P.Z.
My daughter started doing the same thing @ 18 mo. I was sooooo excited! She waivered back and forth, and finally trained ...@ 2 1/2. It's frustrating, but if you're able to be very consistant (I was not). and take her to the potty, she may train! If not...not. Sooner or later they all do!!! Just be patient. It is possible she trains first, girls tend to, I guess. My pediatrician said she had only seen 1 trained by 18 mo., and it was a girl. A co-worker of mine said she had her girls (3) all trained by 12 mo.!!! They are all grown now. Amazing! Good luck!
