Just that really. We've got two v sporty DC's aged 7 and 9. They do several sessions a week both outside of school and as part of school extra-curricula stuff. The oldest wants to try an additional thing but I'm wondering what is too much?! They're young, but enthusiastic so I don't want to curb that. I'm just worried we won't get the right balance. DP is no help as he doesn't get the concept of them possibly getting too tired so would encourage them to do everything (not "make" them though, very important distinction, obviously).
