What Is 8-Month Sleep Regression in Babies? (And How to Manage It!)

Have you been noticing sleep changes in your 8-month-old? You are not alone! This is about the time that exciting developments (laughing, babbling, mimicking your sounds, etc) can start to interfere with ZZZs. Enter: The 8-month sleep regression. Read on for tips on how to handle this common sleep hiccup.

Do 8-month-olds have sleep regressions?

When your baby is 8 to 10 months old, you may notice that a baby who was previously a great sleeper suddenly starts to wake up, once, twice…even three times a night! They cry for attention, need a cuddle, and may hate to be put back to bed. This is known as the 8-month sleep regression (or sometimes called the 9-month sleep regression), and it usually tags along with some big developmental changes or physical changes. (Learn about your baby's growth spurts.)

What to Expect From the 8-Month Sleep Regression

At 8 months old, your baby may begin having a hard time sleeping through the night, they may take longer to get back to sleep, and suddenly shun naps. Your baby may also kick up the fussiness and crying.

What triggers the 8-month sleep regression?

Sleep regressions can be triggered by something external that’s bugging your little one, like a cold, turning the clock forward and backward for daylight saving time, teething, or hunger. Developmental milestones can also be a big trigger for the 8-month sleep regression. Here are some more details about potential sleep-regression triggers:

Greater mobility. The 8-month sleep regression is often caused by your child’s budding abilities. At this age, babies are learning the joy of constant accomplishments! They’re beginning to crawl, walk, and explore…and they are full of the giddy excitement of spurting from place to place, pulling on this, grabbing and touching that, finding new things to put in their mouths. Most fun of all…they may be pulling to stand, which for your tot, is a fantastic and wild ride. For your little one, it’s like trying to master riding a 5-foot unicycle! It’s so exciting when you are up there, but so hard to keep your balance…especially with Baby’s very heavy head trying to remain upright!

Hunger. While your baby is now chowing down on lots of different foods, it’s important to remember that breastmilk and/or baby formula still makes up about 67% of your baby’s calories. Make sure your baby is not missing milk during the day, because if they are, they’ll wind up awake hungry all night long.

Teething. The 8-month sleep regression is often caused by teething. So, if your baby is chewing and drooling a ton and has red gums, you’ll begin to see new choppers poking through soon. In the meantime, you may have to endure some teething-related nighttime wakeups.

Temperament. The 8-month sleep regression can also be linked to your lovebug’s personality. Compared to tots with a laidback or cautious temperament, little ones who are very social or have a passionate temperament might may wake more at night. Social babies especially delight in their “conversations” with you that they wake up thinking, “Hey, Mom let’s play again!”…even if it’s 3am. (Find out your baby’s temperament here!)

Causes of 8-Month Sleep Regression

The 8-month sleep regression often takes parents by surprise—but there’s a lot going on in your baby’s world that can stir up sleep disruptions. Here are the most common culprits:

• Developmental Milestones: At this age, babies are mastering big physical skills like crawling, pulling to stand, and even cruising along furniture. While these exciting milestones are signs of healthy development, they can also make it harder for your baby to wind down. Many babies want to practice their new tricks—even at 2am! This burst in motor development can lead to restless sleep or resistance to naps.
  
• Separation Anxiety: Around 8 months, babies become more aware of their surroundings—and more attached to their favorite people (that’s you!). This growing sense of attachment can bring on separation anxiety, which may lead to fussing when you leave the room or increased night waking just to check that you're still nearby.
  
• Teething: The arrival of new teeth (often the top central incisors around this time) can cause gum pain and irritability, which may make it harder for your baby to fall asleep or stay asleep. If your little one is drooling more, gnawing on everything, or rubbing their ears, teething could be adding to the regression mix.
  

All of these changes are a normal part of your baby’s development, and the sleep regression typically passes with time, consistency, and a whole lot of patience.

8-Month Regression Signs and Symptoms

Not sure if your baby is in the throes of the 8-month sleep regression? Here are some common signs to watch for:

• Trouble falling asleep at bedtime
• More frequent night wakings
• Shorter naps or skipped naps altogether
• Increased fussiness or clinginess
• Resistance to naps or bedtime routines
• Sudden changes in sleep patterns after previously sleeping well
• Early morning wake-ups
• Newfound separation anxiety
  

How long does the 8-month-old sleep regression last?

The 8-month sleep regression may last a few days…or it could stretch on for a few weeks—even months—if it’s not handled correctly.

8-Month-Old Sleep Schedule: How much is enough?

Most 8-month-old babies sleep 12 to 16 hours a day. And that includes a stretch of 9 to 12 hours of ZZZs at night. Babies this age are likely still taking two naps a day to get the remainder of their sleep.

Strategies to Manage the 8-Month Sleep Regression

There are several strategies  for expertly handling the 8-month sleep regression. Here are my top tips:

• Use white noise for all nights and naps. White noise is like a soothing teddy bear…in audio form. High-quality, rumbly white noise can help distract babies from internal discomforts (like throbbing gums) and mask outside disturbances (like passing trucks and barking dogs). Just keep in mind that not all white noise is created equal! High-pitched white noise can be harsh, hissy, whiney, and just as annoying to babies as sirens and alarms. Low-pitched sounds that are consistent, droning, and hypnotic—like the sounds used in SNOObie and SNOObear—are perfect for lulling your babe to sleep.
  
• Top off feedings with extra fats. If you think your baby’s hungry tummy is the reason for wake-ups, add some extra fat during your evening feeds. Serving up a healthy fat like avocado or mixing a smidge of olive oil into your baby’s dinner are great ways to keep babies fuller longer. At the same time, make sure your baby is getting enough milk or formula throughout the day, too.
  
• Tackle teething pain. Swollen gums aren’t terribly painful, but they can throb more when your child lays down, which is annoying enough to wake a baby from light sleep. If you suspect that teething is stealing your baby’s ZZZs, dip a corner of a rough washcloth into apple juice and place it in the freezer. Once the sweetened washcloth is frozen, hand it over to your baby to gnaw on and relieve the pain. If the pain is more than a frozen washcloth can soothe, speak to your pediatrician about possibly using ibuprofen. (Learn more about easing teething pain.)
  
• Stash extra pacifiers in Baby’s crib. For babies who use pacifiers, tossing a few extras in the crib makes it easy for little ones to get the comfort they want when they need it. Sucking’s power to calm babies is quite extraordinary! Pacifiers can lower heart rate, blood pressure, and stress levels.
  
• Darken Baby’s room. Make sure your little one’s room is dark. Light streaming in from outside or under the door can easily disrupt sleep.
  
• Try a nightlight. Conversely, some children sleep better with a nightlight. You see, when babies (and toddlers) wake up, it’s more comforting to see their familiar room…not an endless abyss! The best nightlight for children is a dim nightlight that emits a warm, red-ish, or orange-ish glow, like the award-winning SNOObie nightlight. The standard white or blue light in most nightlights can disrupt your child’s sleep by inhibiting the release of melatonin, a red/orange light does not! 
  
• Change up your baby’s bedtime. If your baby fights falling asleep for 30 to 60 minutes, you may need to move their bedtime earlier or later. Try pushing your bub’s bedtime routine 15 minutes earlier every two to three nights if they have trouble waking in the morning, they easily doze in the stroller, and /or they’re extra cranky during the day you may need to move their bedtime earlier. Try moving your baby’s bedtime later if they show no signs of sleepiness at bedtime, wake in the middle of the night or very early the next day, refreshed and ready to go.
  
• Consider sleep training. If all else fails, you may have to try sleep training your baby. But don’t worry! Sleep training does not have to mean “cry it out.” Instead, try the gentler techniques I outline in my how to sleep train your baby guide.
  

When to Consult a Pediatrician

While the 8-month sleep regression is a normal part of development, there are times when it’s wise to check in with your pediatrician. Reach out if your baby’s sleep struggles are accompanied by signs of illness (like fever, coughing, or ear tugging), if they’re refusing to eat, not gaining weight as expected, or if sleep issues persist beyond a few weeks despite consistent routines. Your pediatrician can rule out medical concerns and offer guidance tailored to your baby’s unique needs.

Frequently Asked Questions About the 8-Month Sleep Regression

Is the 8-month sleep regression the same as the 9-month sleep regression?

Yes. Parents often note a sleep regression between 8 and 10 months. Sometimes it’s referred to as the 8-month sleep regression, and sometimes it’s called the 9-month sleep regression. But the symptoms and solutions are the same! 

Can introducing solid foods affect my baby's sleep during this regression?

Yes, introducing solid foods around 8 months can sometimes influence your baby’s sleep—though not always in the way you might expect. On one hand, solids may help your baby feel fuller, which might support longer sleep stretches. On the other hand, new foods can occasionally cause digestive discomfort or mild tummy troubles as your baby’s system adjusts, which can disrupt sleep. Plus, if you're offering solids too close to bedtime, it might interfere with settling down for the night. To help, try offering solids earlier in the day and keep an eye out for any signs of food sensitivities. If you’re ever unsure, your pediatrician can help guide your feeding schedule.
