Maybe I can answer that question with a few questions.
Obesity is a major problem among children in the United States.
Lack of exercise is a big problem. You would save time and wear and tear on your car by having them walk and make them healthier at the same time. We wouldn t dream of giving a baby on baby food all the chocolate that he wants because we know it would make him sick. His body can not tolerate that much chocolate even if he desires it. In the same way, an older child can t emotionally deal with the overload of toys.
