I say DS because DD is fine and I sense this is a boy thing.
I know when I have not brushed my teeth. My entire being shrieks: "Where's the fur-free shiney feeling? Where's the minty freshness?" I could no more leave the house in the morning without brushing my teeth than I could without putting any clothes on, emergency excluded (in both cases).
DD seems to have "got it" and brushes her teeth twice a day, no problem.
DS1 (1.5 years older) is a different matter. EVERY day, I have to say (morning or evening) "Have you brushed your teeth?"
A look of intense, not unintelligent, perplexity crosses his handsome face. I am convinced his thoughts run thus:
"Teeth. Teeth? Teeth! Mammals have teeth. They use them to bite. I am a mammal! I have teeth. Yes. Those are the things in my mouth that are white-ish yet not as white as those in my sister's mouth. I wonder why? I digress . . . have I cleaned my teeth? Why would I clean them? Why would they need cleaning? What would I clean them with anyway? Some sort of brush I suppose . . . WAIT!!! . . . Someone gave me a little brush for Christmas, ahhh perhaps that's it. Have I used it today?, hmm, it's hard to think with Mummy yelling at me FOR THE LOVE OF GOD DS1 ANSWER ME. Now she is stamping upstairs to "feel my toothbrush" - she is one weiiiiiird woman."
DH brushes his teeth.
Every grown man I know brushes his teeth.
Please tell me at what age the switch clicks and they start to do it by themselves?
Please don't tell me it's 13, when they want a snog. That means I have another 4 years of this...
