Re: Is she trying to potty train?
I would say she definitely is trying to tell you she is ready. My son potty trained himself at 19 months. He saw some thomas the train underwear at at target and fell in love. Didn't want to wear diapers anymore! We came home with 1 package of undies thinking he would change his mind. He had a couple accidents the first day. One accident the next day and that was it! Choo Choo undies ever since (except at night time)
I hadn't expected him to potty train before I had my ds#3, but he sure did. I followed his lead and boy has it helped me out!
Good luck mama and to your dd!
