You’re on all fours, crawling after your baby into the kitchen, a fresh diaper in one hand and baby’s pajamas in the other. It’s bedtime, but your baby has different plans. They scurry away, laughing, proud, with a look that seems to say, “Catch me if you can.” You’re impressed by your little one’s newfound mobility, but it has its downsides. Yawning, you glance at the clock. You’ve been chasing your baby with a diaper and pajamas for an hour now - exhausted from a day that should have ended long ago. And your routine? Out the window.
You change your approach, playfully inching closer to your little escape artist. “Got you,” you whisper as you lovingly scoop your baby up and carry them back to the bedroom; now they’re crying and fussing. Not again, you think.
Just a week ago, you could rock your baby to sleep peacefully. Now, everything’s turned upside down, and your nerves are frayed.
Your baby won’t sleep, wakes up constantly at night, is restless, fussy, and more clingy than usual? It’s likely that your baby is going through a developmental leap and learning new skills. Crawling, babbling, and discovering the world is hard work. The result: the infamous 8-month sleep regression.
What’s going on? If you’ve never heard of a sleep regression before, you’re in the right place. And if you’ve already navigated the 4-month sleep regression, you can build on what you’ve learned.
So, your baby is between three and four months old (or older) and suddenly doesn’t want to sleep anymore? No wonder you’re concerned! Don’t blame yourself; it’s not your fault. The reasons for this challenging sleep behavior are biological—and completely NORMAL. Spoiler alert: Along with learning many new cognitive and motor skills, your baby is also learning how to sleep.
How does all of this connect? What do growth and developmental spurts have to do with it? And why shouldn’t you fear the infamous 4-month sleep regression? You’ll find out next.
Below, we answer the most common questions about the 4-month sleep regression:
Simply put, regression means taking a step back. A sleep regression describes a temporary phase where your baby’s sleep patterns take a backward turn. If your baby has been sleeping fairly well up until now, you’ve probably noticed the recent sleep struggles—difficulty falling asleep, frequent night wakings, and general fussiness are all possible signs of a sleep regression.
“Not again,” you might think, especially if you’ve already gritted your teeth through the 4-month sleep regression. But don’t worry—just like before, the 8-month sleep regression doesn’t mean your baby will be a poor sleeper forever or that they’re taking a step back in their development.
Even though your baby’s sleep might seem unpredictable again, the 8-month sleep regression is usually a sign of developmental progress. Your baby is making big strides—both cognitively and physically—moving forward in their growth! Other factors like separation anxiety or changing sleep needs can also trigger a sleep regression—but more on that later. One thing is certain: the reasons behind the 8-month sleep regression are varied. But just as certain is the fact that developmental leaps and sleep regressions are normal and important phases in your baby’s life. So, “Keep Calm and Carry On.” You’re doing great!
Feeling frazzled—the 8-month sleep regression keeping you up at night? With Happy Baby, you can learn more about your baby’s sleep patterns and support them with a daily, age-appropriate sleep schedule.
Sleep regressions are a recurring topic in many families: the 4-month, 8-month, or 12-month sleep regression—you name it. Just like with other sleep regressions, there’s no set timing. The onset of a sleep regression depends on your baby’s individual development. However, there’s a general time frame when the 8-month sleep regression typically occurs, which is often between the 7th and 10th month.
Neh, Auw, Neh, Auw—your baby is crying. You’re instantly awake. Again. Groggily, you get up—for the third, fourth, fifth time tonight. Who’s even counting anymore? You lovingly cuddle your baby close while the nightly guessing game begins in your head: Is my baby hungry? Teething? Too hot or too cold? What’s going on?
Yesterday, everything was fine, but now it’s all turned upside down again. This is how many parents feel when their baby suddenly stops sleeping well: confused, exhausted, and desperate.
Understanding why your baby sleeps worse during certain phases can help you better address their needs and navigate this challenging time.
Here are some reasons that can lead to a sleep regression in babies between 7 and 10 months old:
You’re probably wondering how to recognize the 8-month sleep regression. That’s a valid question. If your baby’s sleep habits suddenly change and you notice the following signs, you’re likely in the middle of a sleep regression.
Common signs of an 8-month sleep regression include:
Worried, frustrated, and exhausted—the 8 month sleep regression is keeping you up at night again? Want to support your baby and learn more about their sleep patterns? Happy Baby creates a daily sleep schedule tailored to your child’s age and specific needs.
Sleep regressions are often linked to developmental leaps. If you notice that your baby is making cognitive, motor, and emotional strides and suddenly has trouble sleeping, it’s likely a sign of a sleep regression.
The duration is also important. A sleep regression typically starts abruptly and can last up to six weeks before your baby’s sleep normalizes again. In contrast, the process of cutting a tooth usually takes about eight days.
Not sure which it is? It’s best to consult with your pediatrician or a healthcare provider to rule out any illness.
The 8-month sleep regression typically lasts 2 to 6 weeks. Your baby’s sleep often improves once they adjust to longer wake periods and can make it to bedtime without becoming overtired. Babies older than 10 months have usually moved past this regression.
Sleep is essential for your baby. It supports growth, well-being, and healing. That’s why it’s important for both you and your baby to get enough rest. As a mom, you have a strong intuition about whether your baby is doing well or not. It’s only natural that you want to support your little one in the best way possible during this challenging phase.
Here are some helpful tips to guide you and your baby through the 8-month sleep regression:
Let’s be honest—a sleep regression can be incredibly exhausting and challenging for the entire family. That’s why it’s so important to understand what’s behind a sleep regression. By doing so, you can navigate this tough phase together.
Sleep regressions are phases in which baby's and toddler's sleep pattern can temporarily change due to growth spurts. This is a normal part of child development and often occurs around four, eight, twelve, 18, and 24 months of age. During these phases, babies and toddlers may have difficulty falling asleep and sleep poorly - at night as well as during the day. Fortunately, sleep regressions are not permanent; after a developmental leap, your child's sleep should return to normal. Parents can help their child navigate a sleep regression with a personalized sleep plan, along with consistent routines and rituals.
Are you unsure whether your baby has sleep regression and would like to understand your baby's sleep patterns? With Happy Baby, you can record your baby's sleep and create an individual sleep plan that helps you through the difficult phases.
