when can newborns start sleeping through the night?
Oct. 25, 2010 -- There's light at the end of the sleep-deprived tunnel for parents of newborns. By age 3 months, and sometimes as early as 2 months, most infants are sleeping through the night, according to a new study, although their sleeping hours may not exactly match those of their parents early on.
At 6-12 months. From about six months, babies have their longest sleep at night. Between 6 and 12 months, most babies are in bed between 6 pm and 10 pm. They usually take less than 30 minutes to get to sleep (but about 10% of babies take longer). Most babies can sleep for a period of six hours or more at night and are waking less.
