Longitudinal Prospective Study of Maternal and Child Nutrition in Arkansas

The investigators want to learn how women's diets may impact breastfeeding outcomes. This study will help the investigators learn more about how diet and social factors like food access may impact mothers' health, breastfeeding, and their baby's health. Participants will attend a visit before birth, then 11 visits as their baby grows up. All visits will be remote using RedCap, phone or video call, text messaging or any other communication modalities of preference to the participant. The investigators will ask for personal information about participants' family, home, and finances, health literacy, medical history, current medications, pregnancy complications, mental health (depression, quality of life), confidence in breastfeeding, eating habits, and plan to feed their baby. After childbirth, the investigators will ask about participants' delivery and child's health, and request access to their child's medical records. Across all visits, the investigators will ask participants to measure their weight, height, blood pressure, activity and sleep, and child's length; the investigators will also ask them to ship urine, stool, and breast milk samples. The investigators will obtain a 24-hour feeding log for the child, as well as a log of what the mother ate and drank over 24 hours.
