"When I Grow Up" is meant for children and adults to read together. The book is designed to help children learn to read and develop early career aspirations. It's designed to help children understand various job occupations and the responsibilities that accompany them in a way that is fun and creative. There's also space at the end of the book that provides an opportunity for children to think of, draw, and describe other occupations they could hold as adults - outside of those covered in the book. This encourages imagination and creativity while getting them to think about their future.
