Evaluated the possibility that sensory exchanges during mother-infant (MI) cosleeping alter infants' sleep experiences and may help them resist some kinds of SIDS. Five MI dyads in Study 1 and 3 MI dyads in Study 2 were monitored using polysomnography while cosleeping or while sleeping in adjacent rooms. Study 3, which is still in progress, is using polysomnography to study 50 Hispanic, breast-feeding MI dyads while cosleeping or sleeping apart. Infants who sleep with their mothers and breast-feed are more likely to sleep on their backs, are aroused by their mothers at unexpected moments, breathe in small amounts of their mother's CO2, experience increased movement and feeding, and consequently exhibit greater vagal tone maturity. Thus, cosleeping infants spend less time in deep stages of sleep and are more likely to arouse and reinitiate breathing if necessary. (PsycINFO Database Record (c) 2013 APA, all rights reserved)
