Newborns sleep a lot — about 17 to 18 hours a day for the first few weeks and 15 hours a day by month three. But they’re almost never asleep for more than three to four hours at a time, day or night. The best way to make sure that your baby will learn the good sleeping habits is to teach them right away. Keep an eye on your baby to learn to know the signs when he is sleepy. If you spot the common signs of sleepiness (rubbing the eyes, pulling on his ear, developing dark circles under his eyes) put the baby right away in the crib. Soon you will learn your baby’s daily rhythms and patterns, and you’ll know instinctively when he’s ready for a nap. Also once your baby is about 2 weeks old, you can teach the baby a difference between day and night by playing with him during the day and then making sure that night time lights and noise level are down. When the baby is 6 to 8 weeks old, start giving your baby a chance to fall asleep on his own.

When you lay your baby in her crib, you’ll want to follow the recommendation of the American Academy of Pediatrics (AAP) that healthy infants sleep on their backs or sides.

Here is some updated information about baby sleeping:

The current AAP recommendation is for healthy infants only; it may be best for some babies to sleep on their stomachs. Before you leave the hospital, be sure to discuss the safest sleeping position for your baby with her doctor.
