We're working on it yet again and there's no going back. We started yesterday around noon and Isabella has yet to have an accident!!! (She did wear a diaper at night though). She is doing great although I think my questioning whether she needs to go every ten minutes is driving her nuts (she has even told me so). So I am trying not to pester her very often and wait till she asks to go. I'm so proud of her!
UPDATE: she just pooped in the toilet too! YEEHAW!
