In a cheery book for toddlers—one of four titles launching the My Little Planet series—three children welcome spring by planting a seed. “This small hole is all I need./ Now some water./ Now some sun./ Planting seeds is so much fun!” Every natural and inanimate object seems to come alive in Jatkowska’s joyful pictures, as the trio nurtures the little plant. The chipper verse and bright palette offer an enthusiastic endorsement of the joys and small miracles to be found outdoors. Simultaneously available: Pick Up the Park, Recycling Is Fun, and We Need Water. Ages 2–4. Illustrator’s agent: The Bright Agency. (Feb.)
