brushing teeth,
at my own home, i'm still using first teeth and finger brush. i don't brush at the sink, will brush wherever kaizer is (on highchair, on bed, during bathtime etc). i will scrape his tongue with the finger brush also, so he hates it, even though he allows me to do it. no gurgling/rinsing at the sink, but i'll get him to take in plain water using a cup after brushing.
at my mum's home, she brushes for him using first teeth and kid's brush at the sink. then followed on by gugling and spitting, which he actually can do quite well.
i find that brushing is not very clean though, so besides finger brushing, i also floss his lower teeth daily with a floss pick. there's ALWAYS remnants of meat whenever i floss. sometimes if he's in a restive mood, he will allow me to floss the top teeth and inner molars, otherwise he only allows me to floss the bottom 4-6 teeth and that's it.
