Rates of sleep-related infant deaths have remained stagnant in recent years. Although most parents are aware of safe sleep recommendations, barriers to adherence, including lack of access to a safe crib, remain. The objective of this study was to describe parental knowledge and practices regarding infant sleep position, bedsharing, pacifier use, and feeding practices before and after receipt of a free crib and safe sleep education. Bedtime Basics for Babies (BBB) enrolled high-risk families in Washington, Indiana, and Washington, DC and provided them with cribs and safe sleep education. Parents completed surveys before ("prenatal" and "postnatal") and 1-3 months after crib receipt ("follow-up"). Descriptive and bivariate analyses were completed. 3,303 prenatal, 1,483 postnatal, and 1,729 follow-up surveys were collected. Parental knowledge of recommended infant sleep position improved from 76% (prenatal) and 77% (postnatal) to 94% after crib receipt (p < 0.001). Intended use of supine positioning increased from 84% (prenatal) and 80% (postnatal) to 87% after the intervention (p < 0.001). Although only 8% of parents intended to bedshare when asked prenatally, 38% of parents receiving the crib after the infant's birth reported that they had bedshared the night before. This decreased to 16% after the intervention. Ninety percent reported that the baby slept in a crib after the intervention, compared with 51% postnatally (p < 0.01). BBB was successful in changing knowledge and practices in the majority of high-risk participants with regards to placing the infant supine in a crib for sleep. Crib distribution and safe sleep education positively influence knowledge and practices about safe sleep.
