Getting a 2-month-old to sleep in a crib usually comes down to two things: making the crib feel familiar and putting your baby down at the right moment. Most babies need a few days to adjust to a new sleep surface, so the goal isn’t perfection on night one. It’s building comfort through repetition and setting up conditions that work with your baby’s developing sleep biology.
Why the Crib Feels Different to Your Baby
At 2 months, your baby doesn’t yet have a fully developed circadian rhythm. Newborns can’t distinguish day from night, and that internal clock is still taking shape at 8 weeks. Your baby also cycles through sleep differently than you do. Infants enter active (light) sleep first and don’t shift into deeper, quieter sleep until about 20 minutes in. That matters because if you lay your baby in the crib during that initial light-sleep phase, they’re more likely to startle awake and notice the change in environment.
A crib is also a bigger, flatter surface than a bassinet or your arms. Babies who’ve been sleeping in a snug bassinet or being held often react to the open space. This isn’t a sign that something is wrong with the crib. It just means your baby needs repeated exposure to get comfortable there.
Start With Daytime Naps
The most effective transition strategy is to begin with naps rather than jumping straight to overnight sleep. Offer one or two naps per day in the crib while keeping nighttime sleep wherever your baby is currently comfortable. This gives your baby practice in the crib during lower-stakes moments when you have more energy and patience to troubleshoot. If your baby sleeps in your room at night, daytime crib naps in the nursery are a great way to build that familiarity without changing your nighttime setup all at once.
Once your baby is napping in the crib without much fuss, you can move nighttime sleep there too. Plan for a few days of adjustment. Some babies adapt in one night, others take three or four.
Recreate What Already Works
Think about the conditions your baby currently falls asleep in and replicate them as closely as possible in the crib environment. A few specifics to match:
- Sound: A white noise machine set to a steady, low hum mimics the constant background noise your baby is used to (and blocks household sounds that trigger wake-ups during light sleep).
- Darkness: A dark room signals sleep, even during daytime naps. Blackout curtains help, especially since your baby’s circadian rhythm is still forming.
- Temperature: Keep the room between 68 and 72°F (20 to 22°C). Overheating is both a comfort issue and a safety concern.
- Routine: Use the same bedtime sequence you’ve been doing, just do it in the nursery. The familiar pattern of feeding, changing, dimming lights, and settling cues your baby that sleep is coming, regardless of where the sleep surface is.
Catch the Drowsy Window
The timing of when you place your baby in the crib matters more than almost any other variable. You’re looking for the “drowsy but awake” state, which is the brief window between alert and asleep. At this stage, the signs include a glazed-over stare, eye rubbing, fussiness, or crying. If your baby is already fully asleep in your arms, transferring to the crib often triggers a wake-up during that initial 20-minute light-sleep phase.
At 2 months, wake windows run about 1 to 2.5 hours. That means your baby can only handle being awake for roughly that long before they need to sleep again. If you push past that window, overtiredness kicks in and actually makes it harder for your baby to settle. Watch the clock loosely, but trust your baby’s cues more. When you see that glassy stare or the first signs of fussiness, start your wind-down routine.
What to Expect at Night
A realistic picture of nighttime sleep at 2 months: your baby will likely have one longer stretch of 4 to 5 hours, then wake one to three more times before morning. During that longer stretch, they may briefly stir and resettle on their own. Total sleep across day and night is around 16 hours, split between 3 to 4 daytime naps (each lasting 1 to 3 hours) and overnight sleep.
When your baby wakes at night for a feeding, keep lights dim and interaction minimal. No talking, no playing, no stimulation. This reinforces the difference between day and night and helps that circadian rhythm develop faster. During the day, do the opposite: keep your baby in bright, sunny spaces during awake time.
Swaddling and Crib Safety
Swaddling can help a 2-month-old feel more contained in the open space of a crib, but you need to watch for rolling. Once your baby shows any signs of trying to roll over, swaddling must stop immediately because rolling while swaddled increases suffocation risk. Rolling typically happens around 3 to 4 months but can start earlier, so stay alert to changes in your baby’s movement.
The crib itself should have a firm, flat mattress with a fitted sheet and nothing else. No blankets, pillows, stuffed animals, bumper pads, or sleep positioners. Place your baby on their back for every sleep.
When Your Baby Protests
Some fussing is normal and expected. Your baby is adjusting to a new surface in a bigger space, and that’s genuinely different from what they’re used to. A few minutes of mild fussing before settling is not the same as sustained, escalating crying.
If your baby is truly upset, pick them up, calm them, and try again. This isn’t a failure. You’re building a positive association with the crib, which doesn’t happen if every crib experience ends in distress. At 2 months, formal sleep training methods aren’t appropriate yet. What works at this age is gentle repetition: same routine, same environment, same timing, over and over until the crib becomes a familiar place.
Some babies take to the crib within a day or two. Others need a week of consistent practice. If you’re starting with naps and keeping nighttime flexible, you give yourself room to be patient without losing sleep over it (literally). The key variable isn’t any single trick. It’s consistency across all the small things: the darkness, the sound, the temperature, the timing, and putting your baby down before they’re fully asleep.
