Open we have been to a birthday party today too. He doesn't get invited really but he's had 2 invites in the past 6 weeks.
Ds is exactly the same, sticks out like a sore thumb, it's clearly obvious he is a SN child & the older he gets the more he stands out bless him.
I don't see him with his class bcos he starts later and finishes earlier at school so I don't see the other children or parents, but I've seen today and at the last party a lot of the children look terrified of him. They either freeze or flinch when he goes near them. He sat on the floor beside a little group of girls to eat his food and they shuffled forwards away from him. (Which I thought was really nasty!) Children don't talk to him either and I noticed that at the last party too
he doesn't notice though so never mind.
When they lit the birthday cake at the end ds barged in and tried to grab the lit candles
he got told off by the dj for going behind the dj area a few times and touching what he wasn't supposed too and he kept making a beeline for the party food 10 mins into the party lol, & he didn't understand the party games, but he had loads of fun for 2 hrs running wild.
I was having to walk around and supervise his every move which makes him stand out more obviously.
He joined in though, dancing away and breakdancing and god knows what ever else it was he was doing on that dance floor 
I'm pleased I took him though. X
