Babies! — Dorothy Hinshaw Patent

Published by Holiday House, 1988.

Most babies don't smile until they're about 4 months old. Smiling is an early form of communication, like a baby's cry. This book has full-color photographs of babies from newborn to 2 years old. It explains how a baby grows and changes and tells about when a baby reaches important milestones, such as learning to talk and walk. It also describes games babies like to play—from peekaboo to rattling pots and pans.
