My daughter is mostly toilet trained. She is really good at weeing on the toilet at home and when we're out and stays dry. However she poos in her underwear if I don't catch her on time and she won't say she needs a poo. But if her bottom half is naked, she will run to the toilet, sit on it and poo all by herself. I dont understand it haha! I can't just leave her half naked all the time. How do I get her to learn that she doesn't just poo in her underwear?
