K.D.
Just make her do it....take the diapers away and deal with the mess for a couple of days....she is old enough, you are not dealing with a child who is too young to understand. I found with both my kids, it really wasn't about them, it was about me....when I finally put my foot down they were fully trained in a couple of days. You always hear, you shouldn't push them, but I don't agree...I tried the don't push approach for 6 months with both my kids (nope, I didn't learn the first time!!) Once I was ready, they were trained. A little tough love won't scar her!! Good luck!!
