SIL always signs her kids up for programs that have practice multiple times a week, plus games every weekend. If they miss 1 practice during the week, they cant be in the following game. She even convinced her sister to sign up her DS (7). He had practice 3 nights a week, plus games. He basically had to come home from school and eat right away so he wasn't going on a full stomach. He didn't get home from practice until 7:30-8pm, so he had to go right to bed.
DS's soccer coach's DD (7) does 4 different sports/activities that i know of, plus her DS plays a couple different things as well. Pretty much every day/night they have practices or games.
I dont think I would ever allow my child to do that much stuff. For one, I want my child to have down time and not be going going going every single day. I also want him to have time from friends, homework, family and such. And for second, I dont want to be running all over the state all the time to take him to these places.
Do your kids play sports/activities? Do you have a limit of how many they can do?
