The tooth fairy's a no-show Help your child search for her reward, and while you're doing it, slip the gift into the pillowcase. Or, when your child goes to the bathroom, quickly stash the cash; when she comes out, say "Are you sure you looked hard enough?" (Trust us -- it works every time.)
Your child can't find the lost tooth and it's time for bed Have her make a paper tooth for under the pillow instead, or write the tooth fairy a note explaining what happened. (Note to fairy: It's really fun if you write back!)
Inflation puts your tooth fairy under pressure Talk to friends' parents and agree on a set rate. Or consider leaving another type of treasure under the pillow, like a small toy from the dollar store.
