Title: The Intervention Nurses Start Infants Growing on Healthy Trajectories (INSIGHT) Study
Brief Summary: This study will test an intervention program designed to provide developmentally appropriate guidance to parents of infants on responsive parenting and healthy lifestyle to see if that intervention will prevent rapid weight gain in infancy and overweight at age 3 years. Further, compared with control infants, intervention infants will have lower body mass index (BMI) percentiles at age 3. The investigators also hypothesize that control infants will gain weight more rapidly over time.
