What Can 2-Month-Old Babies Do? | 8-Week Milestones

By 2 months, most babies smile in response, coo, track faces, and hold their head up briefly during tummy time.

The two-month mark brings the first real burst of social interaction. That first intentional smile, the cooing sounds, and the way those eyes lock onto yours are all part of a rapid developmental wave. The CDC’s milestone guidelines for this age focus on how your baby moves, reacts to sounds, and engages with faces — and the most important thing to know is that babies hit these markers on their own schedule.

Social And Emotional Milestones At 8 Weeks

The biggest change at two months is social. Your baby is starting to understand that people are interesting, and they’ll show it in unmistakable ways.

• Smiling responsively — your baby will grin back when you smile at them.
• Calming down when picked up or spoken to.
• Watching faces closely and tracking people as they move around the room.
• Making sounds other than crying, like coos and gurgles, especially when you talk to them.
• Turning toward familiar voices, particularly yours and your partner’s.

Your pediatrician will ask about these social interactions at the two-month well visit because they signal that your baby is connecting with the world around them.

Physical And Movement Milestones

Physically, your 2-month-old is trading the newborn curl for more deliberate movement. These are the motor skills the CDC looks for at this stage.

• Holding their head up and starting to push up when lying on their tummy.
• Moving both arms and legs with more purpose, not just jerky reflexes.
• Briefly opening their hands, beginning the transition away from tight fists.
• Looking at a toy for several seconds at a time.

You’ll also notice less head lag when you pull your baby to a sitting position — the neck muscles are strengthening fast. Tummy time is the single best way to support this development. A roundup of toys for 2-month-olds can help you pick playthings that encourage this head-lifting practice.

Senses And Communication: What They Hear, See, And Say

Two-month-olds are sensory explorers. Their vision has sharpened significantly since birth, and their hearing is now well-tuned to the human voice.

Your baby can now focus on objects about 8 to 12 inches away — the perfect distance for making eye contact while feeding. They’ll react to loud sounds by startling or pausing, and they’ll often quiet down when they hear a familiar voice. The different cries are real too: MedlinePlus notes that babies this age often develop distinct cries for hunger, tiredness, and discomfort, and they’ll sometimes respond to your voice with coos as though having a conversation.

If your baby isn’t smiling or making sounds by the 2-month mark, remember that these milestones describe what most babies do — not a strict deadline. The CDC’s guidance is clear: not reaching every item at exactly 2 months does not by itself diagnose a problem. If you’re concerned, raising it at the pediatrician’s 2-month visit is exactly the right move.

Feeding Milestones At The 2-Month Visit

Feeding at this age comes with one clear rule from the American Academy of Pediatrics: breast milk or iron-fortified formula only — no solids, no juice, no water until around 6 months.

Babies typically gain about 5 to 7 ounces per week at this age. The AAP also recommends a vitamin D supplement for breastfed babies — your pediatrician will confirm the dose at the 2-month checkup.

The single most valuable thing you can do this month is simple: talk, smile, and make eye contact constantly. Every coo you echo back and every face you make teaches your baby that communication is a two-way street — and that is the milestone that matters most at 2 months.
