The goal of this observational study is to discover features of normal and disordered motor-voice profiles that are biobehavioral markers of physical disability in infants.. The main questions it aims to answer are: Identify voice factors among infants with newborn-detectable risk. Identify association between individual characteristics (Gestational age at birth, global function, motor-function) and voice factors. Examine unique features of voice production that are present in infants with high-risk for Cerebral Palsy (CP). Participants will be asked to upload a 3-minute videos of their child at term-age, 3.5-, and 9-months of age. At the 3.5-month and 9-month time point parents can choose to attend an optional in-person assessment with their child.
