take her to the bathroom with you every time. i started this with my daughter when she was 6 months. explain the whole process. tell her step by step what you are doing. show her what it means to go pee pee. if she is still reluctant, then you may want to back off. most times kids will let you know when they are ready. at 18 months my daughter took a parents guide to potty training out of the elmo's dvd case, and walked straight into the bathroom. she ordered me to sit on the big potty while she undressed herself, and sat on hers. she then handed me the guide, and said, "here, mama. you read now! teach me." then she opened it up for me, and turned the pages. i knew at that point she was ready. however, every child is different, and everyone learns at their own time and pace. don't force her into it. this will only make it harder to train her, and she will end up refusing.
