my daughter is 22m now. she refuses to wear diapers and only will wear pullups. she knows what pee pee is and what poo poo is, she has a potty and went pee in it two weeks ago for two days in a row. but since then she refuses to go in the potty! she tells me after she goes pee in her pullup and after she goes poo in her pullup too (sometimes apx 20mins before she has to go poo). i do ask her and take her to sit on her potty, but she refuses to go, sometimes getting up and playing, or tries to stand on her head..i'm so frusterated! and pullups are so expensive! is she just not ready? where am i going wrong and how can i get her to go in the potty!?
