Baby books started appearing more frequently in homes in the 1910s but gained popularity in the succeeding decades.
[1] Baby books can track a child's development or mark developmental milestones.
Some books are pre-fabricated with fill-in-the-blank areas and places to put special mementoes, such as a lock of hair from the baby's first haircut, a hospital bracelet, birth announcements, or cards from the baby shower.
UCLA has a collection of baby books dating back to 1882 used for the study of the history of childhood, family, art, medicine, architecture, and other disciplines.
