My son sleeps from 5 am to 10:30 am and takes two or three short naps a day. i'm a little worried. is this normal?

Sleep: Does he sleep well at night? How old is he? If he sleeps all night, he may still need 2-3 naps, depending on his age. If he's substituting daytime sleeping for nighttime sleep, you may need to change his days and nights around. How is he going to bed- do you put him in his bed while he's still awake? Talk with your doctor about getting a healthy pattern.
