OK, he doesn't seem that bothered at the moment, so why has it upset me?!!!! This is going up to yr4 and he has been part of the same little group of 4 friends since Reception. Even in Yr3 when they were mixed up for the first time he still had one of them with him.
I just feel a bit sad for him - I know they will still meet up at playtimes etc and he can now forge some new friendships - but just needed to tell someone!
little ramble over .........
