For the child with relatively severe problems and a lengthy home program, the parent may wish to only utilize a half-day school program. You should not expect your child to spend six hours in school, plus travel time and expect them to perform well at home for a home program which takes two or more hours to accomplish. Many families have discovered that if they take the children to school themselves and pick them up that it greatly reduces the child's time away from home. A rule of thumb for appraisal of school versus home time, is that the greater your child's problems the greater their need for individual attention, and the greater the child's needs for individual attention the less able the school to provide for your child's needs. All the activities mentioned and others may be positive and productive but must be viewed within the context of the child's needs.
Time is limited.
Time used is invested so invest it wisely. Each extracurricular activity that is worthy of the investment must be directed toward a particular need of the child. It must also be incorporated into the child's schedule on a priority basis. Because an activity is fun, a friend is involved in the activity, or because you think that it would be nice may not be sufficient reason for the investment. Some children really want to play the piano.
