Question: how many hours should a 3 month old sleep in the day?
Answer: How much should a 3-month-old sleep? Every baby is different, but a typical 3-month-old needs between 14 and 17 hours of sleep in a 24-hour period, including three to four naps totaling four to six hours. However, it's also normal for 3-month-olds to sleep a little more or less than that.
