My son is the same way. He's 21 months old and he tries to brush his teeth the best he can, but I know he's not doing the best job, but he does bite the brissles so they are getting his teeth. I wouldn't worry about it to much. If she is aleast trying then gradually as she grows she'll learn to get better. I also brush my teeth with my son. He'll usually copy me which guides him in the right direction. I hope it works out.
