Developing a rhythm

Newborns sleep 16 or more hours a day, but often in stretches of just a few hours at a time. Although the pattern might be erratic at first, a more consistent sleep schedule will emerge as your baby matures and can go longer between feedings.

By age 3 to 4 months, many babies sleep at least five hours at a time. At some point during a baby's first year — every baby is different — he or she will start sleeping for about 10 hours each night.
