I'll move this to education if it's not appropriate. Our DC's are starting at a new private school in September and therefore less children so more important that we get things spot on as they'll be in the school until they are 18. Last time we moved schools basically our eldest missed reception, straight into year 1 and the other started in reception. But it was almost as if we were never forgiven or allowed "in" because she'd missed those first 18 months.
DC1 can be too loud and likes to run around a lot and I know the girls don't really "get" her, so am trying very hard with her to talk about appropriate behavior. She'll swipe at her sisters if they are arguing, not other kids but obviously other kids see her clobbering her sisters and don't like it. DC2 is bullied to within an inch of her life right now with a horrid girl in her class she won't stand up to and that's one of the main reasons we're moving. She has 0 confidence. She's a dear little soul who wouldn't say boo to a goose but when 3 out 20 kids came to her party last week she absolutely crumbled, it was heart breaking. DC3 is oblivious to everything and just plays with anyone and everyone and the least of my worries apart from forgetting about the poor child.
So I plan to do all the play dates etc but thought I'd sit back and get the measure of things first, frankly i'm more nervous than them though.
