DS is 2.5. He's been in pants for 10 days and has done really well with wees - a max of 1 accident a day and several completely dry days. I've not been prompting him and he's taken himself off to the potty which he then demands DD empties but we've had no joy with poos. I've seen him pull the face and asked if he needs a poo/suggested he sits on the potty and he always says no. Within 30 seconds there's a poo in his pants. I've been taking him to the potty and getting him to try and do more but no luck. He just says he'll try again tomorrow.
Any suggestions? I don't want to be cleaning poo out of pants forever!
