By 2 months old, your baby is likely starting to smile at you, track objects with their eyes, make sounds beyond crying, and hold their head up briefly during tummy time. These are the core milestones pediatricians look for at the 2-month well-baby visit, and they signal that your baby’s brain, body, and senses are developing on track.
Social and Emotional Milestones
The biggest crowd-pleaser at 2 months is the social smile. Unlike the reflexive smiles you may have noticed in the newborn stage, your baby now smiles in direct response to you, typically when you talk to them or smile first. This is one of the earliest signs of genuine social interaction.
Other social and emotional milestones the CDC lists for 2 months include calming down when spoken to or picked up, looking at your face, and seeming happy to see you when you walk up. These behaviors show that your baby recognizes you, finds comfort in your presence, and is beginning to form attachment. You might notice your baby staring intently at your face during feedings or quieting when they hear your voice from across the room.
Sounds and Early Communication
At 2 months, babies start making sounds other than crying. You’ll hear cooing, gurgling, and little vowel-like noises (“aah,” “ooh”) that are your baby’s first experiments with their voice. These sounds often happen when your baby is content, especially during face-to-face interaction with you.
Your baby should also react to loud sounds at this age. A sudden noise might make them blink, startle, widen their eyes, or briefly stop moving. This response is a basic but important indicator that their hearing is functioning normally.
Vision and Eye Tracking
A 2-month-old’s vision is still developing, but it’s markedly sharper than at birth. At about 1 month, babies can focus briefly on a face but tend to prefer brightly colored objects up to 3 feet away. By 2 months, a key shift happens: babies can usually follow a moving object with their eyes as their visual coordination improves. This is why the CDC includes “watches you as you move” and “looks at a toy for several seconds” as cognitive milestones for this age.
You can test this casually by slowly moving a colorful toy or your face from side to side while your baby is alert. Their eyes (and sometimes their whole head) should track the movement, at least partway. High-contrast patterns and bright colors are still the easiest things for them to see clearly.
Physical and Motor Skills
Two-month-olds are not yet rolling, reaching, or grasping with purpose, but they’re building the foundation for all of those skills. The most visible physical milestone is improved head control. During tummy time, your baby may lift their head briefly at a 45-degree angle before setting it back down. Their movements are still jerky and uncoordinated, but you’ll notice their arms and legs moving more actively than in the newborn period, with smoother, more varied patterns replacing the tight, flexed newborn posture.
Tummy Time at 2 Months
Tummy time is the main “exercise” for a 2-month-old, and it directly supports head control, neck strength, and eventually rolling and crawling. The NIH recommends that by about 2 months, babies get 15 to 30 minutes of total tummy time per day. That doesn’t need to happen all at once. Two or three short sessions of 3 to 5 minutes work well, and you can add more as your baby tolerates it. Many babies fuss during tummy time at first. Getting down on the floor face-to-face with them or placing a small rolled towel under their chest can help.
Sleep at 2 Months
Most 2-month-olds sleep 14 to 17 hours over a 24-hour period, though it rarely feels like it because that sleep is broken into chunks. Many babies at this age have settled into a pattern of 2 to 3 naps during the day plus a longer stretch at night after a late feeding. Worth noting: “sleeping through the night” at this stage means only about 5 or 6 hours in a row, not the 8 to 10 hours adults think of. If your baby is doing a 5-hour stretch, that’s considered a win developmentally.
Sleep patterns vary widely between babies at this age, and there’s no expectation that a 2-month-old should have a predictable schedule. What you’re looking for is a gradual trend toward longer nighttime stretches and more alert, wakeful periods during the day.
The 2-Month Well-Baby Visit
The 2-month checkup is one of the bigger well-baby visits because it includes your baby’s first major round of vaccinations. Your pediatrician will check weight, length, and head circumference, assess the milestones listed above, and administer several vaccines. At the 2-month visit, babies typically receive their first doses of vaccines protecting against rotavirus, diphtheria, tetanus, whooping cough, a type of bacterial meningitis, pneumococcal disease, and polio. Some babies also get their second dose of the hepatitis B vaccine at this visit if they didn’t receive it at the 1-month mark.
Your baby may be fussy, sleepy, or slightly feverish for a day or two after vaccinations. This is a normal immune response. Your pediatrician will walk you through what to expect and how to keep your baby comfortable.
Signs to Bring Up With Your Pediatrician
Every baby develops at their own pace, and missing one milestone at exactly 2 months doesn’t automatically signal a problem. That said, certain patterns are worth raising at your next visit. Talk to your pediatrician if your baby doesn’t respond to loud sounds, doesn’t watch you as you move, doesn’t smile at you at all, doesn’t make any sounds other than crying, or doesn’t seem to recognize you. Also mention it if your baby’s body seems unusually stiff or unusually floppy, or if they never bring their hands to their mouth.
These aren’t diagnoses. They’re signals that your pediatrician may want to monitor development more closely or refer you to early intervention services, which are most effective the earlier they start.
