My 6-Month-Old Wakes Every 2 Hours — Is This Normal?
If your six-month-old is still waking every few hours overnight, you might be wondering: should they be sleeping longer by now?
Maybe you've been told that by six months your baby should be sleeping through the night.
Maybe you've seen other parents posting about their baby sleeping 10 or 12 hours.
Or perhaps you've simply reached the point where you're exhausted and wondering whether something needs to change.
The good news is that frequent night waking at six months is far more common than you might think — fewer than 20% of six-month-olds are sleeping a full 12 hours a night.¹
And while "normal" doesn't mean you have to put up with being exhausted forever, it does mean that waking during the night isn't automatically a sign that something is wrong.
So, how many six-month-olds actually sleep through the night?
This is where things get interesting.
The phrase "sleeping through the night" sounds very straightforward, but it doesn't have one universal definition. Depending on the study, it can mean anything from around five or six hours of uninterrupted sleep to eight hours or more.
And a 12-hour, uninterrupted night certainly isn't the experience of every six-month-old.
In a study looking at 6-month-old infants over multiple nights, Pennestri and colleagues found substantial variation from one baby to another — and from one night to the next. In their sample of 44 babies, just 6% managed a consistent six-hour stretch.²
A much larger study of 715 babies aged 6–12 months found that 78.6% were still regularly waking at least once during the night — anywhere from 0 to 7 wake-ups a night — with night waking becoming less frequent as babies got older.³ Interestingly, having more milk or solid food during the day was associated with fewer night feeds, but not fewer night wakings.⁴
And in a large Norwegian study of 55,831 infants, Hysing and colleagues found night waking was common at six months, with the frequency of night waking generally decreasing between 6 and 18 months.⁶
So if your six-month-old wakes during the night, you're not looking at an unusual baby.
You're looking at a baby whose sleep is still developing.
Your baby's sleep isn't supposed to look like adult sleep
One of the biggest things that can help when you're trying to understand infant sleep is remembering that babies don't simply sleep like tiny adults. Infant sleep develops rapidly throughout the first year. Their sleep architecture changes, their circadian rhythms mature, and their ability to consolidate sleep gradually develops over time. There is also considerable individual variation in how this process unfolds.
Babies also move between different stages of sleep throughout the night, just as adults do. You probably have brief arousals yourself without consciously registering them. You might roll over, pull the covers up, turn your pillow over, have a sip of water or cuddle closer to your partner before drifting back to sleep. Your baby has these changes in sleep too.
The difference is that your baby is still developing the skills and abilities needed to manage many of these transitions independently. So they might call out for you. And that isn't necessarily a problem that needs fixing.
Why is my baby waking so often?
There isn't one single reason why babies wake during the night.
Night waking can be influenced by lots of different factors, including:
hunger and feeding needs
developmental milestones
their sleep environment
sleep pressure
temperament
illness or discomfort
needing comfort and connection
And importantly, waking isn't automatically caused by the way your baby falls asleep.
Feeding to sleep doesn't necessarily cause night waking
You may have heard that feeding your baby to sleep has created a "sleep association" and is therefore the reason they're waking overnight. But there's an important distinction here. Your baby can wake for all sorts of reasons.
Once they're awake, they may have a familiar or preferred way of getting back to sleep — perhaps feeding, rocking, cuddling or being held. That doesn't necessarily mean that the thing helping them back to sleep caused the waking in the first place.
If feeding to sleep is working well for your family, there's no rule saying you have to stop simply because someone has told you it's a "bad habit."
And if it isn't working for you anymore, that doesn't mean you've done anything wrong either. You can make changes when you are ready.
Will starting solids make my baby sleep longer?
This is another piece of advice parents hear frequently: "They're waking because they're hungry. Give them more food/a large bottle of formula and they'll sleep through." It sounds logical, but the research doesn't support it as a reliable solution.
In Brown and Harries' study, babies who received more milk or solid food during the day were less likely to feed overnight, but they were not less likely to wake overnight.⁴
There is no evidence at all that giving solids helps a baby sleep through the night.⁵
So while nutrition is obviously an important part of your baby's wellbeing, adding solids or increasing calories isn't a guaranteed sleep solution.
But what if I'm exhausted?
This is where I think the word normal can sometimes be unhelpful. Because telling an exhausted parent: "Don't worry, night waking is normal!" doesn't magically make them less exhausted.
Normal doesn't mean you have to be miserable.
And responsive parenting doesn't mean that nothing about your baby's sleep can change. You don't have to choose between connection and sleep. Instead of looking for a magic solution to the 2am wake-up, we can start by understanding why your particular baby is waking and what is happening when they wake.
Start by looking at the whole 24 hours
If I were supporting a family with a baby who was waking frequently overnight, I wouldn't immediately start by trying to eliminate the wakes. I'd want to understand the whole picture.
How much sleep does your baby actually need?
Every baby is an individual. If a 14-month-old is waking frequently overnight, for example, I'd want to look at their total sleep across 24 hours and ask whether we're expecting more sleep than that particular child actually needs.
More sleep isn't always better sleep. Sometimes the goal isn't to add more sleep — it's to help the sleep a child needs happen in a way that works better for the whole family.
What does their sleep pressure look like?
Sleep pressure is another important piece of the puzzle. Is your little one getting enough time awake between sleeps to build the sleep pressure they need for a longer stretch? Or could they be going into the night without enough sleep pressure? This is one reason why looking at the entire day can tell us much more than simply counting night wakes.
What do the wakes actually look like?
This is one of my favourite questions to ask parents. Because "my baby wakes four times a night" doesn't tell me very much on its own.
Are they:
briefly stirring and going straight back to sleep?
waking for a feed and settling immediately afterwards?
waking and needing some help to resettle?
fully awake and wanting to play?
distressed?
awake for 10 minutes?
awake for an hour or more?
Those are very different situations.
The number of wakes is only one piece of the puzzle.
What about responding to your baby?
If your baby wakes and calls for you, responding to them isn't something you need to be afraid will make them "too dependent" on you. This is where attachment theory gives us an important lens.
John Bowlby's attachment theory describes proximity-seeking as a normal part of the attachment system. When children are distressed or need support, they seek proximity to their attachment figure. A responsive caregiver can provide a safe haven when the child needs comfort and a secure base from which they can explore.
Attachment research has continued to explore how sensitive, responsive caregiving contributes to secure attachment and the child's developing sense that their caregiver will be available when needed. So when your baby wakes and reaches for you, you aren't creating a problem simply by responding. You're responding to a communication from your baby. And that doesn't mean you have to respond in exactly the same way forever.
From dependence grows independence
One of the things I love about responsive parenting is that it doesn't require us to choose between dependence and independence. Your baby doesn't need to prove that they can manage without you before they're ready. Instead, they can gradually develop confidence from knowing that when they need you, you are there.
As your baby grows, their needs change. Their abilities change. Their sleep changes. And the way you respond can change too. You can make gradual changes to sleep while continuing to be responsive and connected. You don't have to leave your baby to cry in order to work towards better sleep.
You don't have to choose between connection and sleep
If you're waking every two hours, it's completely understandable that you're looking for something to change. And if feeding, rocking, cuddling or holding your baby back to sleep is no longer sustainable for you, that matters too.
I remember nights like this myself — doing the maths on how many hours until morning, wondering if I was the only one whose baby hadn't read the "sleeping through by six months" memo. What I needed wasn't someone telling me it was normal. It was someone who actually understood my baby, sitting with me to work out what could realistically change.
Responsive sleep support isn't about telling you to simply accept exhaustion because night waking is biologically normal. It's about looking at the whole picture and finding changes that are appropriate for your baby, your family and your goals.
There isn't a magic solution that works for every baby at 2am. Instead, better sleep often starts with understanding:
What does this particular baby need?
How much sleep do they need across 24 hours?
What does their sleep pressure look like?
What is happening during their wakes?
Are there developmental changes happening?
Are they comfortable?
Are their sleep environment and routines supporting them?
Are there any underlying issues that could be affecting sleep that need to be addressed first?
And perhaps most importantly:
What is working for your family, and what isn't anymore?
You don't need to choose between responding to your baby and getting more sleep. You can have both. And if you're ready to make some changes, you can do that gently, gradually and responsively — without leaving your baby to cry it out.
Not sure where to start?
