Maturity issues are so important. We have had our child in private schools since K4. His schools have also been advanced academically - until our move to FL. Honestly, I don't consider their programs here advanced - even though they sure claim it. The only part of the curriculum that is ahead is math and that is questionable. I honestly don't think he's being challenged academically. I think he's getting a good education and getting a lot of bells and whistles he wasn't getting before - more art, drama, music, play... More creativity... So, there's the trade-off. He's also having a lot of fun with school - loves it. There's more play and active time as well - which is so important and so lacking in many schools. It's no wonder our kids have such weight problems with all the packaged junk food and lack of activity. Anyway, that's a whole different topic...
The problem isn't academically - I don't even think the problem is the grade per se. The problem is so many people (especially in the private sector) holding their kids back for competitive reasons... So, I'm now trying to decide whether to move my child to yet another school and then move him back a year (although he is already not challenged - I'm afraid he'd be bored out of his mind) or just leave him in place and hope for the best. Most of the kids are already 8 - one will be 9 in January - in 2nd grade. I think it's easier for girls to be the youngest, but he's having a hard time with it. As advanced as he is academically and intellectually - he's a bit behind physically. He has a movement disorder which although mild impairs his coordination. I think it will improve, but being paired with such older and more physically driven boys is causing a problem. I do not want him emotionally damaged - I don't want him to withdraw and I'm not so sure that isn't the path on which we're headed...
He says he's happy, but he also doesn't have a new real friend. He has a couple boys he'll play with, but he's mostly playing with the girls. He prefers imaginitive play - most of the boys are doing sports during recess - football or whatnot. The upside is that he has improved a bit physically - the downside is that I see him not engaging a lot - he gets teased - he can't take that. He's far too sensitive. At his age I probably would have just popped them.

Joking - sort of - I did get to the point where I nailed anyone who messed with me - wasn't born that way - created. I don't want that to happen to my sweet, loving, kind, gentle and outgoing child.
We have some neighbor boys - one is exactly a week younger the other a few months younger - both are in first grade. They seem to get along so well - it seems to be a far better fit for my son physically... So, I am really wondering if, over the course of his education, he wouldn't be happier paired with younger children.
My only worries with that are, as I stated above, he is advanced - him being bored... Also not making the most of his abilities or losing work ethic. Yeah he's 7, but we do form and maintain that as we grow... When kids are very bright they already have to battle the idea of working for something - they think everything should come easily... The other worry is that he's large - he's 52 inches and nearly 70 pounds at 7. My husband is very tall - so I don't want him to seem like a giant. I suppose that's one upside of being with all these older kids - he's not the biggest... How can he be when paired with a kid that's nearly a year and a half older. My last worry is that he'll be bothered by the idea of being held back... I've broached the subject with him and he says no... Then again I asked him about switching schools and being in the same grade as his friend and he's interested in that idea...
I swear being a parent seems like one long struggle with trying to do the "right" thing and not totally mess up these little souls left in our care. I guess I just care too much.
I'm definitely open to input on trying to problem solve this.
