Professor, Human Development and Family Studies
Dr. Hart focuses on psycho-social development in infants and young children in the context of their relationships with parents and siblings. Her current research aims to apply her previous findings on infant jealousy toward developing methodology for helping parents and firstborn toddlers prepare for the arrival of a newborn baby sibling. Her goal is to address the age-old problem of sibling rivalry by promoting a smooth transition, hoping that this will serve as a basis for helping sibling relationships off to a good start and preventing sibling rivalry. Along with faculty in the department of Nutrition and the Pediatrics unit at the TTUHSC, Dr. Hart is also working on projects with premature infants and their families. .
