Parents are often curious to know how their infant will do behaviorally and emotionally as they grow up, and if there is any way we can help parents understand what may lie ahead from a developmental standpoint for these babies. Rodrigues et al. ( 10.1542/peds.2016-4279) share with us in a new study the data they gathered longitudinally on a cohort of 323 infants all of whom had older siblings. These infants were followed for four and a half years with parents providing ratings of their emotional and behavioral issues as they moved through toddlerhood into preschool. Information was also gathered at the start of the study and ongoing regarding sibling behavior.
