Brushing Teeth

I got this toothbrush for her a few months ago. But, the two teeth that she has weren't even all the way out yet. I noticed the other day that they are all the way out now. She doesn't really brush them. She mostly chews on the bristles. For some reason she likes the way the baby toothpaste tastes. I tasted it to see what it was like and it's disguisting.
