Optimal Quality
Format: Board book
This book is sturdy, colorful and cute. The baby likes it, so we are happy we got it. The whole collection is worthwhile, and is very well designed for little hands. The baby is now 18 mo old.

Lazy quality
Format: Board book
My book came with a big, ugly, torn off sticker across the front. We collect the Babies Love books for our baby and I just really did not appreciate the ugliness of the outer cover. Seems like laziness to not remove that before sending it to a paying customer.

Just ok
Format: Board book
Love the concept of teaching baby kindness. The words in this one miss the mark unfortunately. This is not one of our favorites.
