Abstract
161 women and 111 men, Caucasian college students, provided retrospective information about their patterns of sleeping during childhood. The practice of co-sleeping was common, with 33.7% reporting that they co-slept in their parents' room during their first week after birth, 29.4% during the first month after birth, and 27.5% during their second month after birth. In addition, 6.3% of women and 11.9% of men reported that they co-slept during the entire first year after birth. Finally, a sex-specific pattern of co-sleeping was found with more women reporting that they co-slept with their parents during their first week and first month after birth, but a greater percentage of men than women reported that they co-slept with their parents at older ages. It appears that girls are removed from the parents' room at a younger age and more frequently than are boys.
