Yeap I googled it and found that you can have tooth Fairy pillows. So I made one.
I will save you from a picture of the tooth. It did however work a treat. She didn't let her tooth out of her sight from the moment it fell out so I was scared that she would hang onto it all night and the tooth fairy would not be able to find it and retrieve it. I did convince her to put it in the cushion's pocket and she slept on it.
Much easier to retrieve the tooth in the night using the pillow
