socialization in unfamiliar groups?

[Guest guest]

My son is 3.6 yo with global dyspraxia. He has been in speech

therapy for about a year and has made tremendous progress I

understand about 90 percent of what he says and he talks in full

sentences. Strangers understand some but not all of his speech. He

is very outgoing and loves playing with other kids and does well in

preschool.

My problem comes in helping him in a group setting with unfamiliar

kids. We just came back from a party where there were several young

boys around the age of 4. Most of them knew each other but my son

didn't know them. They couldn't understand some of what he said and

the evening just deteriorated. Because he couldn't seem to get them

to play with him, my son just antagonized them by taking something

they were playing with and they would chase him(one of his favorite

games is tag) When I would pull him aside (out of earshot) and remind

him it wasn't nice to take things without asking and then try to ask

the boys if he could play too, it just ended up in a tattling

session. Eventually they just said " Go away! We dont like you. " It

seemed to roll of my son's back but I know it won't forever and it

made me very sad.

How can I help him with situations like this?
