Your Child is smiling back. This is not only one of the most beautiful things in the world for new parents, but also, it indicates that Your Child is learning a nonverbal way to communicate.
Smiling responsively usually happens at around 2 months of age. It shows that Your Child has started to observe and mimic human behavior and is grasping the concept of expressing comfort, seeking attention, and making contact with others.
How to support this development
Smile at Your Child often, and greet the little one with a high-pitched, playful voice. Make sure your face is close to Your Child whenever you smile since babies at this age see best at about 20 centimeters away.
Note: All children develop differently and at their own pace. For children born preterm, the referred timeframe for achieving the various developmental milestones might be incorrect.
Sources: The information and graphs about when children reach specific milestones are taken from various sources, including the United States Center for Disease Control (CDC), the Denver Developmental Screening Test, and the State Institute of Early Childhood Research, Germany (IFP).
