What You Need to Know

At 2 months, babies start to show signs of increased alertness and social engagement. According to the American Academy of Pediatrics (AAP), this is a time when babies begin to smile socially, indicating early social development. They may also start cooing and gurgling, which are precursors to verbal communication.

Evidence-Based Guidelines

According to the Centers for Disease Control and Prevention (CDC), 2-month-old babies often begin to track objects with their eyes and respond to sounds. The CDC recommends engaging with your baby to support these developments. The World Health Organization (WHO) advises monitoring your baby's auditory responses and encourages interactive play to promote cognitive and motor skills.
