Ali, yes, we did floss our kids' teeth for about one week each, which was enough time to:
1. teach them to do it themselves.
2. realize there was no way in hell we were going to keep doing it.
Two things helped. First were floss sticks, so they could understand how it was supposed to feel and to do more easily while their gums got accustomed to the floss and stopped bleeding every time. And second was tag team flossing. We took turns.
Best angle we found was to stand behind the boys in front of the bathroom mirror and make like we were flossing our own teeth, with fingers in their mouths, of course.
We wasted a ton of floss at first, but then they got the hang of it. One of our boys still uses like three yards of floss every time, but he buys his own now, so that his problem!
How old is T now?
