Since Maddie was very small, we would give her an envelope when she lost a tooth and let her write a message to the Tooth Fairy on it and place the tooth inside. When she was young she had questions and requests for the TF (please write me back!), but now that she is older and in the know, things are a bit different...
In case you can't read it easily, it says:
Fairly large tooth. Mild roots. Unbrushed (lingering morning breath). Poor child was sick when she yanked it. Very painful. $3.01
Yes, she sent us a bill for the tooth. Although I have to say that I found her message so hilarious that I pad the fee for the comedic value alone.
