Why is the sky blue? Why do I have to sleep? Why do the birds sing? Why do I have to go to the toilet? A walk in the park, taking a bath, helping mom in the kitchen... with all activities, a child asks a thousand and one questions. In this first question and answer book, many mysteries are unraveled in a clear and simple way. Your child will learn everything about the how and why of what happens at home, in nature, in the supermarket or on the farm. Catherine Ripley is an expert at answering children's questions. While working as an editor of a children's magazine, she began collecting questions from young readers. She visited schools and libraries and focused on making science fun and understandable for children. Catherine has several successful children's books to her name.
