Sixty-two preterm infants born less than or equal to 32 weeks gestation will be put into either the sensory-based intervention (experiment) group or traditional care (control) group. Consecutive admissions at St. Louis Children's Hospital (SLCH) who are hospitalized in a private NICU room will be recruited. The parents of infants in the sensory-based intervention group will be educated and supported by trained therapists to give different positive sensory experiences to their infants while hospitalized. The traditional care group with receive normal, standard care while hospitalized. For both care groups, infant neurobehavior, sensory processing, and parent mental health will be measured at term age prior to hospital discharge. Child development, sensory processing, and parent mental health will be measured again at age one year (corrected). Differences between the two groups will be explored.
