Acclaimed New York Times best-selling author Robie H. Harris introduces preschool children to the pleasures of eating healthily, being active and feeling good. Gus, Nellie and baby Jake can't wait to go on a picnic! In the morning the family heads to their community garden, then to the farmer's market and the supermarket to gather vegetables, fruit, meat and other fresh and delicious foods. Readers follow them through the day as they go home to prepare, cook and pack up the goodies. The book ends with the family eating a yummy meal in the park and flying a kite together. Funny, accessible, family-filled illustrations, conversations between Gus and Nellie and a matter-of-fact text combine to show young children how food fuels our bodies - and help them see how healthy eating and drinking, and being active, can make them feel their best for a day full of fun.
