Dear A., '
I think your idea of before care is very smart because teenagers do not think in a straight line and I have read articles saying that they need more supervision, not less supervision. This society also gives them too many temptations such as TV, internet, etc.
The only part I was not sure about is taking his allowance to pay for the before care. If he is a good kid and gets good marks at school, maybe he would feel the allowance is drastic? I do not know.
I have a teenager myself, a girl, and overall she is good but it is scary what they can get into.
