Is it normal for a one-year-old to sleep this much?

Q: My great niece will be one this month and she sleeps a lot. She goes down for the night anywhere for 8 to 10 p.m., sleeps through the night and doesn't wake up until anywhere from 9 to 11 a.m.. Then she will be up for one to two hours and go back to sleep for at least three hours. On occasion she takes more than one of these long naps a day. Is this normal?

A: Your great niece sounds like a great sleeper! By the age of one year, most toddlers are sleeping 10 to 15 hours each day. On average, 10 to 12 of those sleep hours are at night. The rest of the sleep hours are in one or two daytime naps. Since your great niece has a wide range of bedtimes and morning wakeup times, I would suggest keeping a diary of her sleep hours. Don’t forget to write down her napping hours, too. Bring the diary to her one-year checkup to review with her pediatrician. Her doctor will be able to make sure that your great niece is getting the perfect amount healthy rest her body needs.
