My DD is 2, and was a preemie meaning 1) she is at a higher risk for cavities due to potential issues with mineralization/ poor calcium levels when she was a newborn/ should have still been gestating, and 2) she has an oral aversion from being incubated, etc and really needs to be in control over her mouth. I've also seen how forcing something over and over can maybe make a kid used to it but also can maybe make an aversion worse. So, she is always happy to brush her own teeth but if I wanted to help her, it would require restraining her and prying her mouth open with some instrument and brushing. Which I'm not willing to do. So, fingers crossed. I am a great teeth brushed and flossed myself, and I will feel really embarrassed if she gets cavities, but I don't know a better alternative.
