Mine is at school, not riding the bus. There's about an hour between waking and leaving for school, then four hours between school and bed. 2 1/2 of those hours are taken up with getting ready for school or bed or eating, so 2 1/2 hours a day free on a weekday, then all day Saturday and Sunday. They get some free time at school (it's kindergarten) about 1 1/2 hours a day.
