Best Children's Book of 2024
Format: Hardcover, Format: Hardcover
My bibliophile kids (11 and 8) and I adore this book. The illustrations are delightfully inviting, the children are magically independent and loving, and the story encapsulates the gentle chaos of childhood in such a beautiful way. Highly recommend.

Great book!
Format: Hardcover
I hate when my kids make messes so this was the perfect book for me. It put things in perspective that messes aren't always a bad thing.

Must Have Book
Format: Hardcover
We purchased this book after having read a New York Times article on the author-illustrator. Loren Long. What an amazing book! I love the story line and the beautifully illustrated pages. Our 7 year old grandson doesn't tire of "reading" the pictures along with the story. The illustrations are loaded with subjects to talk about, along with the peaceful refrain that repeats throughout the book, "And they filled her with joy." This book fills us with joy. Thanks, Loren Long. Another great children's book.

Unique book- creative story and pictures
Format: Hardcover
Absolutely love the black and white pictures with the yellow accents. This is a fun creative book. Perfect for my son who is obsessed with busses and the color yellow. Made from thick high quality materials. Great for young children to enjoy.
