Written by a pediatrician, the Dr. Hippo book series teaches kids about common childhood illnesses like ear infections, colds and sore throats. Each story features a friendly animal family that is affected by one of the illnesses and goes to the reassuring Dr. Hippo for help. The stories are written so that kids learn how they can keep themselves from getting sick and that doctors are friendly people who just want to help them get better. The Dr. Hippo books also include a Parent’s Guide with common questions about the illness featured in the story.
— Guessing All the Way’s Laurie reports that the books were popular with her kids, even inspiring her nephew to share what he had learned with his friends. Laurie cites the laminated Parent Guide as the book’s best feature.
—    Alexandra from Design Baby praised the books as “a wonderful way for kids to absorb knowledge about common illnesses.” Her kids were captivated by the books, especially “The Moose with Loose Poops.” She concluded by vowing that “the next time one of my kids do face one of these five illnesses, I'll be pulling out the appropriate book to soothe their fears, and remind them what is happening, and that this too will pass.”
