My son is 7.5. Year 3.
A usual week:
Monday - nothing
Tuesday - external from school tennis (plus this is a games day at school so they play 2 hours of whatever sport it is that week in the morning)
Wednesday - nothing
Thursday - hockey straight after school, at school. Pick up, and then a 30 min piano lesson
Friday - cricket straight after school, at school.
Saturday - nothing
Sunday - sometimes Parkrun, always swimming in the afternoon
He goes to a very sporty private school so a lot of this is to keep him involved, keep his fitness up and generally is in the spirit of the school. However, I worry that it's quite a lot.
He seems to be coping ok, but sometimes complains of being tired and hungry - isn't that normal for 7 year olds?
