As an SLP I love this simple engaging book
Format: Board book
Speech path here. I love this book. It was one of my son’s favorites and what I used to help him produce more words from 1-2years. He was my slowest to talk but loved the engaging sounds in this book. It’s simple but you can add a lot of info or new comments each time you read it with encouragement for your kiddo to produce simple early developing sounds. I utilized pausing with it too to tie my son the chance to produce the sounds. I gift it often now! Just wish it was a tadddd cheaper.

Fun and interactive.
Format: Board book
My one-year-old granddaughter loves this little book. There's no story, but it's interactive and fun, and the illustrations are cute and colorful. She enjoys doing all the things on the pages - knocking, waving, blowing, etc.

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.
