Riley lost their very first tooth and put it under their pillow for the tooth fairy.
Is the tooth fairy going to come tonight? Only if you put your tooth under your pillow! Ok.  I just did that.  How long do I have to wait? You are just supposed to fall asleep as usually.  It only comes when you are sleeping and will disappear if you wake up on it! So I'll have my gift in the morning? Yes.  Look under your pillow when you wake up.
