Children need rest . It's good for children to go to bed and get up about the same time each day. Regular sleeping hours and good sleep habits are beneficial for normal physical development. Most children need at least eight hours of sleep each night. They may need extra sleep as they move into a more rapid growth spurt.
Adequate exercise is important for the preteen.
Children have different interests and physical abilities that influence their choice of exercise. Children who watch television a lot often don't get enough exercise. If a child isn't getting regular exercise, the parent may want to help the child find activities and develop skills that provide it. Busy parents may feel many pressures from family and work responsibilities but should take time to visit with their children about physical growth and development. Preteens need the kind of support, love and concern that their parents are in the best position to provide.
