I hear ya Blossomhill - though my ds is obviously alot better now than pre medication.
We went out today and there was a childrens magician with a puppet doing a ventriliquist (?) act. My ds could be heard WAY above the other children (and adults) cos he laughs so loudly. It is so lovely to hear him genuinely enjoying himself, (as he does a lot of false, put on laughing too) but it began to draw stares from everybody after a while.
Later on we went back to the full showing and we sat on the front row, but I think that my ds thought the show was only for him, no one else. Even when the magician asked for the assistance of a little girl, he stuck his hand up immediately and shouted "me, me!". The magician said "but you're a boy!" but it didn't seem to deter him. Half way through the act, his legs started kicking out and swinging about so I sat him on the chair next to me and gently lay my hand on them which is the sign to calm down the leg movements.
I pretended not to notice that other parents and kids were watching, but it was nice that it was a good reaction for him to have rather than drawing stares when he has a tantrum/meltdown, which obviously is awful.
Our shopping trips on Monday eve and Thursday are always alot nicer as he gets involved by pushing the trolley and sometimes pretending to be a crane lifting what I need into the trolley (though this can take a long time, so not one to do if you're in a bit of a hurry!)
I wish you all the luck - oh, just think of how much easier your life will be if your dd enjoys shopping from now on! (((hugs)))
