Infants with neonatal abstinence syndrome (NAS) who are cared for in a Neonatal Intensive Care Unit (NICU) often display symptoms including hyperactivity, irritability, jitteriness, poor feeding, and poor sleep patterns. The recommended first line of treatment to relieve these symptoms involves nonpharmacological interventions. The purpose of the current pilot study is to provide preliminary data to assist in the design of a larger scale study to examine one nonpharmacological intervention, weighted blankets. The pilot study will assess the feasibility of a cross-over randomized controlled design to study the impact of a weighted blanket on infants' symptoms of NAS.
