Sorry to bring up the topic of soiling - stop reading if you have a weak stomach!
My 5 year old DS has been diagnosed with ASD. We have always had problems with toilet training, and DS will still soil himself. When he was in YR R it was real problem with the school, but he manages to hold it in when at school. However home life is different. He'll go from diarrhoea to constipated quite quickly, and the size and volume of what comes out of his body would make a giant proud - and a lot of the time this all happens in his pants/on the carpet/under the dining table etc., everywhere but in the loo! He'll try and hide that he has had an accident, even though I have never made an issue of it (although same cannot be said for DH).
I just wondered if anyone else has experienced this? I am going to visit the GP next week about my DS' toilet issues to get a referral to a gastro paed, I don't want to brush this under the 'ASD trait carpet'.
