Ever since Mira got her first teeth I've been "brushing" her teeth with a washcloth wrapped over my finger. We do it after every solid food meal, as part of the clean up procedure (2 to 3 times a day). She's actually really good about it. She'll open her mouth for it and sometimes she giggles while I'm brushing. Only thing is, every time I try to get the back side of her top teeth it's like I trigger a reflex or something and she bites down. I'm not really sure how to get her to stop doing it and keep her mouth open. I try making open-mouth faces at her to demonstrate, and saying "Say AAAHHH" like they do in the doctor's office. But that doesn't seem to work. I can get her to open her mouth by putting my finger on the tip of her chin, but then when I put the "brush" back behind her front teeth CHOMP. It may just be one of those things that will have to wait till she can understand what I'm saying a little better, but if anyone has any tips or tricks, let me know.
