I've told other moms this and it works with all of them. Hopefully for you too. I had a small chat with my daughter about bugs and germs and how they are on our shoes, hands, and even in our mouth. Then, the same night but well after our germ/bug talk...we started to brush her teeth and I said loudly, excited and a little disgusted, "There's a buggie in your mouth...Gross! Hopefully he doesn't poop in your mouth...yuk! We should brush your teeth to get that buggie." So, we brush and we chase that buggie all around her teeth. Sometimes he is slow and easy to catch, and sometimes he's fast and goes all around the mouth and we chase him...or he's a jumper and hops all over from top to bottom, or he's hiding. We finally "Catch" him and we wash him or spit him down the sink. Then, when we're done, I smell her breath and tell her how wonderful her breath smells and that I don't smell buggie poopoo anymore. She is almost 3 and we still do that...it's a little game we can play together, even though she is old enough to know there aren't bugs in her mouth...it's still fun and keeps her interested. Little does she know...there ARE buggies in her mouth. HAHA! She really likes our game. She'll even say, "I see a buggie...I better get him!" She chases him around with her toothbrush. She'll even point to her brush and say, "I got him...see him", even though there isn't a bug there. You get the idea...make it fun. She'll catch on soon. Good luck. Hopefully, this works for you as well as it's worked for us.
