Extra curricular activities in secondary

DD has taken up activities as she has got older - Air Cadets 2 nights a week 7-9.30pm and all of one weekend day generally. Then piano - one lesson a week with 10 hours practise a week on top, Art - graffiti project one night a week and a long weekend away every other month... on top of that she is doing Art and Music (as well as English lit) at A level - both VERY high in coursework needs.

and to top it all, she now has a boyfriend she wants to see twice a week and one day at the weekend - things are going to have to change...

Having said that DS is not going to stop the activities he enjoys but the venue. He is going to carry on the same sports at school. Not sure the quality but assume there will be lots of advanced players at the relatively large school. Swimming will be difficult to carry on though as there is no swimming pool at his new school. I am thinking to find a club running on Sunday but haven't found any for advanced swimmers yet. I don't know if it exists really!

Got to admit that DD (now Yr9) had to drop a load of outside activities due to the fact that she was just so tired in Yr 7. Also pressure of homework etc. But she is lucky that they have a lot of lunch time activities that she did instead. (1hr 20 for lunch). She has started to take on some new evening activities now she is older but still only Tue & Friday evening. She always kept going with hockey on Saturday or Sundays.
In Yr 7 she just wanted to come home from school and relax (once homework was done). There is no way she could have kept up with her YR6 activities.

DS currently spends nearly 18 hours on the 'out-of-house activities (journey is not included), plus occasional weekend time for matches, concerts and events. We already made a bit of adjustments last year as one activity was getting too demanding. He is stopping all apart from the weekend activities (10 hours) when he starts secondary in September. We are feeling very sad about it as all the activities are such important part of his life. But I'm very afraid logistically it's difficult to carry on.

I too am wondering this. The 'out-of-the-house' time spent on activities is currently 11 hours, plus another 2.5 hours on music practice. Plus occasional additional weekend time for concerts/shows/events. In our case this is spread over several different activities. DD doesn't want to stop anything. I don't know whether to just let her carry on and see if she falls over come September or say now that one at least must stop.
