Babies sleep a lot, but wake frequently.
Seniors may not be able to sleep for as long as they once did. But all of us, young or old, should try to make sure we get our fair share of shuteye. Infants have no sleep schedule, and it's not a good idea to try and set one. By about 3 months of age, they should settle into a pattern and sleep for longer periods of time without waking. Gradually, the time spent down at night will increase and the number of daytime naps will decrease.
