I will say first: we have 4 kids and my gymnast is the youngest so that plays into the picture. My oldest DS (marching band & soccer), 2nd DS (baseball, football), 3rd DD (volleyball, softball, Girl Scouts) and finally my youngest DD (gymnastics, Girl Scouts). Now, if we had fewer children she may be able to participate in more activities but that is the reality of a busy family. She is young and really likes have time to just play w/ her friends in the neighborhood.
P.S. does Black Ops count as an activity??? My oldest DS spends a lot of time playing. LOL
