The Official 'lil Fairy Door Store: 

How it works: 

Attach your special little fairy door low on a wall, high on a shelf or outside on a tree... 
Once your 'lil Fairy Door is attached, the fairies will know how to use it to come in and out. 

They only come out at night and are sometimes known to exchange notes and gifts with their children friends... 

Rewarding good behaviour:

Helping children through difficult childhood stages... sleeping through the night, potty training, moving schools or to a new home. Learning how to read. Separations or loss. 

"The Fairies" from time to time, can leave notes of encouragement for good behaviour, special gifts & rewards to show they've been watching. Sometimes the fairies might even sneak through your 'lil Fairy Door and play with some of the toys in your room, leaving little footprints of Fairy Dust behind.
