“After work, I don’t always have the energy to convince my son to put the tablet down. I left this book on the kitchen counter, and he picked it up on his own. Now he comes running over to tell me the weird facts he’s learned.”

“I originally bought it as something extra for our homeschool shelf, but my kids don’t treat it like schoolwork at all. They flip through it during breaks and end up researching the questions they find most interesting.”

“When my granddaughter comes over, she usually asks for cartoons within five minutes. The first time I showed her this book, we sat together on the sofa and kept saying ‘just one more question.’ It’s become our little tradition.”

“I’m usually the uncle who buys noisy toys, so I wasn’t sure how a book would go over. Ten minutes after opening it, all three boys were crowded around arguing over which question to read next. That was a win.”
