Molly Wants More! by JoDee McConnaughhay

Molly Wants More!, written by JoDee McConnaughhay and illustrated by Sheila Lucas, is a Happy Day book by Standard Publishing

When Molly eats all the cookies instead of sharing them with her little brother, her mother has a chat with her about the more bug.  Molly doesn't like bugs and wants to get rid of it.  Her mother tells her that she can get rid of the more bug by repeating Psalm 23:1 "The Lord is my Shepherd, I have everything I need."

We borrowed this book from a friend and we weren't long into the book before Anna was repeating the verse and discussing times when she could say the verse to help her not want more.
