Mothers will be eligible for consent if they are a patient in the Duke University Hospital Labor & Delivery department and meet all eligibility criteria. Potential mothers will be approached about the study before delivery or within 72 hours after delivery. 150 mother-VLBW infant pairs, a total of 300 participants, will be recruited for the final sample size of 120 pairs. English or Spanish speaking mothers may participate. If the mother is between 15-17 years of age, a minor mother consent will be used. If the mother is Spanish speaking, a Spanish short form consent will be used with a Spanish interpreter. If the mother is pre-consented, the infant may or may not be enrolled at delivery. The infant could be excluded if he/she is delivered at a gestation or weight that is outside of study limits, or if she/he has a severe health problem/congenital anomaly detected at birth.
