Quick story. I have twin boys ds2 (2 mins younger) has ASD. They will be 4 later on this month. Over summer hols ds2 decided he wanted to start using the toilet. Great. Problem is he often has accidents at least once a day and has never pooed in he potty or toilet. He has been in his pants and all over the floor and his bed. He knows when he is dirty but is not aware of going! Has only been doing 6 hours at play school before hols. Now will be there for 15 hours a week with one on one helper. Don't know what to do for when he goes back. Pull ups or pants? Please help me.
