I have watched children from the ages of 4 to 12. If I watch them after school I make sure that all homework is done before they are allowed to play. During the summer I allow them to play outside as long as I am out there and they go inside to cool off when needed. If I am needed to I will stay overnight. That is only if it's needed.
