Each of my children is allowed one extra curricular at a time outside of piano lessons.
It's because I am too much of a homebody to want to leave again after I get home from work each day. smile I think it serves my children well. They prioritize their interests, they know how to be self-entertaining, and we have extra money for family fun.

It works for us. I think if your son is asking for more home time, you should provide it. smile
