I have twin boys who are almost 10 and going into 5th grade. Last year we started the school year with an 8 pm bedtime and as the year progressed I moved it to 8:30 pm. They want a 9 pm. this year but I am not going for it. We are starting the school year at the 8:30 and I don't see it moving until close to the end of the school year - they need the sleep and we all know that kids don't go right to sleep - they think we don't know that...LOL. When I talked to the other Mom's of the kids I like in their class (better behaved and pretty good students) they also have similiar bedtimes. Hope that helps.
