One year old loved the animal sounds
Format: Board book
It only took a few moments for our grandchild to figure out this book. He had a big grin on his face listening to the realistic sounds.

Dead batteries
Format: Board book
The book itself is nice but it came with dead batteries. Now I have to buy and replace the batteries before I can give it as a gift to a toddler who loves pushing the buttons. If not for that, would have given it 5 stars. But the inconvenience of finding the batteries in the first place when I shouldn’t have to is extremely annoying.
