In the evening, during the few hours before the start of your sleep phase, you enter the forbidden zone for sleep, an especially interesting period in which sleep is nearly impossible. If you tested your ability to nap at various times of the day, you would find it the most difficult to fall asleep during these evening hours: on the contrary, at those times you feel more awake, alert, and focused than ever. The same applies to your child. In fact, awareness of the forbidden zone turns out to be critical for understanding and treating certain common sleep problems in children.
