Surviving the Dreaded 4 Month Sleep Regression: A Parent’s Guide
Have you been getting blissful uninterrupted sleep only to suddenly find your 4 month old waking frequently? Are those glorious naptimes becoming a struggle? If your baby’s sleep has taken a turn for the worse, you’re not alone. The 4 month sleep regression marks a major milestone as your little one’s sleep cycles mature. While exhausting, this too shall pass. Arm yourself with knowledge and tips to tackle this tricky phase head-on. With some TLC for your baby (and yourself!) you’ll get through this sleepless period and come out the other side stronger than ever.
Why the 4 Month Sleep Regression Happens
Around the 4 month mark, your baby’s sleep cycles begin to shift from the newborn phase to a more adult-like pattern. This transition can wreak havoc on previously sound sleep. But what exactly is changing in that tiny baby brain?
Your Baby’s Sleep Cycles Are Maturing
Newborns spend about 50% of their sleep in active REM (rapid eye movement) sleep. This is why they seem to wake so frequently to feed around the clock. However, at around 4 months REM sleep decreases to about 30% and cycles between REM and quiet non-REM sleep start lengthening.
Unfortunately this maturation process means more time spent in lighter sleep stages from which it’s easier to fully wake up. Just when you thought you had this whole sleep thing mastered!
Increased Awareness Disrupts Sleep
Not only are your baby’s sleep cycles changing, but their minds are expanding too. Your 4 month old is much more aware of their surroundings. Where the world was once a sleepy blur, now new sights, sounds, sensations and stimuli constantly stream in.
This increased awareness often makes it harder for your baby to slip into deep sleep and remain asleep. A noise or sensation that was ignored at newborn phase now jolts them awake.
Ability to Self-Soothe Is Tested
A 4 month old also starts understanding they are separate from caregivers. While this is an amazing cognitive leap, it can mean losing their zen-like newborn ability to sleep anytime, anywhere.
Your baby may have an easier time self-soothing back to sleep at this point. But most aren’t quite there yet and need your help connecting sleep cycles.
FOMO Sets In
Your baby is increasingly curious, playful and eager to engage with the world around them. But there are only so many waking hours in the day. The conflict between their newfound FOMO (fear of missing out) and the absolute need for sleep is very real.
This tug-of-war between fighting sleep to play and passing out from sheer exhaustion can lead to unsettled sleep behavior.
Signs the 4 Month Sleep Regression Has Arrived
While each baby goes through this phase slightly differently, there are some common signs indicating the 4 month sleep regression is brewing:
- Frequent night wakings
- Taking short naps or fighting sleep at naptime
- Wanting to sleep in your arms or next to you rather than the crib
- Difficulty soothing themselves back to sleep
- Waking earlier than usual in the morning
- Increased fussiness, crying or crankiness from overtiredness
- Taking shorter naps or frequent catnaps
- Needing increased rocking, bouncing or intervention to fall asleep
If your well-rested baby suddenly transforms into a sleepless terror, chances are the 4 month regression has arrived. Things will improve, but how quickly depends on how you support your baby through these changes.
4 Month Regression Survival Tips
While the timing varies, most babies go through the 4 month sleep regression sometime between 3-5 months. And it often lasts 4-6 long, exhausting weeks. However, armed with the right strategies you can minimize negative sleep associations and help your baby master healthy self-soothing skills. Here are tips to try:
Maintain Consistent Sleep Routines
A consistent sleep routine is your anchor through this storm. Keep bedtime, naptime and wake times as consistent as possible. Drastic changes can worsen sleep disruptions. Stick to the same soothing rituals so your baby knows what to expect.
Watch Wake Windows
Watch your baby closely for signs of sleep readiness and put them down before they are overtired but ideally not too early either. Missing sleep windows leads to overtiredness which makes sleep even harder. Extend wake times gradually if needed.
Implement Positive Sleep Associations
Help your baby connect positive associations that signal sleep is near. This could include swaddling, white noise, lullabies, pacifiers, reading the same book, cuddling in a rocking chair, or whatever else makes them feel relaxed, comfortable and sleepy.
Don’t Nurse/Feed to Sleep
If you’ve been nursing or bottle feeding your baby to sleep, try to move eating earlier in the routine. You want them to learn to fall asleep without these associations. Break the eat-to-sleep habit before it gets too ingrained.
Make the Crib Sleep-Friendly
Ensure the crib is dark, cool and comfy so it feels like a haven. If baby startles easily, try a nested bean sleep sack to feel snuggled. Add familiar crib sheets that smell like home. You want baby relaxed in their sleep space.
Change Diapers Strategically
Try not to change diapers right before putting your baby down if it tends to rile them up. Do it earlier in the routine or after they fall asleep. Disrupting that pre-sleep calm can derail bedtime.
Allow Self-Soothing Attempts
When your baby stirs or whimpers at night, pause before jumping in. See if they can self-soothe back to sleep first. If crying escalates, comfort them just enough to calm down without fully waking up. Finding and losing that pacifier over and over can help your baby learn to self-soothe. Enable this skill.
Take Power Naps
When your sleep deprived baby finally naps, rest when they rest. Keep noise and disruptions to a minimum so they can get some much-needed deep sleep. Sleep when the baby sleeps! Even laying down quietly restores mental health.
Trade Off With Partner
Split the night into shifts so you can each get longer chunks of rest. Take turns soothing baby at night. Just be sure whoever is on duty keeps things boring, dark, and super chill. You want baby to sleep, not play.
Let In Light Gradually
Keep mornings dim with blackout curtains until your desired wake time. Light signals daytime so avoid bright light too early. Wake baby gently when it’s time to start the day so their body clock doesn’t drift earlier.
Offer Comfort Right Away
Crying escalates fast in overtired babies. Rather than waiting a few minutes, respond promptly but calmly when your baby fusses. Prevent them from working themselves into a frenzy. Meet their needs, provide soothing comfort, then try laying them back down drowsy but awake.
Address Sleep Associations
If your baby relies on rocking, nursing, their pacifier, or other sleep crutches to drift off, work on reducing dependence on these associations a bit at a time so you can put them down awake more often. Change one thing every 3-5 nights so it’s gradual.
Stick To Your Guns
Once you decide how to support your baby’s sleep, stick to it. Be consistent with your plan even if you hit some bumps in the road. Constantly changing approaches will only confuse your baby. Commit and hang in there. This too shall pass!
Manage Stress and Emotions
Lack of sleep strains mental health. Be kind to yourself and partner when tensions run high. Take breaks when needed. Limit visitors and obligations until sleep stabilizes. Protect your bandwidth – don’t spread yourself too thin.
Talk To Your Pediatrician
If sleep disruptions persist beyond 6 weeks or you have concerns about your baby’s development, check in with your child’s pediatrician. There may be additional factors at play, like reflux or allergies. Get professional insight.
Wait It Out
The 4 month sleep regression does end! It may not feel like it as you stumble through each day in a sleep-deprived haze, but your baby’s sleep will improve. Stay consistent, ride it out, lower expectations and trust this phase will pass.
