Hi P.,
So we too were in a similar situation. Last Oct. we moved and our 6 year old had already been into K for a couple months and where we were living it was full day. Where we moved to, it was half day w/ the option to do full day if you paid $2500 and were put into a lottery...needless to say we went with the half day. I can say that our daughter transitioned so well. The half day has actually worked out much better than the full and yes, she did say how she missed her "old" friends, but kids at this age make friends on a daily basis so after the first week or two of saying she missed them, she doesn't even mention her "old" school anymore. If it's brought up, of course she'll remember it, but she fits in so well with her new class that it's not the topic of conversation anymore. Do I wish that we had moved before she entered K, yes, of course, but for my own reasons, not because she didn't do well. It just would have been nice to have started and stayed in one place. However you are thinking about having him do K for a full year and then move, I could almost guarantee that he wouldn't be too upset. Yes, of course he'll make friends and some good ones at that during K, but kids lives are ever changing and if it's not him moving, it could be his "bestest" friend who is moving and he'd have to make a new one (if you get what I'm saying and where I'm going) :) I wish you the best of luck, kids are really resillient, it's amazing how well they bounce back. Now don't get me wrong, there are also kids that don't bounce back so well and are very attached, it depends on your child and what you think is and will be best for him...
