Well, certainly I believe that every responsible parents want good health for their kids. I, for one, would very much want my kids to be fit and healthy at all times. However, all of these assurances would have to depend on many factors; for example: Do parents have the free time to spend time with their kids for physical activities (outside the home)? Nowadays, with both parents working, hardly would they have time to do so. Can they afford to send their kids to a camp for school vacation activities? Some parents may have mortgage commitments. Are most parents educated enough about healthy eating habits for their kids? Some parents are not aware of such good recipes about good and healthy eating habits and so forth.
So my reply to this question is, concern parents should start reading or googling about how they can help their kids to have a fit and healthy lifestyle; and NOT working harder (in term of $$$), but I guess working WISER without having to spend that $$$ to keep their kids fit and healthy.
