Great book for learning about Earth
Format: Hardcover
My son was asking different questions about the Earth and this book was the perfect surprise for him. He’s only 5 so he loved all the different interactive features on every page. We read it together and it was just the right amount of information for him to understand. 100% recommend for curious little minds!
