ds3 (aged 4) has asd - one of the times he kicks off hysterically is when he has to go for a wee or a poo.
He always says "I don't need a wee" even when he is actually weeing. Or "I don't know how do a wee". Or "I did one yesterday". He kicks, screams, punches me or dh whenever we take him - we may as well say "Right, time for your head to be chopped off!" judging by his reaction.
He soils his pants and wets himself after saying he doesn't want one but then denies it belongs to him. If anyone can give any tips on how to deal with him, I would be soooo grateful. It's driving me bloody nuts, quite frankly.
