27 months is the recommended time to train a girl. Your daughter may be a little young to be trained, though it is worth the try. When are you moving? that will be a big change for her and you may find that she will regress after the move. You may want to wait.

I used the method with the doll with my daughter at 28 months. She had a doll and a special potty for the doll. She was doing really well with the peeing but not at all with the pooping. She is now 30 months, and we are back in diapers because I was tired of cleaning the poop out of her underwear. I decided to back off and try again in a few weeks. It is not as easy as it sounds, and I spent years as a pediatric nurse pracitioner givng parents advice on how to potty train. Who knew.

Good luck
