Fathers influence mothers’ breastfeeding decisions and experiences. Fathers’ perceptions of their roles as members of the breastfeeding family are likely important components of that influence. To explore that possibility, 21 involved fathers of breastfeeding babies volunteered to be interviewed regarding their fathering breastfed babies and their roles in the breastfeeding family. Fathers identified their unique roles as team members ensuring that their babies received the benefits of breastfeeding. A primary fathering role was that of supporting breastfeeding by becoming breastfeeding savvy, by using their knowledge to encourage and assist mothers in breastfeeding, by valuing the breastfeeding mothers, and by sharing housework and child care. Fathers’ nurturing roles involved fostering positive father-infant relationships in the face of limited opportunities to bond with their babies through feeding. The experiences of these fathers suggest the importance of assisting them to recognize their unique contributions to the nurture of their children as members of the breastfeeding team.

The American Academy of Pediatrics recommends exclusive breastfeeding until 6 months-of-age. The authors examined prevalence and risk factors for use of infant formulas, water, and teas at 4-6 weeks in Latino infants in the San Francisco Bay Area, a group at high risk for future obesity. They recruited a cohort of pregnant Latina women (N = 201). Infant dietary recall and postpartum depressive symptoms were assessed at 4-6 weeks. The authors found that 105 women (53.1%) were feeding infant formulas and 48 (25.4%) were supplementing with tea or water. Of those providing water or tea, 60.0% were providing daily supplementation. In multivariate analyses, risk for infant supplementation with water or tea was associated with postpartum depressive symptoms (relative risk, 1.8; 95% confidence interval, 1.1-3.0), cesarean delivery (relative risk, 1.9; 95% confidence interval, 1.3-2.9), and infant formula use (relative risk, 1.3; 95% confidence interval, 1.1-1.6). Early supplementation with water or teas and infant formulas should be discouraged in Latinos, given the high frequency observed in this population.

This research aims to explore, in qualitative terms, attitudes held by a sample of university-educated young men and women residing in New Brunswick and Nova Scotia about breastfeeding in public places. In sum, 20 women and 27 men between the ages of 18 and 23 participated in moderated single-sex focus groups that discussed breastfeeding, following a list of prepared questions and using photographs as discussion cues. Although participants uniformly stated that they desired their future children to be breastfed, 31 of 47 expressed restrictive attitudes toward exposure of the breast (eg, “should use washrooms,” “okay if discreet”) and breastfeeding in restaurants. Eight expressed positive unrestricted statements about breastfeeding in public spaces. Addressing widely held attitudes toward breastfeeding in public spaces, in addition to providing information about breastfeeding’s health benefits, may be helpful in campaigns promoting breastfeeding.

Managers’ attitudes influence female employees’ perceptions of workplace breastfeeding support. Five focus groups were conducted with managers in the state of Michigan (N = 25) to assess their attitudes toward supporting breastfeeding. All focus group discussions were recorded, transcribed verbatim, and analyzed for themes. Participants supported efforts by managers and companies to assist breastfeeding employees, but the extent of accommodations they supported varied. Most participants reported no company breastfeeding policy or were unaware of their company having one and showed mixed attitudes about needing a policy. Participants acknowledged the potential for lower productivity and coworker jealousy toward time for breastfeeding or expressing milk but believed that benefits of support included employee recruitment and retention. Participants demonstrated some understanding of breastfeeding benefits. They identified barriers and facilitators for breastfeeding support at both the organizational and individual levels. Results of this study will be used for instrument development to measure managers’ attitudes toward supporting breastfeeding.

The objective of the current study was to better understand how pregnant women and male partners conceptualize infant feeding and support for breastfeeding. Information was collected through 18 focus group interviews in 3 major US cities. There were 121 focus group participants of varying professions and income levels. Half were African American and half were Caucasian. Pregnant women and male partners had favorable attitudes toward breastfeeding, but did not articulate specific benefits to mothers or infants. Men expressed empathy for their partners’ pregnancies and deferred to their partners’ feeding decisions. Both groups disapproved of breastfeeding in public. Women voiced concerns about father-infant bonding more than men did. Both groups emphasized fathers’ support of the infant, but not of the mother. Educators and practitioners may wish to consider expectant couples’ perceptions of breastfeeding in public, knowledge of breastfeeding laws, and expectations of father-mother and father-infant relationships in their approach to breastfeeding promotion among expectant couples.

Immunocompetent cells in colostrum and mature breast milk (42 days after delivery) of 64 Chinese females of Han ethnic background were characterized. The total cell numbers in colostrum and mature breast milk were 593 ± 205 × 10⁶/L and 1.74 ± 0.97 × 10⁶/L, respectively. NK cell is the predominant lymphocyte subtype (12.69%). T cells in colostrum express CD40L and CD25 without stimulation, indicating memory T cells in nature. The CD45RA ⁺CD45RO⁺ subsets of CD4⁺ T cells are present in both colostrum and mature human milk. The percentage of NK cells and the absolute number of CD4⁺CD45RO⁺ T cells in colostrum of atopic mothers were significantly lower than those of mothers without atopy (P = .006 and .026, respectively). The absolute numbers of CD4 ⁺ T lymphocytes and their expression of CD40L were significantly reduced in breast milk of mothers who had undergone cesarean section versus vaginal delivery (P < .05), indicating that atopy and cesarean delivery are associated with the phenotypes of lymphocytes in colostrum.

While substantial evidence exists identifying risks factors associated with premature weaning from breastfeeding, there are no previously published definitions of patient acuity in the lactation field. This article defines evidence-based levels of lactation acuity based on maternal and infant characteristics. Patient acuity, matching severity of illness to intensity of care required, is an important determinant of patient safety and outcomes. It is often used as part of a patient classification system to determine staffing needs and acceptable workloads in health care settings. As acuity increases, more resources, including more skilled clinicians, are needed to provide optimal care. Developing an evidence-based definition of lactation acuity can help to standardize terminology, more effectively distribute health care staff resources, encourage research to verify the validity and reliability of lactation acuity, and potentially improve breastfeeding initiation and duration rates.

Breastfeeding represents the continued exposure of the infant to the maternal immune environment. Uterine, perinatal, and postnatal exposure to immune factors may contribute to an infant’s risk of developing immune-mediated disorders, including allergies. A PubMed search was conducted to review studies in humans and analyze concentrations of immune markers (TGF-β, IFN-γ, eotaxin, CCL5, CXCL10, TNF-α, MCP-1, IL-1β, IL-4, IL-5, IL-6, IL-8, IL-10, IL-12, IL-13, sCD14, sIgA, IgG4, IgM) found in maternal serum, amniotic fluid, cord serum, colostrum, transition and mature milk. Concentrations of immune markers showed large variations across samples and studies. Reports documented conflicting results. Small sample sizes, differences in population characteristics, inconsistent sample collection times, and various sample collection and measurement methods may have led to wide variations in the concentrations of immune markers. Studies analyzing the associations between immune markers in maternal fluids and infant allergies remain inconclusive because of gaps in knowledge and a lack of standardized methods.
