He is quite bright, knows what a potty is and what it is for, and after buying one last night has sat on it and grunted and pretended he had done a poo, wiped his bum (sort of) and that was it. I left him naked today and he has no idea he is going, apart from the noise (!) He was sitting on his chair and pooed all over it without really noticing, whilst sitting on it. Is it too early to start with him? Or is this how it starts?
