By 2 months old, your baby should be smiling in response to your face, making sounds beyond crying, briefly holding their head up during tummy time, and tracking you with their eyes as you move around the room. These milestones represent what 75% or more of babies can do by this age, so they’re a useful baseline rather than a rigid checklist. Every baby develops on their own schedule, but knowing what to look for helps you support their growth and spot anything worth mentioning to your pediatrician.
Social Smiles and Emotional Connection
The social smile is one of the most exciting milestones at this age. Around eight weeks, babies begin flashing real, intentional smiles in response to something that catches their attention, usually your face or voice. These aren’t the reflexive grimaces you may have seen in the newborn stage. Your baby is now genuinely responding to you. They’ll look at your face when you’re close, seem happy when you walk up to them, and calm down when spoken to or picked up.
This is the beginning of back-and-forth social interaction. When you smile and talk to your baby, they’ll start smiling back. It’s simple, but it’s your baby’s first real conversation, and it lays the groundwork for all the social and emotional development that follows.
Sounds Beyond Crying
At 2 months, your baby should be making sounds other than crying. These early vocalizations are often called “cooing,” soft vowel-like sounds such as “aah” and “ooh.” Your baby is experimenting with their voice, learning how to control the muscles involved in speech long before actual words are possible.
You’ll also notice that your baby reacts to loud sounds, startling or turning quiet when something unexpected happens. They’re paying closer attention to voices now, especially yours, and trying to respond. Talking, singing, and narrating your day to your baby isn’t just sweet. It actively encourages these early communication skills.
Vision and Tracking
Your baby’s vision is still developing. At this age, they see most clearly at a distance of about 8 to 12 inches, roughly the distance between your face and theirs during feeding. High-contrast patterns and faces are the most interesting things in their world right now.
A 2-month-old should watch you as you move and look at a toy for several seconds when you hold it in front of them. Full, smooth tracking of a moving object typically develops closer to 3 months, but you should see your baby’s eyes beginning to follow things. If your baby doesn’t seem to look at your face at all or shows no interest in watching movement, that’s worth bringing up at your next visit.
Head Control and Movement
During tummy time, a 2-month-old can briefly hold their head up. It will be wobbly, and they won’t hold it for long, but you should see the effort. They’ll also move both arms and both legs, and you may notice their hands opening briefly rather than staying in tight fists all the time.
Pediatricians recommend 15 to 30 minutes of total tummy time per day by around 2 months. This doesn’t need to happen all at once. A few minutes after each diaper change adds up quickly. Tummy time strengthens the neck, shoulder, and arm muscles your baby needs to eventually sit up and crawl. If your baby hates it (many do), try placing a rolled-up towel under their arms to prop them up slightly, or get down on the floor face-to-face so they have something interesting to look at.
Feeding at 2 Months
Formula-fed babies at this age typically need about 2.5 ounces of formula per day for every pound of body weight. For a baby weighing around 10 to 12 pounds, that works out to roughly 25 to 30 ounces spread across the day, with a maximum of about 32 ounces in 24 hours. Breastfed babies usually take smaller, more frequent feedings than formula-fed infants, so don’t worry if nursing sessions seem short but constant.
Your baby’s appetite will vary from day to day. Some feedings will be bigger than others. What matters most is consistent weight gain and enough wet diapers, which your pediatrician tracks at well-baby checkups.
Sleep Patterns
Two-month-olds sleep a lot, typically 16 to 17 hours in a 24-hour period. That sleep is broken into stretches throughout the day and night, with no predictable schedule yet. Some babies start sleeping one longer stretch at night (maybe four to five hours), while others still wake every two to three hours. Both are normal.
You won’t have a set nap schedule at this age. Your baby will nap as needed, and the timing will shift from day to day. Following your baby’s sleepy cues, like yawning, fussiness, and eye rubbing, is more useful than watching the clock right now.
The 2-Month Checkup and Vaccines
The 2-month well-baby visit is one of the bigger appointments in the first year. Your pediatrician will check growth, assess development, and administer the first round of several routine vaccines. These typically include shots protecting against whooping cough, bacterial meningitis, polio, pneumococcal disease, and hepatitis B, plus an oral vaccine for rotavirus. It’s a lot for one visit, and your baby may be fussy or sleepy afterward. A mild fever and some irritability for a day or two are common responses.
Signs Worth Mentioning to Your Pediatrician
Because the CDC milestones represent what most babies can do by 2 months, missing several of them can be an early signal worth discussing. Pay attention if your baby:
- Doesn’t respond to loud sounds at all
- Doesn’t watch you as you move or look at your face
- Doesn’t make any sounds other than crying
- Doesn’t smile when you talk to or smile at them
- Doesn’t hold their head up at all during tummy time
- Doesn’t move both arms or both legs
- Doesn’t calm down when spoken to or picked up
Missing one milestone in isolation isn’t necessarily a concern. Babies develop unevenly, and some hit certain skills a few weeks later. But if your baby isn’t doing several of these things, or if you have a gut feeling something is off, trust that instinct and bring it up. Early identification of developmental differences leads to earlier support, and earlier support consistently leads to better outcomes.
