Updated Feb 07, 2025
When your baby’s sleep patterns change, it can leave you wondering whether it’s a regression to wait out, or whether you should take action. We’re here to help! Read on for a breakdown of the most common sleep issues (and solutions) for 6 month olds.

Is there a 6 month old sleep regression?
Six months is a common age where babies may experience poor sleep due to a variety of factors. In fact, can vary and they may occur at any age. If a baby that was sleeping well suddenly starts having new sleep issues (like fighting sleep, increased waking, shorter naps, etc.) we would call this a sleep regression.
| Myth | Fact |
|---|---|
| All babies experience a sleep regression at exactly 6 months. | Not all babies go through a sleep regression at 6 months; it varies by baby. |
| Sleep regressions are always caused by teething. | Sleep regressions can be caused by various factors including developmental milestones, not just teething. |
| Sleep regressions last for months. | Most sleep regressions last only a few weeks, though this depends on a variety of factors. |
| There is nothing parents can do to help their baby during a sleep regression. | Parents can implement strategies to help their baby through a sleep regression, such as maintaining a consistent routine and creating a relaxing sleep environment. |
| Babies should sleep through the night by 6 months. | It's normal for 6 month olds to wake up during the night. |
Why do 6 month old babies have sleep issues?
There are a variety of factors that may lead to poor sleep at around 6 months, including:
Sleep onset associations
Overtiredness
Too much day sleep
Hunger
Discomfort
Mastering milestones
Separation anxiety
We'll explain more about these factors below:
(1) Sleep onset associations
Infants who are rocked, fed, or otherwise helped to sleep by their parents, tend to wake up during the night more. Since they receive help at bedtime, they’re more likely to call out for help [] when they wake between sleep cycles at night. The same goes for day sleep: parental help often leads to shorter naps.
(2) Overtiredness
When your baby stays awake too long in between sleep periods, this leads to a build-up of hormones which makes it harder for them to fall asleep and stay asleep. Aim for wake windows of 2 - 3 hours between naps and before bedtime. This will help limit overtiredness.
(3) Too much day sleep
Most 6 month olds need about 14 hours of sleep over a 24-hr period (though this can vary depending on their individual sleep needs). If a baby naps for more than 3 - 3.5 hours or takes more than 3 naps, this can interfere with getting sufficient nighttime sleep.
(4) Hunger
Many babies this age will sleep better at night with 1 - 2 nighttime feedings. Infants who regularly eat more than that during the night may continue to eat less during the day because they’re not as hungry. This can create a cycle where your baby will continue to make up the intake during the night.
Keep in mind that many babies have a growth spurt [] at this age. You might notice an increase in appetite for 2 - 3 days, which may temporarily lead to some new hunger-related wakings.
(5) Discomfort
Babies who are sick, teething, or otherwise in discomfort tend to wake more at night. If your baby wakes mid-sleep cycle during the night (meaning that they wake sooner than 40 - 50 minutes after falling asleep), this can be a sign that they’re uncomfortable or in pain
(6) Mastering milestones
When babies begin to master a new motor skill, whether that’s rolling, sitting up, or , sleep is often impacted. Your baby may get “stuck” in an uncomfortable position or simply prefer to practice their new moves at night. Either way, it can take a few weeks for your baby to adjust to their new mobility.
(7) Separation anxiety
Babies at 6 months may go through a period of separation anxiety [] that impacts sleep as at this age babies first start to recognize the difference between their primary caregivers and other adults.
Signs of 6 month sleep issues and regressions
If your infant is experiencing new sleep challenges, you may notice any number of the following which are commonly referred to as “6 month sleep regression signs”:
Increased night waking: Around 25 - 50% of babies [] continue to wake overnight at 6 months. However, if your child suddenly begins waking more frequently than usual overnight, we could consider this a sleep regression.
Trouble falling asleep: If your 6 month old is fighting sleep for naps and/or at bedtime, this may indicate a sleep regression. Note that a schedule adjustment may help.
Waking very early in the morning: It’s not uncommon for infants to wake earlier than normal during a period of poor sleep.
Short or skipped naps: Little ones may have trouble falling asleep and staying asleep during the day during a period of challenging sleep.
My 6 month old won’t nap so is this a sleep regression?
Infants can experience 6 month nap regressions too. However, if your 6 month old is fighting naps or has at this age, it may be because they need a schedule adjustment. You can view our sample .
If your schedule already looks good, we want to consider how your baby is falling asleep. Babies that fall asleep independently at nap time are more likely to link their sleep cycles without assistance, meaning they have longer naps.
How long do 6 month sleep problems last?
You may be wondering how long it’ll feel like your 6 month old is not sleeping. While sleep regressions don’t have definitive lengths, a return to your child’s typical sleep patterns depends on the contributing factors (teething, separation anxiety, etc.) and whether new sleep onset associations were created during this time, i.e. offering lots of extra assistance falling asleep.
How do I know if it's teething or 6 sleep regression?
Sometimes it's hard to tell, we know! Observe your little one during the day. Are they having the ? Check the following list for teething symptoms []:
Chewing on objects or hands
Drooling
Gum pain
Rash on the face
This may indicate it's teething. However, you may also want to check with your pediatrician about any concerns you may have.
6 tips to handle 6 month old sleep issues and regressions
Tip #1: Offer 3 naps per day
Taking too many naps or too few naps in a day can cause or exacerbate sleep issues. 3 naps are the sweet spot for babies this age. Typically we see that the first two naps are at least an hour long, while the third nap is a shorter 30 - 45 minute power nap.
Tip #2: Aim for wake windows that are 2 - 3 hours long
Rule out schedule-related sleep issues by ensuring that your baby’s wake windows are age-appropriate. Most babies this age can comfortably stay awake for about 2 hours before their first nap, and 2.5 - 3 hours before bedtime. Looking ahead, are generally 2.25 - 3.5 hours long. Overtired babies tend to have a harder time falling asleep, wake more at night, and often wake too early in the morning.
Tip #3: Focus on independent sleeping skills
By 6 months old, most babies are physiologically able to fall asleep without being rocked, held, or otherwise helped to sleep. Once a of falling asleep without parental assistance, they’ll be more likely to link sleep cycles both day and night. That means longer naps and longer stretches of nighttime sleep.
Tip #4: Ensure the sleep space is dark, cool, and quiet
To get your little one to start sleeping better, prep your baby’s bedroom with black-out curtains, lower temps, and white noise []. A really dark room can help ensure that the morning sun doesn’t set your baby’s internal clock to wake too early. It can also help lengthen naps by cutting out visual distractions.
Target a room temperature of 68 - 72F (20 - 22C), which is optimal for babies and adults. Invest in a machine to muffle household and neighborhood sounds that may interfere with your baby’s snooze.
Tip #5: Set a regular wake-up time
If you're looking to improve the quantity and quality of sleep, aim for a consistent morning rise time. This will help you find the best sleep times for your baby and can lead to more predictable sleep patterns. Not only does this help regulate your baby’s schedule, but it can also cut down on sleep issues like split nights (that’s when a baby stays awake for long periods during the night).
Ideally, your baby will wake within the same 30-minute window each morning. Yes, that means weekends too! If you’re in a 2-parent household, consider trading off so you each have a weekend day to sleep in.
Tip #6: Give your baby opportunities to practice motor skills
If your baby is mastering a milestone like sitting up [], chances are it will temporarily impact sleep a bit, no matter what you do. You can, however, help cut down on milestone-related sleep issues by giving your baby plenty of time and space to practice new motor skills during the day. Incorporating tummy time to work on rolling, or using floor time to work on independent sitting, can help your baby master the motor skill faster and make it a bit less exciting to work on their skills at sleep times.
When to talk to a doctor
Sleep challenges are a frustrating yet normal part of infant sleep development. However, you know your child best. If you have any concerns about their sleep patterns, are concerned that they aren’t getting enough sleep, or notice any red flags in general, we recommend consulting with their healthcare provider.
Takeaway
Stay informed: A sleep regression occurs when a baby that was sleeping well suddenly starts having new sleep issues.
Adjust schedules: Fine-tune your baby’s nap and bedtime routines to ensure they are getting appropriate wake windows and sleep durations.
Encourage independent sleep: Help your baby develop the ability to fall asleep on their own, which can improve overall sleep quality.
Create a sleep-friendly environment: Make sure your baby’s sleep space is conducive to restful sleep with a dark, cool, and quiet room.
Consistency is key: Maintain regular sleep and wake times, even on weekends, to support a stable sleep routine.
Practice motor skills: Give your baby plenty of opportunities to practice new skills during the day to reduce nighttime disruptions.
Be patient: Remember that sleep regressions are temporary and a normal part of your baby’s development. With the right strategies, you can help your baby navigate these changes and improve their sleep over time.
6 month sleep regression FAQ
Q: Is the 6 month sleep regression a myth?
A:
While we don’t recognize an official 6 month sleep regression, sleep regressions can occur at any age. Developmental milestones, nap transitions, sickness, and travel are all common triggers for a sudden decline in sleep health.Q: Can a sleep regression happen at 6 months?
A:
Yes, an abrupt change in sleep patterns can occur at any age, including 6 months old. Maintaining healthy sleep habits as much as possible can help ensure that your baby’s sleep doesn’t regress dramatically.Q: Do all babies have sleep issues at 6 months?
A:
No, some babies are capable of sleeping for long periods at night and take predictable naps at 6 months of age. Others continue to need help falling asleep and staying asleep.Q: Why is a 6 month old baby not sleeping?
A:
Sleep onset associations (typically caused by parents holding, rocking, or feeding their child to sleep), schedule problems, and hunger are the most common causes of night waking at this age. Many babies continue to need 1 - 2 night feedings at this age, even if they can fall asleep on their own and follow an age-appropriate schedule.Q: Can babies have nightmares at 6 months?
A:
Dreams - both good and bad - primarily occur during the REM stage of sleep. While infants spend much of their sleep time in the REM stage, there’s no conclusive evidence to support that babies dream or have nightmares [8] at this age.Q: 6 month old baby won't sleep unless held. What should I do?
A:
Help your baby learn to fall asleep in their crib by using a gradual sleep training method. While “cry it out” methods like the Ferber Method tend to have faster results, gradual methods can help limit tears by making smaller changes over a longer period of time. Start by using the methods at bedtime (or for the first nap) only, in order to make the process more manageable for your baby.If you're curious about what lies ahead with sleep regressions, glimpse into the future to see what you might experience once your baby is .
