I have a DS with ASD who is 3 1/2. He has some speech but at a two word level and limited understanding of speech. For a year now he has been put on the toilet at change time. He has just started doing wees on the toilet when asked and is happy with that. He refuses to go near the toilet for a poo and never has. He has constantly wet nappies between toilet times and never announces that he needs a wee although he does tell me when he is going to poo. My question is when do we withdraw nappies and what if he can't actually feel when he needs to go wee? Also how do I persuade him to poo on the toilet. He gets upset if I try. Any advice or tips would be helpful. Thanks for reading!
