If your grandchild is interested in a specific animal, help him learn about it. Many people who have an interest in birds, create a life list of every species they see, and travel around the world to grow their list. Helping your grandkid keep a list may help develop an intense interest for insects, birds, butterflies, or something else. It may even lead to a career as a biologist, such as the American biologist, naturalist, and writer, E.O.Wilson, who specializes in the study of ants.
