She really wants to be active this winter,but all her schools sports are over for the year. She is 12. Where do u think she could still find some sports to join? or at least what should she do?
see if there are some non-school clubs in your area and talk to the coach. i got accepted late on a wrestling club as a kid.
or you can join a martial arts class(i did taekwondo as a kid and i recommend it), they can't really refuse you.
