I know that you may think that your child is not ready to be potty trained, but she is. She is going on two years old and should not be in diapers unless there is a medical condition for it. You will have to be persistent and consistent in helping her. She may not necessarily want to use the potty, but may actually want to use the adult toilet. Next time, take her to the bathroom and place her on the toilet. Be patient and give her time. If you do this on a consistent basis, she will become accustomed to doing it on her own and let you know when she has to go. Take it from the mother of several children. When one thing does not work, try something else. And try to understand what the child is saying without saying.
Good luck and remember to be patient!!!
