Simple learning book with lots to offer!
Format: Board book
I really love rainbows and I wanted to share that love with my children. This book is a great way to do that! It has solid construction with clean soft cuts on the pages, which are thinner but just as sturdy as most board books. Not too short, and well illustrated, and a good introduction to the colors, it is well worth the price.

Love the message the story tells, easy read!
Format: Board book, Format: Board book
This book tells a perfect little story teaching little ones to be thankful. I love how it only tells a story about being thankful and kind, but it also is teaching them numbers through repetition. Each page shows a number and also has the word of the number to read. In such a short read, little ones can learn a lot. Because it’s short and sweet, it keeps their attention and the illustrations are cute and fun for toddlers to follow along with. This makes for a perfect gift for a new little one or a great addition to a current toddler library! In our family, we also love that it’s a board book Because it holds up longer with a family of three little ages 1, 2.5 and 4. Everyone enjoys it and it’s a family favorite!
