This nutritional intervention study involves assessments in both the mother and her infant. The mother will be asked to complete self-report questionnaires and to undergo a brief cognitive assessment. If the mother is not breastfeeding, a study product will be provided and will be consumed by the infant daily up to 12 months of life. The study also involves magnetic resonance imaging (MRI) brain scans of the infant's brain while asleep as well as evaluations of general cognitive and social-emotional development.
