When a child is born, it can be easy for adults to forget just how much these new arrivals have to learn. Starting with a child at home eating lunch, this engaging book for prereaders explores the wider world, including plants and animals, mountains and forests, weather and seasons. The investigations are led by a little girl named Koko who poses instructive questions, and is aided by three intrepid explorers. Brightly illustrated in styles ranging from cartoons to photo collage, the book also contains games, recipes, crafts, and fun facts.
