Totally agree not to push. She isn't even 2 hun. They know when they are ready. They are smart little creatures. My DS was still poo-ing in his nappies when he was going to 3yo kinder. My DD however has been toilet trained since she was about 15 months. She still wears nappies during sleep JIC, but think she'll be out of night nappies soon too.

My point is all kids are different. Don't rush her, you'll end up scaring her probably. A day will come when she'll not want to wear nappies and then you will know the time has come.
