My daughter is 2 and we need to start potting training. sometimes she tells me when she has to poop but never when she has to pee. She has yet to pee in the potty. she has woken up from naps a few times in past week dry so I put her on the potty but she wont go. of course as soon as I put a diaper on her she goes...not sure what to do. Maybe she isnt ready?
