Tips for a quality sleep

1. Avoid watching TV, eating or discuss emotional problems in the bedroom. The bed should be used only for sleep and intimate relationships.

2. If read a book to relax, make sure it is not too stimulating. Adventures, thrillers, mysteries and action books on important topics tend to keep mind active long after you stop reading.

3. In the evening, try to diminish the child’s bedroom light (no matter how early it is) to prepare them for bed. Thus, when the room will be lit in the morning, they realize that they need to wake up.

4. Do not let pets get into your bed. When pets are noisy at night, move them to another room.
