Greenfield has written numerous works, the first one dating back to 1972 with her piece called Bubbles. She writes poetry, picture books, board books for young children, intermediate books and some biographies. One she wrote with her mother was called, Childtimes, which was a biographical piece about three generations of her family. It includes a section about her grandmother, then her mother, then of course, herself. It was written in 1979.
Green field writes about everyday situations in the lives of African American children.
However, some books, deal with themes such as divorce, dreams, music, sibling rivalry, and bonds between family members. She has been noted for writing well in the voice of a child. She publishes her work mostly through African American companies. Other times, I feel a kind of pain in struggling to find the right ones. This book is a board book for very young readers.
