Yesterday was interesting, he did a wee about 1 minute after I posted, too late to get to the potty and ran off thinking he would be in trouble. 3 hours later I missed another wee as I had gone outside for a couple of minutes. I did get him as he was doing/finishing a poo a little bit later and grabbed him and put him on the potty. While he wasn't looking I grabbed some of the poo in his undies and when he got up off the potty I slipped the poo into the potty so he thought he had done it. Cheered and congratulated etc as if he had so he understood the potty was a good thing.

Today has been 50% in the potty so far which is success in my eyes.
