Are tooth fairy rates rising or not? Depends on what's in your wallet

I have, as a parent and tooth fairy, been a victim of late bedtimes. By the time I've gotten my now-seven-year-old and his little brothers to sleep on the nights he's lost a tooth, then had time to decompress and think about it, it's been far too late to go out and get change.

While some other parents I know pull out their tooth fairy rule book (look under "e" for "excuses") and find that obscure caveat about the fairy's schedule -- any teeth discovered to have been lost after 5 p.m. will have to wait for payment until the following evening -- I simply rifle through my wallet and the bottoms of my bags and pockets until I assemble a serviceable assortment of coins and dollars.
