Toddler approved!
Format: Board book
My 2 year old loves this book! The pictures are beautiful, he's learned the names of all of the bugs, and it's a nice small size that's easy to read using one hand with my toddler in my lap before bedtime. I bought this when he was around 18 months old and it is still a hit.

Great book!
Format: Board book
I really like this book it includes: ladybug, bumblebee, praying mantis, firefly and (monarch) butterfly. So a good selection of bugs a small child is likely to experience in their yard or park in North America. For the photo board book aged children I really prefer that they discuss vocabulary that the child will be able to use to describe the world around them so I appreciate that most kids will see most of these bugs fairly easily and frequently. I did question the praying mantis since I see them much less frequently than the other bugs in the book but my husband said it is an exciting bug when kids do see it so he supports the choice--I think a fly or mosquito might have been a somewhat more useful choice as far as vocabulary our son could use most often. I liked that they did say the butterfly was a monarch but typically used butterfly so if a child lives where other butterflies are more common they learned the more general term. I think fireflies are less common in some regions but they are so magical as a small child that I think it is a good choice.

Son loves it
Format: Board book
Sturdy enough for 19 month old. He loved learning about the insects and looking for them outside. I love the real pictures and facts.
