i dont have any advice for you... we are in the same situation with DD. she will do wee's in the toilet but when it comes to poos she crys for a nappy or to go to bed as she sleeps in a nappy. She did one poo in the potty by accident and she freaked out big time, shaking screaming and crying. has also done poop in her nickers twice and had the same reaction. I dont know how to fix it and have just backed right off- nothing has worked for us. Will try again a a couple of months time. Good luck, i really hope you find a solution!
