A. hi dear Generally, newborns sleep about 8 to 9 hours in the daytime and about 8 hours at night. But they may not sleep more than 1 to 2 hours at a time. Most babies don't start sleeping through the night (6 to 8 hours) without waking until they are about 3 months old, or until they weigh 12 to 13 pounds.
