My daughter is almost 3. I have tried every trick in the book to get her to go on the potty. If you ask her stuff like where we pee or poop she responds potty, but she will not use it. If you try to put her on the potty she screams no. I have her in underwear for the last day and she uses the underwear like a diaper and just pees in them. I don't know what to do. Can anyone help?
