Hello. My eldest daughter is 3 years old and I've stopped her from using diapers. She constantly told me she wanted to go potty, both small and big, but for the last couple of months she has stopped saying anything when she wants to go big, only then does she say she wants in the toilet, and doesn't say anything about going small, she does her business, already I have to take the carpets to the cleaning service, etc. We started wearing pull-ups again. Help please. Why did she stop peeing like this?
