Well, I don't know how most parents do it, but for us, we let the kids make up their own schedules and it works for us. There is a lot more sleep than I would have ever thought. In fact, last summer, we let Matt sleep for a couple of weeks (seriously it was something like that long), and he woke up like a half inch taller.
How do parents keep their kids on a schedule during the summer? Why do they do it? I'll never understand.
Maybe they need more control? What do you think?
