Educational book loved by older infants and toddlers
Format: Board book
Such a cute book. I got one for each grandchild and they both love it. They are so cute mimicking animal sounds and they adore pushing the sound buttons.

Amazing product!
Format: Board book
LOVE this book for my baby. The buttons are very sensitive and responds to a light touch which means that my baby can actually push the buttons with positive feedback. Wish they had more books like this! (Only thing that I would consider changing on this book is an on/off toggle for the sound)
