How to Get a 2 Month Old to Nap: Tips That Work

A two-month-old’s naps often feel impossible because the biological machinery that regulates sleep is still under construction. At this age, the circadian system that tells adults when to feel drowsy barely exists, and the window between “ready to sleep” and “overtired and screaming” can be startlingly narrow. The good news is that a handful of techniques grounded in infant sleep research consistently help, from how you hold your baby before a nap to how long you wait before putting them down.

Why Napping Is So Hard at Two Months

Newborns sleep in scattered bursts dictated mostly by hunger, but by about eight weeks, parents start expecting some predictability. The problem is that the brain’s internal clock still has not switched on. Melatonin, the hormone that signals nighttime drowsiness in older children and adults, does not reach meaningful circadian levels until around three to five months of age. One study tracking salivary melatonin in infants found that concentrations peaked at three to five months and then gradually declined with age, meaning a two-month-old likely has not yet developed a reliable day-night rhythm for the hormone.¹ Without that internal cue, your baby depends almost entirely on external signals and your soothing efforts to fall asleep during the day.

This is also the age when the so-called “wake window” matters most. Two-month-olds can usually handle only about 60 to 90 minutes of wakefulness before they need to sleep again. Miss that window by even 15 or 20 minutes and cortisol levels rise, making the baby wired rather than tired. You will not find a universal chart that nails the exact minute for every baby, but the signs are fairly consistent: glazed eyes, yawning, turning the head away from stimulation, and fussiness that escalates fast. Learning to read those cues is worth more than any rigid schedule at this age.

The Walk-Then-Wait Technique

If there is a single research-backed trick that parents of fussy two-month-olds should know, it is this: pick the baby up and walk. A 2022 study tested different calming methods on crying infants and found that after five minutes of walking while holding the baby, about 46 percent were already asleep and none were still crying.² That is a remarkably high success rate for a method that costs nothing and requires no equipment.

The calming effect of being carried is not just behavioral. Earlier research showed that when a mother stood up and began walking, infants stopped voluntary movements and crying almost immediately, and their heart rate slowed, a sign of genuine physiological relaxation rather than mere distraction.³ The researchers found that parasympathetic nervous system activity increased during carrying compared to simply holding the baby while sitting. In plain terms, walking triggers a deep calming reflex that sitting and rocking does not.

Here is where the second half of the technique matters. Once the baby falls asleep in your arms, your instinct is to lay them down immediately. Resist that impulse. The same 2022 study found that about a third of sleeping infants woke within 20 seconds of being placed in the crib, and the strongest predictor of whether they stayed asleep was simply how long they had been sleeping before the transfer. Infants who had been asleep for an average of about eight and a half minutes before being put down stayed asleep, while those who had slept for less than three minutes almost always woke up. The researchers suggest waiting an additional five to eight minutes after the baby appears to fall asleep before attempting the laydown.² That waiting period roughly corresponds to the length of the lightest stage of infant sleep, which has a low arousal threshold. Once the baby moves past that stage and into deeper sleep, gentle movements like lowering them into the crib are much less likely to wake them.

Swaddling Still Works, with Caveats

Swaddling is one of the oldest infant-soothing practices in the world, and the research supports it for young babies who have not yet started rolling over. A systematic review found that swaddling infants who were not already accustomed to it was associated with less arousal, more total sleep time, and more time spent in quiet (deep) sleep.⁴ The effect held for both daytime and nighttime sleep, meaning it is directly relevant for naps. The mechanism is straightforward: by dampening the startle reflex, a snug swaddle prevents the baby’s own flailing arms from jolting them awake during light sleep.

The caveat is safety. Swaddling should stop the moment a baby shows any sign of being able to roll from back to front, which for some babies happens as early as two months. A swaddled baby who rolls face-down cannot push up or turn over. At two months, most babies are not rolling yet, so the window is usually still open, but watch closely. The swaddle should be snug around the torso and arms but loose enough at the hips to allow the legs to bend and spread naturally.

White Noise and the Sleep Environment

White noise is popular for a reason. A comprehensive review of randomized controlled trials found that white noise can shorten the time it takes infants to fall asleep and improve sleep onset overall.⁵ The likely explanation is that continuous, low-frequency sound masks the kind of sudden environmental noises, a door closing, a dog barking, a sibling shrieking, that startle a lightly sleeping infant awake. For a two-month-old hovering in that fragile first stage of sleep, even a small noise reduction can be the difference between a 10-minute nap and a 45-minute one.

Volume matters. Pediatric guidelines generally suggest keeping white noise machines at a moderate level and positioning them away from the baby’s head rather than right next to the crib. The goal is a steady background hum, not a roar. Some parents find that a fan or air purifier accomplishes the same thing without the need for a dedicated machine.

Room temperature is another environmental factor that influences nap length. A study on infant sleep in cold conditions found that when clothing insulation did not match the temperature, babies’ skin cooled faster and their naps were shorter.⁶ While that study examined outdoor sleeping in a Nordic climate, the principle applies indoors too: a baby who is too warm or too cool will not stay asleep long. Most experts suggest a room temperature around 68 to 72°F (20 to 22°C) and dressing the baby in one layer more than you find comfortable.

Feeding and Nap Timing

At two months, feeding and napping are deeply intertwined, and many parents worry that their baby “can only fall asleep while eating.” That concern is understandable but often premature. At this age, feeding-to-sleep is a normal behavior, not a bad habit. The drowsiness after a feed is partly biological: breast milk contains nutrients like tryptophan that have been shown to fluctuate with a circadian rhythm, with higher levels during nighttime hours that may promote sleepiness.⁷ Other components of breast milk, including nucleotides and certain fatty acids, have also been linked to sleep modulation.

For formula-fed babies, the composition does not shift with the time of day, but the physical act of sucking and the warmth of being held during a feed still produce strong calming effects. If you are bottle-feeding and your baby routinely falls asleep mid-bottle, that is not a problem to solve at two months. It is a predictable response to the combination of sucking, warmth, and a full stomach.

A practical approach is to feed the baby upon waking, so that by the time the wake window closes, they are not starving and frantic but also not so full that spit-up becomes an issue during the nap. That said, rigid eat-play-sleep schedules are hard to enforce at eight weeks because feed intervals are still short and unpredictable. Flexibility serves both of you better than rigidity at this stage.

The Pacifier Might Not Be a Sleep Tool

Many parents reach for a pacifier as a nap aid, and pediatric guidelines do recommend pacifier use at sleep time for its potential protective effect against sudden infant death. But it may not actually change how well your baby sleeps. A study examining pacifier use, finger sucking, and infant sleep found no significant differences in sleep patterns between pacifier users and infants who did not engage in non-nutritive sucking.⁸ The researchers concluded that when deciding whether to offer a pacifier, sleep quality may not be a relevant factor. In other words, pacifiers are fine for comfort and may have safety benefits, but they are unlikely to be the thing that finally gets your two-month-old napping for longer stretches.

When Discomfort Keeps a Baby From Napping

Some two-month-olds resist naps not because of routine or environment but because they are uncomfortable. Gastro-oesophageal reflux is the most common culprit at this age. A study of parents whose infants were diagnosed with reflux found that almost all cases were identified within the first eight weeks of life, with a median diagnosis age of four weeks. Parents described symptoms including regurgitation of milk, visible discomfort, excessive crying, and difficulty gaining weight.⁹

If your baby arches their back during or after feeds, seems to be in pain when laid flat, spits up frequently and forcefully, or cries in a way that sounds different from typical fussiness, reflux is worth discussing with your pediatrician. Positioning changes can help: keeping the baby upright for 15 to 20 minutes after a feed before attempting a nap reduces the chance of acid irritating the esophagus when they lie down. For some babies, reflux makes flat-on-the-back napping genuinely painful, which means no amount of swaddling or white noise will solve the problem until the underlying discomfort is addressed.

Other common sources of nap-disrupting discomfort at two months include gas, an overly full diaper, and clothing that pinches or bunches. These sound obvious, but when you are sleep-deprived yourself, it is easy to skip the basics and assume the problem is the schedule or the routine. A quick checklist before each nap attempt, fed, burped, clean diaper, comfortable clothing, right temperature, can prevent a lot of unnecessary troubleshooting.

Safe Nap Practices

Nap safety is worth mentioning because the pressure to get a baby sleeping sometimes leads parents to compromise on sleep environment. Research consistently shows that while parents are generally aware of safe sleep guidelines, they often modify them based on what works in the moment. One mixed-methods study found that parents knew the recommendations but developed their own modifications that they perceived as making sleep safer, sometimes in ways that did not align with the guidelines.¹⁰ A separate study of mothers found that they tended to reframe sleep safety guidelines and downplay the risk of sudden infant death syndrome across all forms of sleep, including daytime naps.¹¹

The practical reality for naps is the same as for nighttime sleep: alone, on their back, on a firm flat surface, with nothing else in the crib. That means no pillows, no blankets, no stuffed animals, and no inclined sleepers or loungers. The temptation to let a baby nap in a swing, car seat, or bouncer is strong because those devices often work beautifully, but unsupervised sleep in any device that positions the baby at an incline carries a suffocation risk. If your baby falls asleep in a car seat during a drive, transferring them to a flat surface when you arrive is the safest move. A review of safe sleep interventions over 25 years found that while many programs improved knowledge about safe sleep, no study achieved complete adherence to all recommendations, which suggests this is a universal struggle, not a personal failing.¹²

What Dutch Parents Do Differently

If you are wondering whether your baby’s nap struggles are universal or partly a product of how your household runs, cross-cultural research offers an interesting lens. A study comparing infant sleep in the Netherlands and the United States using wrist-worn motion sensors found striking differences. Dutch infants averaged about 13.7 hours of total sleep per 24 hours, roughly an hour and 40 minutes more than their American counterparts, and most of that difference came from daytime sleep.¹³ Dutch babies also had shorter longest-wake episodes and spent more time in quiet sleep, the deeper, more restorative phase.

The researchers attributed part of the difference to cultural norms around infant routines. Dutch parenting culture tends to emphasize regularity, early bedtimes, and a calm, low-stimulation environment. This does not mean American parents are doing it wrong, but it does suggest that the broader household rhythm, how much stimulation a baby encounters during wake time, how consistent the sleep environment is, and how early the evening wind-down begins, shapes nap behavior in ways that go beyond any single technique. For a two-month-old, reducing stimulation in the 10 to 15 minutes before a nap attempt, dimming lights, slowing your movements, and speaking more softly, can mimic the kind of low-arousal environment that appears to support longer daytime sleep across cultures.

Combining Techniques Into a Nap Routine

No single trick works every time for every baby, and at two months you are dealing with a moving target since the brain is changing week to week. But stacking several evidence-supported techniques gives you the best odds. A practical nap routine at this age might look like this:

• Watch the clock loosely: Start winding down about 60 to 75 minutes after the baby last woke up, earlier if you see drowsy cues.
• Dim the room: Close blinds, turn off overhead lights, and reduce noise or switch on a white noise source.
• Swaddle: If your baby is not yet rolling, a snug swaddle dampens the startle reflex that disrupts light sleep.
• Walk and hold: If the baby is fussy or crying, five minutes of walking while holding them upright against your chest is one of the most reliable ways to trigger the calming response.
• Wait before the transfer: Once the baby seems asleep, continue holding them for at least five to eight more minutes before lowering them into the crib. Move slowly and keep your hands on them for a moment after they are down.

Some naps will still be 20 minutes long. That is normal at two months and does not mean you failed. Short naps are a developmental feature of immature sleep cycles, not a sign of a broken routine. Sleep cycles at this age last only about 30 to 40 minutes, and many babies have not yet learned to link one cycle to the next during the day. Over the coming weeks, as circadian melatonin production ramps up and the nervous system matures, naps typically begin to consolidate on their own. Your job right now is less about perfecting a schedule and more about creating the conditions that give sleep a chance to happen.
