This Tooth Fairy panicked too, not knowing what to do or what to tell him. What's the proper etiquette? We decided the tooth fairy must be a reasonable being and that a polite note (see above) would do the trick. So when my tot awoke the next morning, not only did he find a few gold coins and a smattering of fairy dust, but also, his baby tooth was still safely tucked away in the pillow. But the experience has me wondering what other Tooth Fairies do.
