Mj. Hayes et al., EARLY-CHILDHOOD CO-SLEEPING - PARENT-CHILD AND PARENT-INFANT NIGHTTIME INTERACTIONS, Infant mental health journal, 17(4), 1996, pp. 348-357
This study investigated parent-child interactions during sleep onset a
nd nighttime arousals in a rural sample of preschool children. The rol
e of co-sleeping in relation to sleep habits and night waking was exam
ined using parental self-report of both current and retrospective slee
p patterns. The results showed that Solitary Sleepers engaged in more
complex bedtime routines, and had more longstanding and stronger attac
hment to security objects and sleep aids, than did Co-sleepers. Infanc
y precursors to co-sleeping in early childhood were a history of breas
tfeeding, night feedings in the parent's bed, and returning to sleep i
n the parent's bed.
