Development of a 2-Month-Old

By Bridget Coila ; Updated June 13, 2017

Babies seem to grow quickly in the early months, and parents sometimes feel like they are seeing changes every day as their infant learns new ways of interacting with the world. A 2-month-old baby is past the stage of being a newborn and has begun to develop his own little personality and interests as well as growing physically.

Physical Development

A 2-month-old baby's physical development skyrockets. He will continue gaining weight and growing in length and head circumference, which the pediatrician will measure at each well-baby appointment. With this growth also comes stronger muscles, making a 2-month-old quite squirmy. However, his once jerky movements will start to smooth out at this point and his ability to lift his head up is improving. A baby this age might also be starting to roll over.


Babies at 2 months old start to pay more attention to the world around them. A 2-month-old's eyesight has improved significantly since birth, so now he's able to see objects in greater detail. This leads to an increased interest in new visual objects and he'll be fascinated by colors, shapes and patterns. Hearing is another sense that has improved by the second month, causing baby to turn his head toward familiar voices. He also loves to hear his parent's voices and will be particularly attentive when he hears them singing or reading aloud to him.


A 2-month-old baby starts to communicate with those around him. Before this point, his only method of communicating his needs was to cry. Now he can also smile, coo and make other sounds and expressions that indicate if he's happy, sad or frustrated. Toward the end of the second month, a baby may even begin to laugh aloud.


Some babies become fussier around the age of 2 months. This may be a result of colic, gas or other physical issues, or it may just be a result of the baby being able to express himself better about little things that bother him. On the flip side, babies also become more attentive and alert during the second month, spending a lot of time in a quiet, alert state where he looks around and interacts with his caregivers.


All babies develop a little differently and particular milestones may occur for a particular baby before or after the 2-month mark. Some things that parents can do to encourage a baby to meet his 2-month milestones include giving him tummy time and encouraging his vocalizations by talking back or mimicking the sounds he makes.
