Question: how many hours a day should 3 month old sleep?
Answer: Most 3-month-olds need 11-12 hours at night and 3-4 hours during the day. Many 3-month-olds are still eating 1-2 times a night and some naps are just 30 minutes. This is all normal development at this age as it's highly unusual for babies to take four 1-hour naps.
