If you awake at night:

Remember that the timing of sleep varies from person to person: some need to sleep at least eight hours, for another five or six are sufficient.
If you usually rocked him, pamper him or singing a lullaby to put him to sleep, may have trouble returning to sleep if he wakes up alone at night.
When you approach your baby to comfort him, keep the lights low and talk to him gently.

If you wake up too early:

Choose curtains or blinds to prevent the morning light to penetrate into the room.
Let him make sure the toys with which to enjoy morning, while the rest of the family is still asleep.
If your baby usually wakes up early, just be patient.
Usually, asylum, or the beginning of the school, will tend to sleep longer.
