Honestly - I have long since given up the idea that I could force/encourage/cajole my kids into doing anything they don't want to do. Exceptions being swimming lessons (because - safety) and music lessons - because it's a good idea and they have some talent there. Even with music I don't push the practicing - they do what they do, and still seem to be learning and getting something out of it.

Other than that - it's not worth the battle - a big waste of time, money and good will all around to try to push them into a sport or activity they've decided they don't like.

I have to say - I do help DS7 with changing after swim lessons. He has DCD and really would have a hard time doing it himself - especially when standing there shivering. Ditto with collecting his things from school at the end of the day. I'm sure he will eventually develop these skills - but it will take him longer than other kids.
