The Quick Way To Beat The Baby Sleep Regression

baby sleep regression

This may be the most dreaded sleep term for all parents. Sleep regressions imply that your previously well sleeping baby is suddenly not sleeping anymore and therefore neither are you! 


There’s good news- baby sleep regressions are temporary! But, how do you survive them!?

We will talk about every sleep regression your baby may experience and how to survive them in the meantime without going crazy from sleep deprivation.

What is a baby sleep regression?

First, let’s define what a sleep regression is. This is a period of time (usually 1-4 weeks) where your baby starts to wake more often at night or goes on an anti-nap strike.

This will cause most parents to panic, but know that it is (or should be) temporary!

Regression itself is defined as, “a return to a formal or less developed state.”

It may seem that they’ve forgotten how to sleep while they focus on something new, but again, it should only be for a short period of time.

 

It really does take you by surprise because it often comes out of nowhere!

However, as we discuss each baby sleep regression in detail, you’ll recognize signs that a regression may be coming and will be better prepared for how to handle it if/when it does.

But did you know...

There’s a theme to most baby sleep regressions and that is… development!

You can even rephrase “regression” and call it a PROgression. It often means that your little one is moving along in their development and that’s causing a brief disruption to their sleep.

This is why we don’t want to develop bad habits to survive a regression! Let's begin by understanding the sleep regression chart. 

What are the sleep regression ages ?

sleep regression ages

Here are the most common chart of sleep regression in babies (and we will discuss each one in detail):

  • 6 week sleep regression
  • 4 month sleep regression
  • 8 month sleep regression
  • 12 month sleep regression
  • 18 month sleep regression
  • 2 year sleep regression

6 week sleep regression

This sleep regression is not one parents think of usually (probably because baby is still a newborn and sleep is all over the place anyway).

However, it’s important to understand what is happening around the 6 to 8 week mark for your infant to know why a regression is possible.

Most babies go through a pretty big growth spurt around this age. That means they’re fussier and waking more often out of hunger.

However, this is also when babies are coming out of the newborn stage into the “peak fussiness stage” according to Weissbluth.

They’re noticing the world around them and that can be really overwhelming to them!

6 week sleep regression

All of that stimulation can make them overtired and overstimulated. It won’t last forever, though!

The growth spurt only lasts a few days and the peak fussiness will last a week or two. Just get through this time by feeding on demand, being mindful of awake times (around 45 minutes including feeding), and using your calming tools in the evening hours when they’re just done with the day.

You can refer to this article for more ideas on helping a newborn sleep well.

Some ideas to deal with 6 month sleep regression phase:

  • Go into a dark room with loud white noise
  • Babywearing
  • Go on a walk outside
  • Take a bath with your baby
  • The 5 S’s by Dr. Harvey Karp

It is important to remember the safe sleep rules during this time. Here’s a helpful article if you’re not sure what those rules are! 

Things will brighten up in the weeks to follow and then you’ll be ready to tackle the next sleep regression… the 4 month sleep regression!

4 month sleep regression

4 month sleep regression

If I were to poll parents, this would probably be the most dreaded of all sleep regressions!

This is generally because after the 6 week regression, sleep becomes more stable and some babies even begin sleeping through the night around 8-12 weeks of age.

Parents get spoiled with that great sleep and then as soon as it happens, it is over! So why does that happen, exactly?

The 4 month sleep regression is due to 3 major factors:

  • Their sleep patterns change and mature
  • Rolling
  • 4-3 nap transition

 

At 4 months (well, between 3-6 months), your baby’s sleep pattern will permanently change from newborn sleep cycles to adult sleep cycles.

This means that while the other sleep regressions are temporary, this one permanently changes how your child sleeps and if it is not addressed, means you will be dealing with fragmented nights and short naps for a while.

Some babies may go back to their normal day and night sleep after a few weeks and others may be dealing with poor sleep indefinitely.

This means they may have habits that need to be actively changed in order to improve their sleep habits.

 

So what does it mean when we say “permanent changes to sleep patterns?” As a newborn, your baby only had 2 stages of sleep (active/light and quiet/deep sleep).

When those sleep patterns change, they now have 5 stages of sleep and will cycle more frequently in and out of light and deep sleep.

They progressed from spending 50% of sleep in REM sleep to 25% of sleep. This allows more light sleep and more wakings.

This means they will be waking more often throughout the night, sometimes as often as every 45-90 minutes. (Sound familiar? Like maybe a baby sleep regression is happening?)

As a newborn, you were likely able to nurse or rock your baby to sleep and put her down.

This is because they go right into deep sleep. But as they get older, they begin to wake right when you put them down!

This is because stage 1 of sleep is that “drowsy” state and stage 2 is the first true stage of sleep.

Stage 3 is then where the body starts repairing and rejuvenating the immune system, muscle tissues, energy stores, and sparks growth and development.

Stage 4 and 5 is that deep, restorative sleep where memories store and the brain consolidates information.

This is very normal for their development, albeit exhausting! Your little one is right on track if you’re going through this.

That may not feel very comforting because your little one is probably waking very often at night and taking short naps. They also probably need your help to go back to sleep each time!

The good news is that this change only happens one time! Let’s just take a moment to celebrate that.

If you have been waiting and waiting for things to improve, it could be a very long time before that happens on its own with no intervention from you. This is a typical age for starting some formal sleep training.

That’s because how your baby falls asleep at night is how they’ll need to fall back asleep after their many sleep/wake cycles. If they are reliant on you to fall asleep at bedtime, they will need you to put them back to sleep each time they wake in the night.

And remember what else is happening at this age? They are learning to roll! Giving them a lot of time to practice during the day is key for gross motor development.

The reason physical milestones interrupt sleep so much is because of two things:

  1. Babies do not have the same muscle paralysis as adults do that keep us from acting out our dreams. This means if they’re dreaming about it (and they are), then they will practice this skill in their sleep and wake up in a new or different position. This is incredibly disorienting to them!
  2. Developmental skills are integrated during deep sleep. This is why they are dreaming about it! Their brain is just working extra hard during this time while they master a new skill.

Finally, a nap transition happens where they go from needing four naps a day to only three naps a day. This means their overall sleep needs are changing and naps are consolidating. Another great thing-- if we can get them taking longer naps!

In order for a nap transition to happen, awake times need to extend.Typically around 4 months, wake times are about 2 hours between each nap and bedtime. Play with the awake time to see if you can help your naps become longer!

4 month sleep regression tips

Some other methords to get you through this phase:

  • Slowly break those sleep associations and allow your baby to put themselves to sleep at bedtime
  • Try a sleep bag to build a positive sleep association (if you aren’t sure what that is, read this blog to learn all about them!)
  • Make sure baby’s sleep environment is as dark as a cave (this is because they are way more aware of their surroundings and anything they can see will distract them from sleep)
  • Use a white noise machine to minimize environmental distractions
  • Maintain a good routine around sleep
  • Consider an earlier bedtime, especially if naps are short (extra naps add extra awake time and make them more overtired, not less!)
  • Make sure you’re getting in enough daytime feedings as growth spurts often happen around regressions
  • Ask for help, take shifts, or hire a sleep consultant to help get you back on track!

Next up: The 8 month sleep regression!

8 month sleep regression

If you survived the 4 month regression, the next one to hit is the 8 month sleep regression.

The three main causes for 8 month sleep regression are:

  • Physical milestones (crawling, sitting)
  • Mental development (object permanence, separation anxiety)
  • 3-2 nap transition (if you haven’t already)

Around 8-10 months, your baby is becoming a lot more mobile. They’re rolling, sitting, crawling, scooting, pulling up, cruising, and some may even start walking! That means a lot is going on in your little one’s brain.

We already discussed why physical milestones interrupt sleep, but the key is still to let them practice, practice, practice their skills all day long.

Fun fact: This study found that out of all of the milestones, crawling was the most disruptive to sleep! “When the researchers looked at individual babies’ night wakings before, during, and after learning to crawl, they saw that the babies did indeed wake more frequently in the night when they started crawling.”

Knowing this, and knowing that all the extra activity can exhaust some babies, they can become overtired very quickly! Being mindful of awake times, sleepy cues, and utilizing early bedtimes will be your friend during this 8 month sleep regression.

Separation anxiety is a normal and necessary stage of development. The anxiety is a result of babies being able to differentiate themselves from their caregivers.

Prior to this, without object permanence, they didn’t totally realize that you were not with them. Now, they become very upset until you are reunited! Playing peekaboo is a great game for this stage.

Another helpful tip is to practice walking away while speaking to your baby, reassuring them that even though they can not see you, they can still hear you so you have not totally disappeared.

Another mental development that may contribute to the 8 month regression is language! This is when you may hear them saying “mamamama” or “dadadada” or even “no!” intentionally.

And finally, their sleep needs are changing once again. Naps are consolidating into two naps a day if they have not already. That means a late afternoon cat nap will begin to cause bedtime issues, night time wakings, or early mornings.

 

The 8 month sleep regression Tips

8 month sleep regression tips

  • Don’t assume that because they’re not sleeping well at this age that it is just because of the regression; make sure any sleep associations aren’t creating extra challenges
  • Consistency with your routines brings calm to their chaos
  • Provide extra snuggles and attention at bedtime and naptime (consider a fading approach to sleep training as opposed to methods like Ferber or extinction)
  • Check in with your sleep environment and make sure it’s conducive to sleep
  • All the practice during the day with physical milestones
  • Keep bedtime on the early side, especially if you are dropping the afternoon cat nap
  • Try to avoid old habits that you may have already broken (remember, this is a temporary phase, but the habits will still be there!)
  • Try not to stress too much (your baby can sense this)

12 Month Sleep Regression

This sleep regression primarily affects naps and most parents take that as a sign to transition to 1 nap. Unfortunately, this can be too soon for the majority of babies and sleep ends up getting worse instead of better!

It’s also not really a common regression, some kids will breeze right over it. If you’re in the trenches though, keep reading!

Here are some causes for the 12 month sleep regression:

12 month sleep regression

  • They’re more aware! They are way more interested in playing than they are sleeping. This is what leads to boycotting naps.
  • Walking (and talking); they may just be figuring out how to stand or taking a few steps independently but they’re also adding a lot of words to their vocabulary. With so many skills to practice, sleep moves lower on the priority list.
  • They just don’t need as much sleep as they used to. However, this doesn’t mean drop the nap completely!

First, you will want to encourage a lot of day time play! They are so eager to practice new skills. Try to avoid being in the car or stroller for long periods of time.

This can make them restless and store up a lot of energy which means they’re not motivated to nap and will want to practice their skills instead.

Again- don’t drop the nap yet! Only ~17% of 12 month old babies are ready for the one nap transition. The majority of kids will hang on to that nap until they’re 14/15 months old (or more).

Try to stick to your normal schedule, even if that means they only have two thirty minute naps. Play around with the awake time before naps and see if an extra fifteen minutes helps them accept the nap. Remember, sleep needs are dropping so they may not need as much sleep as we are asking from them.

At the risk of repeating myself, try to avoid sleep crutches. Sleep regressions are temporary, but habits catch on lightning fast and will be there when the regression is over.

If your little one becomes dependent on you to fall asleep, then he will probably need you to intervene when he wakes up. That could be a lot of night wakings or short naps.

We always want to provide extra comfort and reassurance without doing all of the work for them. We know that night time wake ups are frustrating and automatic reaction is to do whatever it takes to get everyone back to sleep!

But it is important to consider the long term effects of habits. This is when most families utilize their sleep training plan to get through the regression.

Definitely do what feels right for you as a parent!

Being consistent is also a huge factor in getting through a baby sleep regression quickly. It is tempting to change all the things in your routine in order to get more sleep, however that just adds more chaos to their world.

Sticking as closely to your normal routine as you can is what will get you through the sleep regression (at any age). Babies thrive on routines so they know what to expect. Try to stick to the same general sequence of events.

While sleep regressions are hard on us as parents, it is equally hard on your little one. Especially if they’re overtired! Remember to give lots of extra snuggles and comfort, but also utilize an early bedtime when needed!

18 Month Sleep Regression

Every sleep regression can be linked to some sort of mental or physical development, it seems. This one is no different!

A lot is happening around 18 months.

  • Possibly getting molars (this should not wreck sleep completely, but can exacerbate the problem)
  • Going through more separation anxiety
  • Gaining a lot of independence
  • Their language is really taking off

This one can feel like the most difficult regression because there’s a new aspect involved… discipline. The earlier baby sleep regressions didn’t have to address independence-seeking behaviors.

Your sweet little baby may now start throwing (epic) tantrums and other challenging behaviors that are new to both of you! This can lead to a lot of stress and exhaustion for you.

So add together the fact that they’re not sleeping with difficult behaviors and it will seem basically impossible because we know extra tired toddlers do not make life easy!

This may look like:

  • Nap refusals (they’ve learned they have a choice in whether they sleep or not)
  • Difficulty going to bed (again with choosing to sleep or not, but also separation anxiety)
  • Night wakings (teething, growth spurt, overtired)

If you’ve previously used sleep coaching to help your child with their sleep habits, then it is totally fine to use those same coaching methods to help you get through this regression!

Here are some tips to survive that 18 month sleep regression!

  1. Spend extra one on one time together during the bedtime routine. Don’t go wild, but add in an extra book or two for some quiet, relaxing time together.
  2. Consider introducing a lovey and snuggle it together before bed.
  3. Shift bedtime around! If your child refused their nap that day, they’ll need to go to bed about 30-60 minutes earlier than normal. If they napped extra long, consider putting them to bed 30 minutes later.
  4. Check yourself and how you react to their tantrums/demands/limit testing. The more you react (or overreact), the more you reinforce their behaviors. Try to stay calm, confident, and reassuring.
  5. Remember to set limits and enforce the boundaries. If you don’t want your child sleeping in your bed, try not to resort to it out of desperation unless you’re committed to breaking that habit in the future. You can stay firm with them sleeping in their own space. Acknowledge their feelings, support them and stay present without having to bring them to your bed.
  6. Keep offering the nap!

2 year sleep regression

2 year sleep regression

So if you’ve made it this far, you can probably assume what this regression looks like and the general reason it’s happening!

Your 2 year old may suddenly:

  • Refuse naps
  • Have difficulty falling asleep
  • Wake early in the morning
  • Wake during the night again

Here’s why it’s happening:

  • Separation anxiety peaks (again, I know…)
  • Fear of missing out (FOMO!)
  • Fears (bad dreams, etc)
  • “No” becomes their favorite word
  • Sleep needs change
  • More teething
  • Transitioning to a toddler bed too early
  • Potty training could begin
  • New sibling


As you can see, there is a lot going on for a little 2 year old! It can seem like a lot is changing at one time for them.

All the resistance to sleep will also make them really overtired. We need to be mindful of that and 1) don’t drop the nap but also 2) put them to bed early if needed.

So what’s a parent to do during this baby sleep regression?!

  1. Consistent bedtime routine but consider introducing a visual chart for added responsibility.
  2. Give choices in the routine (which pajamas do you want to wear? Which book do you want to read?)
  3. Stick to the boundaries. If you say one book, stick with one book. Or else stalling will be their new favorite thing at bedtime!
  4. Keep the nap! Now is not the time to drop it. Keep offering it even if they refuse it. The majority of toddlers will return to napping.
  5. Empathize with your toddler’s fears. A night light is okay if they’re requesting it!
  6. Keep your child in a crib as long as possible. Nothing is worse than a toddler on a sleep strike who has more freedom than they know what to do with!
  7. Create a plan for how to respond to those night wakings and stay the course.

You can see that a lot of the baby sleep regressions are similar and most are due to physical development, learning something new, and changing sleep needs.

The most important things are to be consistent, formulate a response and plan for responding to extra wake ups, and be mindful of any habits you begin during a sleep regression because they will be there when the regression is over!
