What To Do When Your 9 Month Old Won’t Sleep


Tip #1: Start a consistent daily schedule for your 9 month old baby

Day and night sleep work hand-in-hand. Sleep problems like night wakings and fighting bedtime or naps are often caused by an inconsistent daily schedule.

Routines are essential for helping babies sleep well. A consistent sleep schedule sets your baby’s block clock to sleep at predictable times, making it easier for her to settle for naps and at bedtime. It’s essential that your baby naps often and enough everyday.

Your 9 month old needs 2-3 hours sleep during the day. This is the combination of all naps.

If your baby sleeps less than 2 hours during the day, over-tiredness will make her restless, hard to settle, and unable to sleep long stretches.

If your baby sleeps more than 3 hours during the day, she may not be tired enough to sleep through the night. Too much daytime sleep can also push bedtime late or make your baby wake early in the morning.

Your 9 month old’s awake times should be 2.5 – 3.5 hours.

Babies can’t handle being awake for long periods. Some babies show signs that they’re sleepy like rubbing their eyes, yawning or “zoning out.” This makes it easy for parents to know it’s time for a nap.

Other babies give their parents no sleepy signs! They can go all day without appearing to need a nap. Don’t be fooled mama! These babies need to nap just as much as other babies.

So make sure your 9 month old naps often (every 2.5 – 3.5 hours) and enough (a total of 2-3 hours.) If your baby goes to daycare, ask them to follow awake times too.

If you haven’t yet started a sleep schedule for your baby, this sample daily schedule will help you create one.

Tip #2: Create a relaxing bedtime routine

The purpose of a bedtime routine is to calm your baby in the evening, so that her body can relax and welcome sleep. Certain activities have been proven to relax babies, and when done in the right order, it sets your baby up for sleeping longer at night.

Every baby will benefit from a calming and peaceful bedtime routine each evening. Plus, research has shown that including Dad in baby’s bedtime routine decreases paternal stress and helps him bond with baby.  

It’s never too late to start a relaxing bedtime routine. It’s something that will soothe your 9 month old when she’s sick, teething, going through a regression or when traveling. So make sure to keep up with it every night.

Tip #3: Keep a consistent bedtime

Many parents think that it doesn’t matter what time their baby goes to bed. I really wish this were true! But research has shown that late or inconsistent bedtimes lead to worse sleep in children, higher aggression and attention problems.

Babies really do have a “sweet spot” for bedtime and when you get your baby to sleep at the right time he will settle easily, sleep longer stretches and sleep later in the morning. I’ve seen this works with hundreds of babies!

Your 9 month old’s bedtime should fall between 6:30-8 pm. This is the range for bedtime. But make sure your baby’s bedtime doesn’t vary by more than 20 minutes each night.

Inconsistency with your baby’s bedtime makes it harder for him to settle and fall asleep. Your baby will fight bedtime if it falls at different times each day.

My 9 month old won’t nap

There are several reasons why your 9 month old baby won’t nap or is fighting naps. The most common reasons are that awake times aren’t right, your baby doesn’t have a nap-friendly space, or your baby needs to drop a nap.


Nap Tip #1: Watch your baby’s awake times

Remember, your baby needs to nap every 2.5 – 3.5 hours. Napping this often works with your baby’s innate body clock and helps your little one not fight naps.  

If your baby is overtired in general, aim for 2.5 hour awake times. Once your baby starts sleeping better, you can extend to 3 – 3.5 hours.


Nap Tip #2: Give your baby a nap-friendly space

When possible, your baby should nap at home in his crib. This leads to the best quality sleep. If your baby goes to daycare, make sure he naps in a crib.

Start a calming pre-nap routine to help your baby wind down and fall asleep easily. Do a mini version of your bedtime routine to give your 9 month old the cue that it’s time to sleep.

Just like with night sleep, put your baby in a sleep sack, darken his bedroom and play white noise for naps. These familiar, sleep-inducing cues will help baby fall asleep easily and not wake early from a nap. Ask your daycare to play white noise and darken the room if possible too!

It’s ok if baby’s third nap (usually a cat nap) happens in the stroller or car. Also, if your baby is caught in a short napping pattern, motion can help extend naps. Let baby nap in the stroller, baby carrier or swing. Just make sure to supervise all naps outside of the crib.


Nap Tip #3: Know when to drop the third nap

Your 9 month old will be ready for 2 naps a day when she sleeps well at night and can take naps that are one hour or longer. Until then, it’s ok if your baby takes 3-4 short naps. Napping often is more important than the number of naps each day.

If your baby suddenly starts skipping naps, pushing naps later, fighting bedtime or waking early in the morning, she could be ready to transition from 3 to 2 naps.

This article explains when your baby is ready to drop the third nap, and the best way to handle this transition.

My 9 Month Old Won’t Sleep Through the Night

The reasons why your 9 month old won’t sleep all night are almost endless! It could be due to a sleep regression, separation anxiety, teething, developmental milestones or simply that he hasn’t yet learned how to.

Let’s discuss each of these below.


Reason #1: The 8-10 month sleep regression

Sleep regressions are temporary disruptions in your baby’s sleep caused by developmental milestones. When your baby is mastering a new skill (like crawling or pulling to stand) it’s normal for sleep to temporarily regress.

Most babies experience a rough patch in sleep sometime between 8-10 months. Truth be told, this regression can be one of the worst. But remember, it’s temporary and usually passes within 1-2 weeks.

This article has all the details on the 8 -10 month sleep regression, plus tips to help your baby get through it.


Reason #2: Separation anxiety

Around 9 months old your baby goes through two big developments. First, he’s able to distinguish one person from another. And second, he starts to understand the concept of object permanence. These two developments can lead to separation anxiety.

Also, in times of big change (like starting daycare or mom returning to work) separation anxiety can increase. Your baby will look to you for comfort and stability, and may not be able to sleep without your help.

Separation anxiety can make your 9 month old unsettled when you’re not present. It’s a normal phase of development and not a sign that something is wrong. The intensity varies from child to child.

The best way to handle it is to spend as much time as possible with your baby. Find moments to spend quality time together, especially before bedtime. Do a lot of cuddling, kissing, story telling, and chatting. Show him that you’re there for him.


Reason #3: Teething

Some babies sleep right through teething, without any apparent discomfort. And others seem to really suffer. If you baby appears to be in pain from teething, there are remedies you can use to reduce discomfort.

Reason #4: “My baby stands up in her crib”

There’s a lot of change and activity happening in your baby’s brain right now! Understandably, this makes it harder for her to settle down and sleep long stretches.

Most babies will go through a phase of wanting to sit, stand or crawl around the crib rather than sleep. If your baby is happily awake and practicing new skills during the night, do your best to give her space. Sure, she’ll lose some sleep over the next few days. But she’s learning to move around and get herself comfortable in the crib on his own- a vital self-soothing skill!

If your baby is “stuck” standing or sitting in the crib, and she’s upset about it, then help her lie down. If she pops right back up, try backing off for several minutes to let her practice repositioning herself. Otherwise you may get caught in a game of “jack-in-the-box” for weeks!


Reason #5: Your baby has never slept through the night

By 9 months old, most babies have the ability to sleep all night without feeding. But I’ve found that the majority of babies don’t naturally fall into sleeping through the night. They have to be taught how!

Even if your baby still needs one night feed, you can get him sleeping 6-8 hour stretches overnight. My Weaning Night Feedings Guide explains how.

The best way to set your baby up to sleep all night is to follow all the tips from this guide! 🙂 Specifically, start a consistent daily schedule, create a relaxing bedtime routine and keep a consistent bedtime.

One other essential step to sleeping through the night is getting your baby settling himself to sleep. When your baby can go into his crib awake and fall asleep on his own, he’ll be able to resettle himself each time he stirs at night.

If your baby is nursed, rocked or helped to sleep, he’ll continue to need your help falling back asleep during the night. By 5-6 months old, we know babies have the ability to learn to settle themselves to sleep. We parents just have to show them how!

This is what I help parents do everyday in my sleep training program. Although it may feel overwhelming, stressful or sometimes impossible, it’s totally possible to get your 9 month old sleeping all night.

I hope you’ve enjoyed all the tips from this 9 month old baby sleep guide. When you implement these tips for 1-2 weeks consistently your baby will start sleeping much better!
