DS now 2.11 has been doing amazingly well and been pretty much toilet trained for 4 months. But in the last couple of weeks we seem to be having at least one 'accident' pee wise a day. It's only ever when we're at home. It's usually in the afternoon. He seems to be doing it in purpose as it only happens at home and often after he's told me he doesn't need to go after I've asked him.
We've tried rewards system again. I'm at my wits end and finding it difficult not to make a big deal of it as he's so switched on, I'm certain he knows exactly what he's doing.
Any advice? Please!
