Just that, really. He is 2.8 and now is happy to use the potty or toilet when he's not actually playing with anything, or eating, but if he's in the middle of a puzzle, or playing with anything really, or has a friend round, he won't say anything until he's finished weeing in his pants. At the mo he gets a chocolate button when he does anything in the potty, lots of praise and seems very proud of himself when he does manage it. We've also tried stickers but he's not really into that.
