...commented his teacher yesterday to DH.
I am a bit worried about him, he doesn't really seem to fit in at all and can be a bit of a loner - the teacher says he's really shy, which is true, at school.
Outside school he is really chatty and sociable and plays non-stop with his younger brother and any visiting children.
I don't know what to do to help him "fit in" more - invite other children back to play?
There are only 7 in his age group, and they are the youngest in the playground, which doesn't help.
