I usually lurk but do post some lately. I received a letter to be in a book exchange from some of us on one of the Facebook groups.
This is how it works: I have to send a book to one child that is at the top of my list. Then I send the letter to 6 people and add my baby's name to the bottom. If everyone participates the LOs will get a lot of books!!! If anyone would like to participate you can PM me your address and I will send a letter.
