This primer, part of the Brilliant Baby series, prepares little ones for the insidious, ever-present threat of germs. Each two-page spread contains a short rhyming couplet, the text beginning with the nature of germs ("too small to see," "make you sick," "spread from one friend to another") and turning to safety practices that every person should employ ("keep your hands clean," "cover your sneezes," "[sleep] enough"). The book also takes a pro-science stance, showing scientists working to find cures, recommending that kids "get all [their] vaccines," and showing images of people wearing face masks. A timely introduction to smart, healthy habits.
