our analyses are shaped by our own assumptions and subjectivities. (shrink)

Dubreuil (Biol Phil 25:53–73, 2010b , this journal) argues that modern-like cognitive abilities for inhibitory control and goal maintenance most likely evolved in Homo heidelbergensis , much before the evolution of oft-cited modern traits, such as symbolism and art. Dubreuil’s argument proceeds in two steps. First, he identifies two behavioral traits that are supposed to be indicative of the presence of a capacity for inhibition and goal maintenance: cooperative feeding and cooperative breeding. Next, he tries to show that these (...) behavioral traits most likely emerged in Homo heidelbergensis . In this paper, I show that neither of these steps are warranted in light of current scientific evidence, and thus, that the evolutionary background of human executive functions, such as inhibition and goal maintenance, remains obscure. Nonetheless, I suggest that cooperative breeding might mark a crucial step in the evolution of our species: its early emergence in Homo erectus might have favored a social intelligence that was required to get modernity really off the ground in Homo sapiens.

The effects of breast-feeding and supplementation practices on recent diarrhoea occurrence and stunted growth are modelled using logistic regression techniques. Data from the Demographic and Health Survey of Bolivia, 1989, show that, among children aged 3-36 months at the date of interview, the benefits of breast-feeding to child health were most pronounced among children living in rural poverty. Reduced breast-feeding among these children increased the likelihood of diarrhoea and stunted growth. In addition, the introduction of solid foods (...) to currently lactating infants negatively influenced child health. (shrink)

The paper makes two contributions. Firstly, the model provides a formal account of the variables that are built into FUL: agents, maxims, intentions, actions, and outcomes. This establishes a (...) clear benchmark for understanding how the mechanics of FUL actually work. Secondly, the analysis of the resulting framework sheds new light on discussions about the implications of FUL. On the basis of this, we suggest a move to “comprehensive Kantianism’, which is the application of FUL to systems of maxims rather than to isolated maxims. (shrink)

Medical Officer of Health reports for London boroughs, 1900–19, are analysed to determine the incidence of neonatal breast-feeding, duration of lactation, reasons for early supplementation and premature weaning, and their relationship with infant mortality. In a sample of 222,989 infants, breast-feeding rates were very high. Over 90% were breast-fed in the first month, almost 80% at 3 months, and over 70% at 6 months. The poorest boroughs had the highest rates of neonatal breast-feeding, but also a higher (...) incidence of early supplementation and premature weaning. There was a significant positive correlation between breast-feeding and infant mortality due to poor maternal diet and health, poor nutritional quality of supplementary and substitute foods, and the use of an unhygienic feeding bottle. Energetic campaigns to counteract these problems probably contributed to the fall of infant mortality in this period. (shrink)
