My brother has sensory issues with shirts and anything touching his knees clothing wise. He also hates the feel of socks. Whole other thing with because he can and does talk to us about it. The rule, when we take him, out, is that he has to dress for the weather (no shorts in winter, no going shirtless, shoes and socks must be worn). He hates it and says if we make him wear stuff like that he won't go with us. And he'll try about once every few times to take something off in the car. He does that, the car gets turned around.
Abbie doesn't seem to have any limits like that. Anywhere she goes the shoes come right off. I can see going barefoot at home since it is warm enough. But away from home? I don't think she takes them off at school. At least I didn't see them off in the few times they filmed her there. The school seems to get her to do these basic things pretty well. If A & P are such experts why aren't they able to follow through with what the school does? Small children learn this, why can't she?
