It depends on if the Tooth Fairy makes it to the house on the first night that the tooth comes out. Sometimes he gets so busy and backed up that he doesn't make it to Ohio on that first night. Sometimes not on the 2nd night. And did you know that for each night he doesn't make it, the $ goes up?
It got all the way up to $20 one time. We just assumed he got lost often because our home is sort of hard to find.
(We kept forgetting! Adding on the cash was the only way to quiet the wailing and gnashing of teeth that ensued in the morning.)
