Hello, World! is a series designed to help parents introduce simple nonfiction concepts to their babies and toddlers. Now even the youngest children can enjoy learning about the world around them. Told in simple terms and accompanied by bright, cheerful illustrations, Hello, World! makes learning easy for young children and offers useful prompts to the adult reader in order to help them engage with their child on each page.

Each book in the Hello, World! series covers a different topic—from animals and plants to weather and seasons—and follows a similar format: an introduction or "hello" that explains what's coming up next; then a few pages of simple facts ("Peck, peck, peck! This noisy woodpecker is looking for food inside a tree trunk."); followed by another "hello" and some questions to think about or answer together; followed by more facts; and finally an activity page that involves using all the information from earlier pages together in one fun activity ("Find three birds you can see together outside today."). It's like your child's own little science book! It's a perfect way to bring the outside world of natural science into the busy world of a toddler, where learning never stops!
