The 18 month sleep regression comes out of nowhere and wreaks havoc on toddler’s sleep, leaving parents puzzled and exhausted. It is zero fun.

If your toddler has suddenly become clingy, or is fighting nap time, bedtime, having more night wakings or waking earlier in the morning- the 18 month sleep regression may be to blame. Or it could be that they’re ready to drop a nap or their molars are coming in. This guide will help you figure out what the heck is going on, and give you a specific plan to get your baby sleeping better, right away!

What is the 18 month sleep regression? 

 

A sleep regression is a temporary disruption in your baby’s sleep due to development. While this may sound like a negative thing, it’s quite the opposite!

Sleep regressions happen because your baby is going through significant developmental growth, which is wonderful to see, as a parent. 

When they’re developing, either physically or cognitively, it’s normal for their sleep to worsen temporarily while the brain adjusts to big developmental changes.

 

There are two things that make the 18 month sleep regression unique:

 

Firstly, your toddler is mastering several developmental skills at this age, rather than only one or two skills like earlier regressions. That can make this regression rougher than previous ones.

Secondly, your child is older now and sleep resistance tends to be stronger. A protesting toddler can be much louder and stubborn than a 4 month old!

Your toddler may now be saying “NO!” all the time or throwing tantrums throughout the day. This is really different than when your baby was younger and may have cried a bit more or was extra clingy. A toddler’s protests can be really loud and torturous, as you surely already know!

 

18 month old milestones

 

At 18 months old, your little one is learning all kinds of skills. Physical, cognitive, language and communication AND social skills. That’s a lot to handle!

 

  • Physical milestones: your toddler is probably walking at 18 months old, but they may also be walking up stairs (yikes!) or walking backwards. 

 

  • Cognitive milestones: 18 month olds imitate what we say as a way of learning. They point to things to get our attention and they are starting to understand (and imitate) the use of everyday objects, like talking on the phone or brushing their hair.

 

  • Language and communication milestones: Your toddler might be saying a few words at this age, which is super cute and amazing for us parents to witness. 

 

  • Social milestones: Your toddler may be showing interest in playing with others. They might hand you a toy, or instruct you to do something (like catch the ball.) You might also see them playing pretend games with a toy, like a doll or stuffed animal.

 

Look at how much our toddlers are accomplishing at this age!

The developmental changes your 18 month old is going through require their brain to work constantly, trying to process and master all of these new skills. As a result, sleep can take a big hit.

Whether it’s from their brain and body feeling “wired” when trying to fall asleep, or separation anxiety causing them to fear being alone at bedtime, it’s only natural that your 18 month old would have a difficult time with sleep.

Signs of the 18 month sleep regression

 

So, your toddler is having sleep troubles right now. But how can you be sure it’s the 18 month regression?

If your little one is around 18 months and their sleep has suddenly gotten worse, here are common signs that help point to a regression:

 

Separation anxiety

It’s very normal for little ones to have separation anxiety at this age. This manifests as increased clinginess and fussiness. Even the most independent of toddlers might suddenly freak out when their parents leave the room. Your baby might also cling onto you when new people are around.  

Some toddlers repeatedly look to their caregiver when they’re exploring, to make sure they’re still nearby. Many parents report their 18 month olds suddenly crying when placed in the crib at bedtime or for naps. Anytime they might be separated from you can cause them distress. 

Although it can be stressful and worry, try to remember that it’s normal. (More details coming in a minute!)

 

Practicing new skills

When our little ones are working through developmental milestones, their brains are constantly working to master it.

If you see your baby learning any of the skills mentioned in the previous section AND their sleep has suddenly gotten worse, this could be a sign of the 18 month regression. 

 

Sudden changes in sleep habits or routines with no other obvious explanation

Sudden and out of the blue changes in your baby’s sleep habits could definitely point to the 18 month sleep regression as the cause. This goes for sleep trained babies and babies still needing their parent’s help for sleep.

If your toddler hasn’t been sick recently, you didn’t go on any trips, or no other obvious disruptions to your toddler’s sleep can be figured out – chances are it’s a regression. 

 

Signs unrelated to this regression

We can’t blame the 18 month regression for everything, though!

Two other factors to be considered at this age (which can interrupt good sleep habits) are the 2-1 nap transition (when your toddler is ready to drop the second nap) and eruption of your baby’s first molars (which happens between 13-19 months.) See my teething pain remedies video here.

So, if your 18 month old is still taking two naps (and especially if they’re fighting naps) OR chewing on everything in sight, consider these two other sleep disruptors. 

 

Can this regression happen early (or late?)

 

Regressions are a by-product of your toddler’s budding development. And although most children develop in a similar timeframe, each child is different.

If your toddler is experiencing many of the signs of the 18 month sleep regression and is 17-19 months old, they could be going through this regression. Also, if your child was born premature, consider their adjusted age.

 

How long does this regression last?

 

I typically give regressions two weeks to “run their course”. Then it’s ok to begin sleep training your 18 month old.

At this point, many of your toddler’s sleep patterns will be turning into habit so it’s a great time to actively help your child start sleeping well. 

My sleep training program 21 Days to Peace and Quiet is carefully planned to fit your individual child and family. Your baby’s personality, age, and your parenting style are all taken into consideration in order to find the best method.

There’s also the option of getting personal support from me, my Support Team, and other parents who are on the same journey!

Does separation anxiety cause the 18 month sleep regression?

 

A lot of parents wonder if separation anxiety causes the 18 month sleep regression. Or vice versa. The truth is, they’re interrelated and feed off of each other.

Separation anxiety is when your baby or toddler is suddenly more upset being separated from you. They may be clingier and fussier in general, or when they’re in a new place or with new people. Many (formerly independent) little ones start crying, screaming or throwing a tantrum.

Although it can feel nerve-wracking as a parent, it’s important to remember that separation anxiety is a normal part of development. As your child goes through big changes (both physical and cognitive) separation anxiety acts as a defence, or survival instinct.

Our children become more vulnerable when they’re growing and learning new skills, so they tend to cling on to their loved ones in order to feel safe during these times of change. They cry when you leave because they want to be close to you, and they also reject unfamiliar faces and places as a way to protect themselves.

Also, preparing for sleep marks a clear time when your toddler will be away from you. That’s why going into their bedroom or putting on pajamas can make them cling on to you or start wailing.

Similarly, waking up early from a nap or throughout the night presents an opportunity to see you! (That’s an optimistic way to interpret night wakings!) 

Presenting an even bigger challenge, at this age toddlers are more aware of what’s happening around them.

They’re now old enough to understand that you’re about to leave when you put on your shoes or jacket. And depending on their personality, a bright shiny toy might not be enough to distract them from the stress of separation.

 

How to ease separation anxiety in your 18 month old

 

Your toddler is growing more clever by the day. Their new cognitive, social and emotional skills can make them very aware when you’re getting ready to leave the house or that they won’t see you for a while when they’re going to sleep. 

While this is tough for us parents to endure and can feel really heartbreaking, the best way to help our babies feel better (and sleep better) is to focus on what we can do to help them.

They need their sleep, and so do you! “Giving in” to separation anxiety can end up making matters worse.

Studies have actually shown that when separation anxiety is experienced not only by the baby, but by the mother as well, this creates more stress on both and leads to more night wakings.

That’s why it’s important to find ways to ease separation anxiety, for the sake of the whole family. Here are my top tips. 

 

Tip #1: Teach them that you always come back.

The great thing about the 18 month sleep regression is that you can use your toddler’s new skills to your advantage!

At this age, you can start introducing the phrase “coming back.” Whenever you leave, even if it’s just to go to the kitchen to get a glass of water, say “I’m coming back!” When you return, remind them by saying “See? I came back, and I will always come back!” This way, when you actually have to leave, they can be reminded that you do always come back to them.

The more you practice this phrase throughout the day, the better. You can even do it with toys or while playing peek-a-boo. 

 

Tip #2: Keep goodbyes upbeat.

Whenever you or another caregiver have to leave, keep it upbeat and happy. If you reflect your toddler’s nervous energy, this could prolong their stress.

The best thing to do is give a quick kiss, say the phrase you’ve been practicing and get moving! And when you return home, remind them that you “always come back” with a big hug. 

 

Tip #3: Spend extra time together.

One-on-one time with your little one helps ease the stress of separation anxiety. When possible, leave your phone in another room and have lots of eye contact, smiles and cuddles with your toddler.

Half an hour each day can be enough to “fill their tank” and help them feel comforted and relaxed. Definitely plan for at least 10 minutes of one-on-one time before sleep to help your toddler accept going into the crib. 

 

Tip #4: Introduce a lovey.

Loveys are a safe and effective way to ease separation anxiety in toddlers. Having a familiar object, or buddy, to cuddle helps many little ones sleep well.

See which stuffed animal or doll your toddler gravitates to, and include it in your bedtime routine. Give it to them to cuddle in the crib at bedtime and for naps. 

 

Tip #5: Stick to your regular routine.

Toddlers thrive on structure and routine. (They just don’t realize it, LOL.)  At 18 months, many toddlers protest or throw a few tantrums everyday.

While it may seem that the best thing to do is give up and throw in the towel, that tends to prolong the issue.

Sticking to your typical routine and schedule actually helps your toddler both short-term and long-term.

This time of development is confusing, tiring and overwhelming for them, but having a clear and familiar daily routine helps them relax. Knowing what they can expect (even if it’s what they don’t like- like going to sleep) helps lessen their big and overwhelming feelings. 

Just like with goodbyes, keep your routines simple and happy. Focus less on a “strict schedule” and more on a clear and fun routine!

 

An extra tip

Hanging a simple daily routine on the wall provides a lot of relief to parents and toddlers. You can make your own by drawing or printing a few pictures, or find one on Etsy.

For example, hang your bedtime routine in your toddler’s room. Include photos of bath time, pajamas, books, songs, and the crib.

Providing this visual version of your sleep routine helps your toddler understand what will happen and gives you “support” when the sleep routine ends.

Keep a clear and definitive end to your bedtime routine, to minimize their insistence on more songs or books. 

 

Nap tips

 

The 18 month regression can affect several aspects of your toddler’s sleep, including naps. It’s common to see little ones fighting naps, skipping naps or taking short naps. All in a day’s work for a toddler, right?

 

My top tips for dealing with your 18 month old’s naps:

 

Adjust your sleep schedule.

If your toddler is taking longer to fall asleep, plan for that ahead of time.

Put them down earlier for a nap, to make sure that after the “fuss” your toddler still has the opportunity to take a long nap.

 

Stay on track.

Try to avoid going back too many steps from where you are right now. For example, if your 18 month old was sleeping independently, avoid pulling them into your bed and co-sleeping for naps. (More work to undo later.)

You may need to give extra comfort or linger in their bedroom to help them fall asleep, but aim to keep them sleeping in their crib.

If your 18 month old still takes two naps a day, you can consider transitioning to one nap with my guide here. And if your toddler is completely refusing to nap, this guide will help

If your toddler was napping well before this regression, keep the same sleep schedule that previously worked. Once the regression passes, your little one should bounce back into their good napping groove.

If your toddler has never really napped well, my nap training program will show you how to get them taking long, restful naps everyday in the crib on their own.

 

Should I start sleep training during the 18 month sleep regression?

 

Sleep training during a sleep regression is like throwing gasoline on a fire. Your baby is going through a surge of development, which makes it hard for their brain and body to “switch off” and relax so they can sleep long stretches. 

The best approach when your little one is obviously struggling is to keep them as well-rested as possible. Aim for 2-3 hours of napping everyday and 10-12 hours of nighttime sleep.

You may even need to linger in your toddler’s bedroom to help them fall asleep or do more hands-on comforting like holding, rocking or feeding. 

After two weeks of disrupted sleep, you can begin sleep training your 18 month old. At this point, it’s safe to assume that any lingering sleep issues are now becoming a habit, so the best way forward is to teach your toddler to sleep through the night on their own.

My sleep training program shows you exactly how to do this!

 

To sum up…

There is a lot going on for our toddlers at this age. At 18 months old, your baby is mastering physical, cognitive, social AND emotional milestones. It’s only normal that there would be a sleep regression at this age as well as separation anxiety. 

However, following the tips in this article will definitely help you ride out the storm.

Sleep training is a really effective way of setting up healthy sleep patterns for your little one that can help them (and you) get restful sleep for years, which is something you’ll thank yourself for doing, over and over! 

Good luck!

    Hi, my daughter has started waking at 5/5.30am every morning. I leave her and try to try and get her to go back to sleep. She is 19months and has one nap in the afternoon 1.30-3.30pm. As she is waking so early by 9am she is very grumpy and tired!

      Hello, I would try to move up your LO’s naps. Toddlers at this age can handle around 5 hours of awake time in the morning. So try a schedule like this:

      6am-wakeup
      11:00-1:00pm-nap
      6:30pm-bedtime

      Give it a solid 1-2 weeks to see how your LO adjusts and follow the clock 🙂

    I have twins. We took their pacifiers away a little over two weeks ago. Also tried going to the one nap a day at that time. Baby 1 is crying every time we put her down fpr naps amd at night time. I’m not sure if it’s 18 month sleep regression, not having the pacifier or teething. Should we go back to the two nap a day for now?

      Hello Julie! It sounds like the 18 month sleep regression. I would just continue with your 1 nap, but move bedtime earlier if they don’t nap well! Alyssa, BSMS Support Team

    If 18 1/2 month old is only fighting bedtime not nap would you put in crib a little earlier like you said for nap?
    Do you still suggest waiting five minutes and going back in and padding and then going out again?

      Hello!

      I would leave nap time the same and just focus on putting him down a little earlier for bedtime. If he is just rolling around and not sleeping, I would give him space to settle. I would only go in to his room if he is crying continuously!
