i find with the busyness of kids all day, my son (7) and i eat dinner anytime between 530 and 7. he is often not asleep before 10pm! but then i homeschool and let him sleep in as long as he needs to while i start with the dck at 8am. it works for us, and although sometimes i feel guilty that i let him stay up so late, it's often only in the evening that we finally get to relax and spend time playing games and hanging out together. i've decided it doesn't matter what anyone else thinks, as long as it works for us and he's still getting the rest he needs.
