What families tell us
12,500 reviews, rated 4.8 out of 5 by parents and grandparents.
He reads it at breakfast
My seven year old used to need reminders to read. Now the book sits open next to his cereal bowl. Last week he explained to me why the moon looks bigger near the horizon.
Questions got harder
We bought it for our daughter's ninth birthday. Two months in, her questions changed from what is that to how does that actually work. The answers are short enough that she does not lose interest.
Great gift, heavy book
Bought two, one for each nephew. The hardcover packaging meant no wrapping needed. It is heavier than I expected, so it stays on the desk rather than going in a backpack, but they use it daily.
