The premise is that kids are supposed to rinse with this mouthwash before brushing their teeth. It leaves a blue coating where plaque has accumulated so the kids know where to scrub hardest. Eldest can do it correctly on his own. He fills the cup to the line and then gargles for 30 seconds. Middle? Not so much. He completely swallows it, but it still manages to leave a nice blue ring around his mouth. And I'm not letting Baby anywhere near the stuff. I suspect if I did, he would instantly transform himself into a Smurf.
I only let the boyz use it right before bedtime, so since the novelty hasn't (yet) worn off, they actually get psyched when it's time to go upstairs for teeth and bed. You know what? For $3.99, it's soooooo worth it. This is not a paid advertisement for the stuff, but it should be, huh? If you'll excuse me, I need to go now so I can contact Listerine to become their new spokes
