2-Month-Old Milestones: Development, Growth, Speech, and Sleep

The smile is the moment everyone waits for. Somewhere around two months, your baby looks right at your face, and instead of the reflex twitch from the newborn weeks, you get a real smile back. It's the first time it feels like a two-way exchange.

Two months is also the first big checkup where the pediatrician runs through a formal list of skills. The floppy, sleepy newborn is turning into a baby who tracks you across the room, holds their head up during tummy time, and answers your voice with sounds that aren't crying. Here's what most 2-month-olds are doing, grouped the way your pediatrician thinks about it, with the numbers and the sources behind them.

What should a 2-month-old be doing?

Most 2-month-olds are smiling at you on purpose, calming when you pick them up, following you with their eyes, holding their head up in tummy time, and making cooing sounds.¹ The CDC updated its milestone checklists in 2022 so each listed skill is something about 75% of babies can do by that age, not the average.² If your baby is doing most of these, they're on track, and a wide spread in timing is still perfectly normal.

Pediatricians watch a few rough tracks maturing at the same time. Here's each one.

Movement and physical development

Head up in tummy time. Laid on their stomach, a 2-month-old can lift their head and hold it up for a bit.¹ It's shaky and it won't last long, but that neck and upper-back strength is the foundation for everything that comes next.

Moving both arms and both legs. Your baby kicks and waves with both sides of the body.¹ The jerky, startle-driven movements of the newborn weeks are smoothing out into something that looks more intentional.

Tracking you across the room. A 2-month-old watches you as you move and follows a face or a toy with their eyes.¹ That visual tracking is a real cognitive step, not just looking around.

Two months is early for rolling, so swaddling for sleep is still fine right now. Keep it snug around the chest and loose at the hips, always on the back, and plan to stop the moment your baby shows any sign of rolling in the coming months.³

Hands and fine motor skills

Hands starting to open. Newborn hands stay curled in tight fists most of the time. By two months your baby opens their hands briefly instead of holding that permanent grip.¹ Reaching and grabbing on purpose are still a couple of months away.

Hands to the mouth. You'll see your baby bring a fist toward their mouth. It's soothing for them and it's early hand-eye coordination in progress.

Speech and language

Sounds that aren't crying. The big one for this age: your baby starts making little cooing and gurgling sounds, the "ooo" and "aah" noises that are the very first raw material of speech.¹ Crying is no longer the only tool in the kit.

Reacting to loud sounds. A 2-month-old startles, stills, or turns toward a loud noise.¹ If a slammed door or the dog barking gets a reaction, hearing is doing its job.

Answering your voice. Talk to your baby and pause. Many 2-month-olds will "reply" with a coo or a wiggle. Narrating what you're doing, out loud, all day, is the single most useful thing you can do for language right now.

Social and emotional

The social smile. This is the headline. Your baby now smiles when you talk to them or smile at them, and it's aimed at you.¹ It usually shows up between six and eight weeks, so if it hasn't fully arrived at exactly eight weeks, give it a little time.

Looking at your face. A 2-month-old locks onto faces, yours most of all, and studies them.¹ Faces are the most interesting thing in their world.

Calming to you. Your baby settles when you speak to them or pick them up.¹ They're learning that you are the source of comfort, which is exactly the attachment you want forming now.

Happy to see you. Many babies this age light up when a familiar person walks over.¹ That recognition is a sign the social wiring is coming online.

How much sleep does a 2-month-old need?

About 15 hours in 24, split roughly 8.5 at night and 6.5 across four or so naps.⁴ Wake windows are short, around 1 hour 25 minutes to 2 hours, and a "schedule" is still more aspiration than reality at this age.

The good news is that the nighttime stretch is starting to lengthen. Some 2-month-olds produce one 3 to 4 hour block in the first half of the night as the circadian rhythm begins to sort day from night. We break the whole day down, with a sample schedule and wake windows, in our 2-month-old sleep schedule post, and the numbers for every age live in our wake windows chart and sleep needs guide.

Feeding a 2-month-old

Milk (breast or formula) is your baby's only nutrition at two months. Solids are months away, typically starting around six months once a baby shows the readiness signs.⁵ There's nothing to add to the diet right now.

Most 2-month-olds eat about 7 to 9 times a day, on demand, with feeds spacing out to roughly every 2.5 to 3.5 hours as the newborn constant-feeding phase eases off. Night feeds are still expected, usually 1 to 3 per night. If your baby is having plenty of wet diapers and gaining weight along their curve, they're getting enough. Our feeding guide has amounts and frequencies broken out by age.

Growth at 2 months

Babies grow fast in the first months. This month most add somewhere around 1.5 to 2 pounds and grow roughly 1 to 1.5 inches, with the head circumference climbing too.⁶ A little more or less is normal.

Your pediatrician plots weight, length, and head circumference against the WHO growth standards at the 2-month well visit.⁷ The curve matters more than any single number. A baby tracking steadily along the 20th percentile is growing exactly as they should, same as one on the 80th. You can follow the same percentile bands at home with our growth chart.

2-month milestone checklist

Development is a range, not a schedule, and no baby hits every item in the same week. Most 2-month-olds can:

• Hold their head up during tummy time
• Move both arms and both legs
• Open their hands briefly instead of staying fisted
• Make cooing sounds, not just cry
• React to a loud sound
• Watch you as you move across the room
• Look at a toy for several seconds
• Look at your face and calm when you pick them up
• Smile at you on purpose

2-month red flags: when to call the doctor

Every baby moves at their own pace, but a few signs at two months are worth raising with your pediatrician. Check in if your baby¹:

• Doesn't respond to loud sounds
• Doesn't watch things as they move
• Doesn't smile at people by around two months
• Can't hold their head up at all during tummy time
• Doesn't bring their hands to their mouth
• Seems unusually stiff or unusually floppy

None of these on its own means something is wrong, and premature babies often reach these a few weeks later based on their adjusted age. You know your baby better than any list does. If something feels off, the "act early" move is to ask sooner rather than wait and see.²

How to support development at 2 months

Talk and pause. Narrate your day out loud (diaper changes, walks, what's for your lunch) and leave gaps for your baby to "answer" with a coo. Those turn-taking moments are how conversation starts.

Get face to face. Hold your baby about 8 to 12 inches from your face and let them study you. Making expressions and slow, exaggerated mouth movements gives them something to watch and, eventually, copy.

Protect tummy time. A few minutes several times a day, always supervised and awake, builds the neck and shoulder strength behind head control. If your baby hates it, get down on the floor at their eye level, or start with tummy time on your chest.

nappi tracks feeds, sleep, and milestones in one place, so the 2-month well visit becomes a matter of glancing at what actually happened instead of reconstructing it from memory.

Frequently Asked Questions

My 2-month-old isn't smiling yet. Should I worry?

Probably not. The social smile usually appears between six and eight weeks, so at exactly two months some babies are just getting there.¹ Keep making eye contact and talking to them. If there's no social smile at all by the end of the third month, mention it at your next visit.

Is it normal for a 2-month-old to still eat every 3 hours at night?

Yes. At this age 1 to 3 night feeds are typical, and many babies still wake every few hours to eat.⁵ Longer stretches come as the circadian rhythm matures over the next couple of months. There's no need to night wean now.

How long should a 2-month-old stay awake?

Around 1 hour 25 minutes to 2 hours between sleeps, shorter than you might expect. Overtiredness comes on fast at this age, so watch for yawning and fussiness and put your baby down before the meltdown. The full breakdown is in our 2-month-old sleep schedule post.

When will my baby hold their head up steadily?

At two months, head control is arriving but still wobbly. Your baby can lift and briefly hold their head during tummy time now.¹ Steady, upright head control without support usually settles in closer to four months.
