Somewhere between six weeks to six months of age your child should begin to sleep more at night and less during the day.
An infant may need 18 hours of sleep, a 2 year-old may need 12, a 10 year-old may need 10, a teenager needs 8-9 (which is still more than an adult’s average 7-8).
Human sleep cycles through stages every 90-120 minutes (light sleep, deep sleep, and dream (REM) sleep), and it is quite normal for your child to wake up with each of these cycles. The key is to make your child a self-soother and not a signaler.
By placing your child into bed before they are asleep, you allow them to learn to fall asleep in the environment of the bed (soothing their own self). If you rock them to sleep and then place them in bed, each time they wake up they will signal you (probably by screaming and crying) to recreate the rocking environment in which you have taught them to fall asleep.
Bright light signals the clock in the human brain (our circadian rhythm) to wake up and get ready for morning. A sleep environment should be dark (a dim nightlight is okay), quiet, and a good temperature. TV and video games are horrible for sleep and should be limited or kept off entirely as bedtime approaches.
We believe sleep is as important as wakefulness in our house, and we make each an equal priority.
