Do you ever worry about your kid's dental health? I am a total freak about cleaning her teeth, I really worry about the possibility of her ending up with my teeth, and so she gets brushed three or four times a day.

I don't get freaked out about it but I also don't let it go either. My kids brush twice a day. They seem to have teeth like mine. My teeth get very few cavities, even when I forget to brush more than once a day. I aim for two but sometimes life, and my kids, get away from me.
I also think that you can never brush too much though. If you're going to worry if you don't brush them, then go ahead. It'll teach her to keep her pealy whites, white.

I shudder when I see kids with rotten teeth, sometimes it pretty hard on the parents too because they do try. I try my best to keep my son teeth clean, apart from the fact that he doesn't have candy or much sweet stuff.
