DS is almost 3.5yrs. Hes very shy/ anxious around other children. He even avoids crawling babies like they have a contagious disease! Wont go anywhere near his 8wk old cousin.
He's ok with most adults as long as I reassure him. No amount of reassurance will get him to interact with another child.

We had a friend with 2 kiDS- one older, one younger- over last week and aside from a little jealousy over his toys he didnt interact with them at all.

We have been going to MOPS once a fortnight for a few months and playgroup every week since the start of the year. They are run by the same church so lots of the same kids. But hes still not really interacting with the kids. Keeps to himself, wont participate in group times, etc. I think the only reason he was ok staying in the MOPS creche without me is because a friend of mine is a carer so he knows her. Even then he is nervous. Im not sure if I should be keeping him out until he is more emotionally mature, or put him in more activities or even daycare and get him used to having other kids around.

I dont want to make it worse.
