How to Make a Monster Smile (aka the happy book) is the book to grab when your little one has turned into a little monster. It is the book to grab when it's two hours past nap time and you just served your child's favorite snack in their least favorite color of bowl. It is a parent's go-to, when it's your fault the sun is too bright, or a tag is too itchy. We can attest to a 100% monster-smile success rate.
