We began toilet training Alex when he was two and a half. Now, over a decade later, it's possible that we may have finally achieved that goal.
For the last month, Alex has been independently going to the washroom when he needed to go. We've still had some accidents but on a small scale, not the full on go-in-your-pants level that we used to. And each accident has been followed by a proper production in the toilet.
This is a huge deal and I give the credit to our behaviour consultant (and to ourselves). None of us were sure this was even possible but we all agreed to keep trying, even though the statistical odds were against us. We began with having him sit on the toilet for 3 seconds and through small incremental steps and frequent rewards, managed to get him comfortable with sitting on the toilet for several minutes, got scheduled toileting breaks into the routine, encouraged "dry pants" and now, we seem to have achieved independent toileting.
It's not a guarantee yet. We'll have to see if the behaviour holds through the summer and into the next school year. If it does, then we can declare victory. But for now, something which seemed impossible is now very probable and I'm proud of what we've achieved.
