My 3 year old step daughter is completly potty trained and has been for almost a year. But recently, shes just too busy playing or whatever to go to the bathroom. She doesnt normally pee in her panties but she poops in her panties. You can tell that she actually has to push to get the turds out because of the way the texture is. I have tried everything including the corner, talking, telling her is gross, throwing away her panties, putting her back in a diaper. She knows that its not right and that she needs to poop in the tiolet, she just wont. Her mother doesnt do anything as far a disipline when it comes to this. Im not sure what to do. Anyone have any suggestions?
