Started on Saturday.
DS1 is quite OK at sitting on potty and has done both wees and poos in it. Physically, he can wee and poo when he wants / needs and gets that the potty is now the place to do it when asked. He has had quite a few accidents, but they are moreoften 'dribbles' that I notice, put him on potty and he does a huge wee. Then he is very chuffed with himself.
BUT, he isn't asking to go on at all and when prompted, he says he doesn't need to wee (even though I know he does).
I'm not sure if this is going to work yet, as he isn't motivated or inclined to ask. He doesn't show any upset when he does have an accident (the dribbles he isn't noticing).
