Do you restrict what they spend it on? (Crack cocaine, knives and drugs being a given obviously.)
DD is 9. She gets pocket money every week in return for somewhat vague duties round the house. She had a Nintendo DS for b'day this year and has spent her pocket money on second-hand games on Amazon for which she has gone without any money for a few weeks. But this time she wants a new game which will basically cost her 12 weeks pocket money. She won't whinge and won't ask for anything else (she doesn't do that), but I suspect that she will regret it and will have got bored with it well before that time. Bearing in mind that we are also going on holidays in 2 weeks.
Should I put my foot down?
