Great
Format: Paperback
We love these books for our travels with kiddos. Keep them in our backpack and they always have something to do when we are stuck waiting somewhere. So much great info in these books!

Weird printing error
Format: Paperback, Format: Paperback
There are about 30 pages in the middle of the book dedicated to “what is special about dad”. I have to imagine we’re missing quite a bit of the actual book.

Great series
Format: Hardcover
The Worst is a great series. I ordered them for my 3 year old granddaughter, and they’re her favorite. She has all except the newest one, which I will be ordering for her birthday.

Great quality, good content
Format: Hardcover
“The Worst” series is actually… the best! It has become tradition to get my little brother one of these books every Christmas. It has been fun for everyone whether reading or listening. Can’t recommend enough!
