Sorry - this is going to be a bit long, but I need to explain the background first. Warning - don't read if you're eating...
DS2 (6, ASD) is now completely toilet trained for wee in the day time. He goes independently to the loo and can manage hand-washing and flushing, though he needs reminding. He asks to go if a toilet isn't readily available, at home, at school and when we're out.
However, he has never done a poo on the loo. Since he's been out of nappies (about 4 months) he's had numerous poo accidents in his pants, though never at school. Recently he's stopped doing this in the day but always goes in his night-time nappy, usually just after going to bed, but sometimes in the night. We usually dress him in all-in-one pjs to prevent smearing. He has always had a stairgate on his door to keep him in his room - he is usually very excitable when he goes to bed and takes about 2-3 hours to fall asleep.
Last weekend DH and I decided that we weren't helping him to become poo-trained at all by this approach. So two days ago we moved the barrier further up the corridor, which gives him access to the bathroom. We put his toilet chair in the bathroom and are getting him to sit on it before he goes to bed (we thought it might be less intimidating than the toilet itself, especially as he trained v quickly for wee using it). With a huge gulp we took him out of all-in-ones and put him in two piece pjs.
Both nights so far he has been as high as a kite. He has smeared and thrown poo horrendously - worse than ever before. On both nights he has eaten some of the poo - again something he has never done. Tonight for the first time ever he climbed over the barrier (DS2 doesn't climb!) and put some of the poo in DH's wardrobe. He doesn't seem at all distressed - just the opposite in fact.
I'm afraid we caved in - we put him back in his all-in-ones and moved the barrier back (making it very high). It'll gave us easier evenings, but it's not going to help in the long run, is it?
What is going on? And what do we do? I would REALLY appreciate your insights on this.
