My daughter was totally potty trained in July. Then she went back to day care in September. By October, she started having accidents. She would poop in her pants sometimes, but she would frequently have small streaks of poop in her underwear. Then it was becoming more and more to the point she is totally back in pull ups now. I had her to her doctor and he felt she was just being stubborn and told me to just stick with it. She is still doing it, she is getting awful rashes on her bum from having small streaks of poop on her bum and from being cleaned so much. And now the daycare told me she had a really fishy smelling poop. Is this normal or should I make another appointment with her doctor?
