Fun experience for a new toddler
Format: Board book
There are 6 flaps in total, so 12 pages for the book. Not much to read, but more for the interaction to open those flaps. The edges are rounded, so there shouldn't be any paper cuts for the little one.
With that said, this book is thicker than usual, so it's a little tougher for the baby to flip through the chunky pages. The storyteller would probably enhance the reading of the book. And for now, the little one is saying "booooKK" for the past 3 days, wanting to get her hands on this new book.

Cute little book about kindness
Format: Board book
It's not a story so much as a bunch of kind, polite phrases, but it rhymes and the illustrations are adorable; so, we enjoyed it anyway.
