Look Ma, no teeth!

Hopefully, you've already guessed what this post is about, and you're rounding up those toothbrushes.
I know.  Just try looking behind the sofa, in the freezer, the sock drawer,,,all the usual places.
Let's try not to double up on this...most children, at least by age 12, catch on that it's not normal to share their siblings toothbrush.
And no, I am NOT suggesting that you go and by everyone their own.  As in, their own to lose, their own to end up getting used as a scrub brush when the ajax runs out, or the brillo...okay, those days are over.
'Cuz, today, we have a plan.  You see that cord on the end of your phone (I already know that you don't have a cordless phone, or if you do, it's beeping too mildly to locate--try the laundry pile--one of them)
That's the kind of cord you want.
Try looking for an old slinky, if other options fail.
Also, bungie cords work great for this.
Now that you have your cord, it's time to drop anchor.
I recommend attatching the bungie to the window sill over the kitchen sink.
I know, it's ideal to brush the kids teeth in the bathroom.
This is great, if they are over seven, and don't resist.
For all others, I recommend the following strategies:
Bribe
Catch, and
Tackle.  Tickling is a fairly effective way of getting your toddlers mouth open.  Once they're laughing, they usually comply.
Kitchen counters aren't effective "operating' stations for squirmers.
Truth be told, bunking them down, sleepy eyed, and brushing dry is better than nothing.  Slather them with fluoride in the morning.
