Teens need about 9 hours. Generally, their sleep cycles are shifted later, so they tend to go to bed later and get up later. However, since most schools start early in the morning, most teens are sleep deprived.
My 13-year old granddaughter has a hard time going to sleep before 10pm .She gets up in the morning for school and she is always tired. What are some things can we do to help her change her sleepng habit?
