Thanks for sharing your experience. Our K is a half day K at our public school, at a private school that is close that I have considered (which is fairly affordable at this point), they have half day K for half the year, and then combine both classes for a full day to transition them. DS does not take naps, he did up until this fall, but he is in a pre-k afternoon program 3 days a week so that broke him completely of the naps and he does fine. He requires little sleep, but sleeps well at night. He is also a really big kid, looks bigger (taller and solid) than most Kindergarteners already. I guess we will have to wait and see. He is very outgoing and talkative. He gets into a little trouble at times in his pre-k, but does pretty good. Mostly because the kids are his age or a little younger so he goofs around with them like they are younger. I agree with you though, even going to 1st will not challenge our DS either. And he seems to think K will be fun. Of course he thought pre-k would have history books and was disappointed in that. So many choices. I wish there was an obvious answer at times, I am sure everyone does.
