What is a typical behavior of a three-month-old infant?

At three months of age, infants are in a developmental stage where they begin to engage more actively with their environment. One of the typical behaviors during this period is the ability to imitate facial expressions. This imitation demonstrates cognitive development and social interaction skills as infants are starting to engage with caregivers and recognize social cues.

The ability to follow objects with their eyes is also a behavior seen around this age, but it is not as distinct as the imitation of facial expressions, which is more pronounced and indicative of cognitive engagement with others. Other behaviors, such as responding to their name or walking unassisted, occur at later developmental stages, making imitation of facial expressions a key milestone for a three-month-old infant.
