A Favorite!
Format: Board book
Having loved Richard Scarry books as a child in the 70's, I was thrilled when he regained popularity in the 90's when we were raising our children. Now I get to share this beloved classic with my granddaughter. She LOVES her Richard Scarry books and this one is wonderful. Every page has so many beautifully illustrated details so there are always new things to look at and discover. She is 18 months old and the Richard Scarry books have been instrumental in helping her vocabulary, now over 200 words. Highly recommend that you add this awesome book to your baby's library and read, read, read to your baby every chance you get!

Time tested classics for children

Love Richard Scarry books for toddlers and above!
The board books are great for younger ones—kids are enthralled by the illustrations—-parents by the educational content. Classics!

A great way to start makes adding more a breeze.
Format: Board book
As soon as words you want to teach gain clarity, sentences will follow faster. The little “sponge”takes communication seriously. Add a motion to the word and it will be remembered longer, and used in 3-word sentences, etc. the first 100 words will double then triple surprisingly fast.

Necessary book for little ones!

Great baby gift. My grown children loved Richard Scarry books. My daughter asked for this as a baby shower gift. Her son I'm sure will love it as much as she did.
