Why Don’t Your Eyelashes Grow?

Why Don’t Your Eyelashes Grow?: Curious Questions Kids Ask About the Human Body by Beth Ann Ditkoff M.D. is filled with fun trivia and answers to questions kids sometimes ask about their bodies, like what their Adam’s Apple is for and why ears are filled with earwax. There’s also an “Urban Myth” section that covers typical parental warnings like whether it’s really bad to crack your knuckles or if you’ll actually see better if you eat carrots.

Ditkoff wrote this book with the help of her two daughters, and explains in the introduction that these are also questions she gets from her patients as well as family and friends. At only $5.98, this is a great stocking stuffer for kids who like trivia books.
