This page is part of a collection of short articles called Brief & simple, which together make up a quick summary of The Possums Sleep Program in plain language.

Sleep (for all humans) is controlled by

• The body clock (also known as the circadian clock)

• Sleep pressure

The body clock is set by daylight and activity. It tells your body when it is night and day - when it is time to be sleep or be awake. Your baby's body clock takes a few weeks to develop after birth. You can help your baby's body clock get in sync with yours by having your baby nap in the middle of lots of daylight noise and activity during the day.
