Our daughter Maggie was trained just after her second birthday. She was doing great! in underwear all day, except naptime. Naptime and bedtime she wore pullups. then she started having like an accident a day. then it got to be a couple a day. And then she just quit using the potty altogether! I finally quit fighting her and left her alone. She's been in pullups full time for 3 months now. We have a 4.5 yr old, and an 11month old too. She's the only girl. I bought diapers and her pullups today and realized how expensive it was getting and decided to get her back on track. But i'm not sure how to start. she doesn't tell me when she needs to go potty anymore, she used to. she doesn't tell me when she needs to be changed even. She'll sit in a poopy pullup until we figure out its her that stinks! she's very bright and talks well. She knows where the potty is and what its for. She can dress, undress, and pull her pullup up and down by herself. She'll be 3 in june. any advice?
