ds2 is 12 and just finished yr7, i know your dd must be a school year above, ut this is what would be expected of ds2 for the summer holidays when we are home. We are fortunate to be away for 3 1/2 weeks of the holidays so he will be with his parents and siblings and doing the same things, lying by the pool, swimming and teen clubs for the first week of the holidays.
When we are home i will be working 2 full days a week but home the other days, he will have to go to his grandparents for at least one of the days i am working, the other day he can stay in bed until 12 then go out with his friends or to a friends house. the 3 days that i am home, doesn't mean that we will be out every day doing activities, some of those days i intend to just relax around the house or be clearing out bedrooms. Again on those days he will be free to come and go as he pleases.
This usually means, going to the local park and playing rugby or biking, down to the river fishing or just sat there chatting and letting the world go by. He might go to the local shopping precinct for chips and costa, and then across to the park near there for the skate park with his scooter.
I might drop him and a friend in a neighbouring small town to meet school friends, or catch the train (3minutes) into the nearest big town for a spot of mcdonalds/primark/browsing in Hollister and superdry.
i anticipate that his pocket money will be about £20 per week, but if he is eating lunch out then he will be expected to be home for dinner, or he can take sandwiches/crisps/cake/cartons of juice out for lunch and snacks and buy something more substantial for dinner. I will not be funding 2 meals a day out.
I would also, dependant on behaviour for other weeks, consider giving him enough cash to buy a new t-shirt or some shorts etc, but that would probably only happen once in the whole of the holidays.
His older brother is 17 and gets £20 a week as well, hes old enough if he wants a top up to get a job!
oh we have free swimming here for the holidays as well.
