Every week with me at home she’s fully trained wearing undies. Every Thursday and Friday she goes to childcare and will wee and poo undies there so is expected to wear a pullup… Which she wees in. At Home she never wets her pants. Then come Saturday I’m back to getting her back into undies and she forgets she’s in undies and has regressed…by Sunday she’s right again. It’s a nightmare and I’m over it. If I was at home with her full time she would be fully trained by now.
