Well DS has one good friend. He & my girls are the only kids he plays with. If he doesn't have them around he won't leave my side, or my lap.

If someone talks to him he'll look at them, or he might watch others, but he won't otherwise. Doing a shopping trip is too much. It seems more that he can't handle the stimulation of dealing with people, than anything. He screams, doesn't want to go into shops & nothing stops it til we get home... often he'll still go on for hours with the tiniest things setting off tantrum/meltdowns. Sometimes it can last days...
