Hi, my son will be 4 next month he is potty trained (only in the house) but he refuses to have undies on unless he has a nappy on. I'm guessing he doesn't like the feel of them? (Has sensory issues) How can I get around this? My son is on the asd pathway and has a speech delay so he can't tell me when he wants to go the toilet, he will just do it when we are out. I am slightly worrying for when he starts reception in September incase he is still in nappies, I know that's it's a long way away but I can't help worry incase any of the kids pick on him for wearing them still. Any help would be appreciated
