How old is she - not in years - in months. There is a big difference between 24, 30, and 35 months. A 24 month old may not care about a sticker chart, an older 2 may love it.
And was she ready? If not, you just have to keep taking her at set times until she is ready. Or you can wait until she is ready and then restart.
