Great interactive book for Littles
Format: Board book
This book is so cute and very interacting. Some of the pages are a little confusing on how we are supposed to react, but overall it’s a great book. The beginning has some instructions and tips to help your little speak so that is very helpful.

A Must-Have First Words Book for Toddlers
Format: Board book
As a parent, finding tools that truly helps your child’s development can feel overwhelming, but this book is one of those rare finds that actually delivers! What sets this book apart is how naturally it encourages imitation. It’s doesn’t feel clinical or intimidating, it feels like play which is how children learn best!! Knowing this book was created by a pediatric speech therapist and mom gave me total confidence in using it. The sturdy board book design is perfect for little hands! I highly recommend this book!
