Any suggestions would be welcome please.
He's a pfb, and I look after him full time.
We go to a toddler group, a creche (I stay with him) each week, as well as swimming lessons and occasional park meet-ups / coffee with friends, so he sees other children regularly.
He had bad separation anxiety from about 7 months, although it has much improved now. He is only happy being left with his grandmothers (or my DH) but he's now happy to approach and 'chat' to other adults (as long as they don't try to touch him before he's got used to them). He is still scared stiff of other children though.
He has a strong sense of personal space and hates anyone (adults or children) invading it. He hates being in a small enclosed space with another child (or with an adult he doesn't know). He also gets upset if there are other people blocking the way from him to me.
Friendly children are the worst as they come up close to talk to him or reassure him that they won't hurt him. He just screams hysterically. Sitting on my lap while another child approaches is still terrifying for him.
He did seem to be improving, but we visited friends at the weekend with a friendly 3 year old who just wanted to talk to him / give him toys etc. DS was completely freaked out and spent most of the day sitting on my lap, crying or bf'ing for comfort and reassurance.
Since then he has been terrified of any child anywhere near him. We had the same situation (only not quite so bad) last time he was in the same room with a child who wanted to interact with him. In a busy situation (like creche or the changing rooms at swimming) he now wants to stick right by my side at all times.
He is very verbal and is keen to communicate with adults but is not easily understood by people who don't know him well, and he doesn't really use words to communicate with other children yet.
When not feeling worried about other children he's happy to go off and play independently although he likes to know that either DH or I are around so he can find us if he needs us.
He is very big for his age (99.6th centile height/weight) but is equally scared of crawling babies half his size as well as bigger children.
I am dreading 2 days of visiting family at Christmas where my 3 year old nephew will be wanting to play with DS and give him cuddles.
Any tips?
