In order for that to happen, a parent needs to stop being in charge of the toileting like they did when he was in diapers. As soon as you know that your child has the basic knowledge and experience to go potty, let go. Become uninterested. Adopt the attitude that he’ll go potty when he goes potty. Stop any negative comments so the child isn’t gaining Parent Pie through negative attention. Don’t mention accidents, don’t give lectures, make no comments, nothing. Just silently help him change or clean up, or if he’s old enough, let him do it himself.
Potty training becomes a success when a child makes the connection between a full bladder, the need to stop playing so he can go potty, and the fact that this is his responsibility, not his parent’s.
