Abstract Objectives Achieving sensorimotor (SEM) milestones is one measure of early infant brain development promoted through higher docosahexaenoic acid (DHA) levels. Both breastmilk and formula contain DHA, with a global level of 0.32% in breastmilk and many formula brands. However, a 2017 study of Midwestern U.S. mothers found significantly lower breastmilk DHA levels. It was thus hypothesized that infants fed formula would have higher SEM scores. The objective of this study was to measure differences in SEM development between infants fed breastmilk, formula, or a combination in participants of the PediaTrac™ Project. PediaTrac is a web-based measure providing longitudinal, real time, multidomain data on infant and toddler growth and development at time periods corresponding to well child visits. Methods Using PediaTrac, data were collected from 548 caregiver-infant dyads across multiple Midwestern sites. Caregivers reported the primary nutrition source as breastfeeding, formula or combination. Their responses to gross and fine motor function questions were used to create a SEM composite, Percent of Maximum Possible (POMP) score at newborn (NB), 2-, 4- and 6-months. Data were analyzed via ANOVA and Tukey test using SPSS. Results Infants fed formula had statistically higher mean SEM scores at NB (M = 0.618Formula, M = 0.590Breast, p = 0.017), 2- (M = 0.706Formula, M = 0.680Breast, p = 0.006) and 6-months (M = 0.727Formula, M = 0.696Breast, p = 0.014) compared to breastfed infants. Mean SEM scores of combination fed infants were higher than breastfed infants at 2- (M = 0.701Combination, M = 0.680Breast, p = 0.184), 4- (M = 0.684Combination, M = 0.673Breast, p = 0.573) and 6-months (M = 0.704Combination, M = 0.696Breast, p = 0.895), despite no significant differences between scores. Conclusions Formula fed infants showed consistently higher SEM scores than breastfed infants in the first 6-months. These findings contradict previous research, indicating a need for further investigation into variables contributing to these discrepancies such as maternal breastmilk DHA concentrations, socioeconomic factors, site specific confounds, accuracy of parent reports of motor development, etc. Funding Sources Eunice Kennedy Shriver National Institute of Child Health & Human Development of the National Institutes of Health.

Brain development during the prenatal period is rapid and unparalleled by any other time during development. Biological systems undergoing rapid development are at higher risk for disorganizing influences. Therefore, certain prenatal exposures impact brain development, increasing risk for negative neurodevelopmental outcome. While prenatal exposures have been associated with cognitive and behavioral outcomes later in life, the underlying macroscopic brain pathways remain unclear. Here, we review studies investigating the association between prenatal exposures and infant brain development focusing on prenatal exposures via maternal physical health factors, maternal mental health factors, and maternal drug and medication use. Further, we discuss the need for studies to consider multiple prenatal exposures in parallel and suggest future directions for this body of research.

Illicit use of opioids is a global health crisis with major implications for women and children. Strategies for managing opioid use disorder (OUD) in pregnancy have been tested over the past 40 years, but studies have focused on maternal and pregnancy outcomes, with less attention given to long-term follow-up of exposed children. Here, we provide a narrative review of recent advances in the assessment and management of neonatal opioid withdrawal syndrome (NOWS), and we summarise evidence from multiple domains—neuroimaging, electrophysiology, visual development and function, neurodevelopment, behaviour, cognition and education—which suggests that prenatal opioid exposure modifies child development. Further studies are required to determine the optimal management of pregnant women with OUD and babies with NOWS. We identify knowledge gaps and suggest that future study designs should evaluate childhood outcomes, including infant brain development and long-term neurocognitive and visual function.

<b><i>Background:</i></b> While numerous studies have demonstrated maternal depression’s influence on infant brain development, few studies have examined the changes that occur as a consequence of co-occurring experiential factors that affect quality of mother and infant affectionate touch as well as infant temperament and neurophysiological systems. The aim of the study was to examine the interactive effects of maternal depression and breastfeeding on mother and infant affectionate touch and infant temperament and cortical maturation patterns across early development. <b><i>Methods:</i></b> 113 mothers and their infants participated when infants were 1 and 3 months of age. Questionnaires to assess maternal depressive symptoms, feeding, and temperament were completed. Tonic EEG patterns (asymmetry and left and right activity) were collected and the dyads were video-recorded during feeding to assess mother and infant affectionate touch patterns. <b><i>Results:</i></b> Data analysis showed that EEG activity and mother-infant affectionate touch differed as a function of mood and feeding method. Notably, only infants of depressed mothers that bottle-fed showed right frontal EEG asymmetry and attenuated change in the left frontal region across 3 months. Breastfeeding positively impacted affectionate touch behaviors and was associated with increased left and decreased right frontal EEG activation even for depressed groups. Furthermore, a model incorporating physiology, maternal depression, touch, temperament, and feeding indicated significant prediction for infant affectionate touch (with breastfeeding and affectively positive temperament demonstrating the strongest prediction). <b><i>Con­clusion:</i></b> The findings suggest that breastfeeding and the infant’s positive temperament influence mother-infant affectionate touch patterns and result in neuroprotective outcomes for infants, even those exposed to maternal depression within early development.

AbstractNearly 1 in 5 children in the United States lives in a household whose income is below the official federal poverty line, and more than 40% of children live in poor or near-poor households. Research on the effects of poverty on children's development has been a focus of study for many decades and is now increasing as we accumulate more evidence about the implications of poverty. The American Academy of Pediatrics recently added “Poverty and Child Health” to its Agenda for Children to recognize what has now been established as broad and enduring effects of poverty on child development. A recent addition to the field has been the application of neuroscience-based methods. Various techniques including neuroimaging, neuroendocrinology, cognitive psychophysiology, and epigenetics are beginning to document ways in which early experiences of living in poverty affect infant brain development. We discuss whether there are truly worthwhile reasons for adding neuroscience and related biological methods to study child poverty, and how might these perspectives help guide developmentally based and targeted interventions and policies for these children and their families.

While parents have long received guidance on how to raise children, a relatively new element of this involves explicit references to infant brain development, drawing on brain scans and neuroscientific knowledge. Sometimes called ‘brain-based parenting’, this has been criticised from within sociological and policy circles alike. However, the engagement of parents themselves with neuroscientific concepts is far less researched. Drawing on 22 interviews with parents/carers of children (mostly aged 0–7) living in Scotland, this article examines how they account for their (non-)use of concepts and understandings relating to neuroscience. Three normative tropes were salient: information about children’s processing speed, evidence about deprived Romanian orphans in the 1990s, and ideas relating to whether or not children should ‘self-settle’ when falling asleep. We interrogate how parents reflexively weigh and judge such understandings and ideas. In some cases, neuroscientific knowledge was enrolled by parents in ways that supported biologically reductionist models of childhood agency. This reductionism commonly had generative effects, enjoining new care practices and producing particular parent and infant subjectivities. Notably, parents do not uncritically adopt or accept (sometimes reductionist) neurobiological and/or psychological knowledge; rather, they reflect on whether and when it is applicable to and relevant for raising their children. Thus, our respondents draw on everyday epistemologies of parenting to negotiate brain-based understandings of infant development and behaviour, and invest meaning in these in ways that cannot be fully anticipated (or appreciated) within straightforward celebrations or critiques of the content of parenting programmes drawing on neuropsychological ideas.

The neurocognitive development of infants can be positively associated with breastfeeding exclusivity and duration. Differences in dietary lipid quality between human milk and infant milk formula may contribute to this effect. In this review, we describe some of the known differences between human milk and infant milk formula in lipid quality, including fatty acid composition, complex lipids in the milk fat globule membrane as well as the physical properties of lipids and lipid globules. We describe some of the underlying mechanism by which these aspects of lipid quality are thought to modulate infant brain development such as differences in the supply and/or the bioavailability of lipids, lipid bound components and peripheral organ derived neurodevelopmental signals to the infant brain after ingestion and on longer term.
