10 month sleep regression: Myth or real?

If your little one is going through a rough patch of sleep at 10 months, you may be grasping at straws trying to figure out what’s going on — and how long it will last. The short version is that sleep regressions (meaning sudden worsening of sleep patterns) can happen at any age. Maintaining healthy sleep habits can lessen their impact and length. 

In this article, we’ll help you identify sleep regression signs, provide you with tips for handling sleep issues at this age, and give you resources to help your child learn to sleep independently, which often leads to improved sleep.

Is there a 10 month old sleep regression?

While can happen at any age, we find that there are often patterns within particular age ranges that tend to negatively impact sleep for many children. At 10 months, it’s possible that your little one’s sleep is being impacted by developmental changes associated with the “” (that typically occurs between 7 - 10 months). 

This means your child may be experiencing a sudden worsening of sleep patterns, like fighting sleep, short naps, increased waking overnight, etc. when they had been sleeping better previously. If your little one is newly experiencing these issues, then they may be in a sleep regression. 

Why do 10 month old babies have sleep issues?

Reason #1: Sleep onset associations 

We find that independent sleepers [] tend to have an easier time at bedtime, longer naps, and fewer night wakes since they’re able to fall asleep on their own and link sleep cycles without parental help. If your kiddo is regularly helped to sleep (fed, rocked, etc. until asleep), this may result in a sleep onset association that contributes to short naps and increased overnight waking. It’s perfectly fine if you prefer to continue helping your child to sleep. However, if you’re feeling stuck and want to make a change, ! 

Reason #2: Discomfort 

If your little one is fussy at night, it could be due to some sort of discomfort, whether from or sickness. Understandably, babies tend to have a harder time sleeping when they’re in pain, congested, etc. Usually, this type of discomfort only lasts a few days to a week, and returning to your typical routine as soon as they’re feeling better can on their sleep.  

Reason #3: Separation anxiety 

At 9 - 10 months, may be contributing to your child’s sleep issues and may look like intense crying or clinginess at bedtime. Children in this age group have typically started to physically explore away from you (thanks to new skills like crawling) and this newfound freedom can be accompanied by anxiety over the realization that they’re not attached to you. You’ve been the person they’ve relied on for all of their needs and it can be jarring when they discover that you’re two separate people!

On top of this, babies at this age are developing a sense of object permanence, meaning they can now grasp that you still exist even when you’re out of sight. Crying is how little ones express their desire for you to come back.

Reason #4: Developmental milestones 

Watching your little one achieve motor milestones is so gratifying, however, these big wins can disrupt sleep []. Babies become less excited about sleep and more excited to try out these new skills at bedtime! Usually, the novelty wears off after a couple of weeks. 

My 10 month old won’t nap so is this a sleep regression?

At this age, we expect babies to have somewhere around per day, spread over two naps. Ideally, each nap is about 1 - 2 hours long.  Sleep regressions can impact naps, so if your baby is suddenly taking shorter naps or skipping naps at 10 months, this could be a sign of a sleep regression. However, wake windows tend to expand at 10 months, which can also lead to short or skipped naps, so you may consider a schedule change to see if this improves daytime sleep.  

If daytime sleep troubles aren’t new and your 10 month old is consistently having trouble falling asleep and staying asleep for naps, it could also be due to the way they’re falling asleep. When babies develop a that stems from being helped to sleep (rocking, feeding to sleep, etc.), we often see shorter naps and more frequent night wakings. Teaching your little one to is often the most important step to improving day sleep. 

How long do 10 month sleep problems last?

The length of sleep regressions typically depends on the cause and the strategies you’re using to get sleep back on track. 

When does it start?

Contrary to popular belief, there aren’t prescribed start dates for sleep regressions (save for the physiological changes that occur during the “”). Instead, there are some sleep regression signs to watch for:  

• Sudden worsening of night sleep

• Baby is fussy and has difficulty settling down for sleep 

• Short naps and baby is sleeping less during the day 

• Baby is distracted during daytime feedings 

When does it end?

Unfortunately, there’s no magic end date for sleep regressions. You might expect a short period of disrupted sleep if the regression is prompted by an illness, teething, or developmental milestone. However, if you have during this period of discomfort (like rocking or feeding to sleep), this can prolong sleep issues. In this case, you may find the period of sleep trouble lasts longer — weeks or months. To get sleep back on track, it can be helpful to reset your little one’s expectations at bedtime. 

How can I tell if it's separation anxiety or 10 month sleep problems?

at 10 months is one of many factors that can result in sleep problems. It isn’t one or the other. As we explained above, separation anxiety usually kicks in after 8 months, when your little one is newly exploring away from you thanks to their new motor skills. This leads to the realization that they’re not physically attached to you, their primary caregiver. What big, scary news for a kiddo! On top of that, they also now understand object permanence: You exist even when they can’t see you. These realizations can lead to lots of tears and clinginess at sleep times when it’s time to separate from you. 

How do I know if it's teething or 10 month sleep regression?

The discomfort and pain may be another factor that leads to poor sleep at 10 months. Your baby may be getting quite a few teeth — the central and lateral incisors can erupt around this time. Fortunately, teething pain typically only lasts about a week. A study [] found that teething symptoms tend to occur over 8 days: 4 days before a tooth emerges, the day the tooth erupts, and the 3 days after. 

Teething can be at the root (ha!) of a sleep regression at 10 months and the hope is that once the discomfort from new teeth ends, sleep will improve. To avoid prolonging sleep issues during this period, go ahead and offer extra snuggles to comfort your little one but try to stick to your normal bedtime habits as much as possible.  

4 tips to handle 10 month old sleep issues

Tip #1: Consider a “by the clock” schedule 

A good way to reduce night wakings is by making sure your little one's not overtired at bedtime. generally have a harder time falling asleep and staying asleep. Now that your baby is 10 months and may be ready for a more predictable sleep schedule, consider planning their naps and bedtime at around the same time every day, rather than strictly according to wake windows — which can lead to a lot of variabilities. Consistent sleep and wake times help regulate a baby’s circadian rhythm, making it easier for them to fall asleep and stay asleep.

However, note that a “by the clock” schedule doesn’t disregard wake windows. When scheduling their sleep times, note that most children this age need around 3 - 3.75 hours of awake time before they’re ready to snooze again. Ideally, your child’s schedule will take these age-appropriate wake windows into account.

Tip #2: Establish a consistent bedtime routine 

A can be a great way to help your child wind down and understand that sleep is going to come next. An example of a baby’s routine may look like this: 

1. Bath 

2. Diaper change and pajamas 

3. Breastfeed or bottle-feed 

4. Dim lights and sleep sack on 

5. Read a board book while snuggling 

6. Sing a lullaby 

7. Turn off lights, kiss goodnight, and lay baby down awake in a crib 

This is just one example of what a bedtime routine may look like — feel free to modify and include activities that fit your schedule and preferences. 

It’s best if the routine you choose is done in the same order every night (you could do a shorter, modified version for naptime).

Tip #3: Offer time to practice new skills

Babies are so thrilled by their own mastery of motor skills that they often want to practice these new moves when they’re . It’s common and expected, even though it’s frustrating. To avoid bedtime turning into playtime, try giving your little one plenty of time to practice new skills (standing, crawling, etc.) during awake times throughout the day. Rest assured this is just a phase it may take a few weeks before they master the skill and it no longer impacts sleep. 

Tip #4: Consider sleep training

Helping your child learn to fall asleep independently when it’s developmentally appropriate can be a big step toward improving sleep. If you’ve been helping your little one fall asleep, whether it’s rocking, feeding, or holding, this creates a that can lead to more night wakes and shorter naps. If this isn’t working for your family any longer, you might consider a

Some methods have a more gradual, gentle process and some have a approach. It’s important to that seems like a good fit for your child and your parenting style. Note that we don’t recommend sleep training if your little one is experiencing discomfort from sickness or teething. Instead, give them time to feel better before beginning a new sleep training method.
