YABU
School is a long an tiring day for kids, the should be allowed some down time. It doesn't always have to be homework and imaginative play.
I used to come home, watch kids tv until 5 when my much older bro watched home and away and neighbours until 6. I used to watch with him. Potentially not age appropriate but very nice for a little sister to have a cuddle with her big brother for an hour! Then music practice for 20 mins, then tea, then homework.
I can't actually remember what I did after homework. Probably drew for a bit or hung out with my parents before bath and bed.
In junior school that was 3 nights a week as I had activities 2 nights. Suppose we didn't really have much homework then.
In secondary school I had things on probably 3 or 4 nights a week depending on the sports season.
Watching 2h of TV a night didn't do me any harm; straight As at a level, 1st class degree, plenty of friends, good job. Unfortunately my working hours don't allow for much (any!) TV in the evenings now, but I'm quite partial to vegging out in front of come-dine-with-me for a few h on a Sunday!
