Baby Waking Every 2 Hours? Causes & What to Do

Home Sleep Baby Waking Every 2 Hours? Causes & What to Do

Why is my baby waking every 2 hours?

If your baby is waking every 2 hours, the first thing I want you to know is that there is usually a reason.

Depending on your baby's age, frequent night waking may be related to:

Hunger or feeding needs
Being overtired or undertired
Feeling too hot or too cold
Physical discomfort
Their sleep environment
Developmental changes
Difficulty moving from one sleep cycle to the next
Relying on a particular type of support to get back to sleep

Your baby's age matters here too.

A newborn waking every 2 to 3 hours to feed is very different from an older baby who was previously sleeping longer stretches and has suddenly started waking every 2 hours.

So rather than jumping straight to, "How do I stop my baby waking?", I like to start with a different question:

Why is my baby waking?

That distinction is really important.

Is it normal for a baby to wake every 2 hours at night?

For newborns and young babies, regular waking overnight can be completely normal.

They have small stomachs, need frequent feeds and are still developing their sleep patterns. We should not expect a newborn to sleep through the night.

As babies get older, many become capable of longer stretches of sleep.

If your baby has been sleeping for longer periods and suddenly starts waking every 1 to 2 hours, that is when I would start looking at what might have changed.

Think about feeding, development, their daytime routine, their sleep environment and whether there is anything causing discomfort.

Why does my baby wake every 1 to 2 hours?

If your baby wakes every 1 to 2 hours throughout the night, have a look at the pattern rather than focusing on each individual wake-up.

Ask yourself:

Are they genuinely hungry each time?
Do they have a proper feed or just take a small amount before falling asleep?
Are they waking upset or simply unable to resettle?
Are they too hot or too cold?
Could they be uncomfortable?
Are they getting an age-appropriate amount of daytime sleep?
How do they usually fall asleep at bedtime?
Did they previously sleep longer stretches?
Has anything recently changed?

These clues can tell us a lot.

The goal is not simply to stop your baby waking. Babies, just like adults, naturally move through different stages of sleep overnight. What we want to understand is why your baby is fully waking and what they need in order to get back to sleep.

Why does my baby wake every sleep cycle?

Baby sleep cycles are shorter than adult sleep cycles.

Babies move through lighter and deeper stages of sleep and may stir as they transition from one sleep cycle to the next. This is why parents often tell me, "My baby sleeps for 45 minutes and then wakes up."

Some babies move into their next sleep cycle without much fuss. Others wake fully and need help getting back to sleep.

The ability to link sleep cycles develops over time, and it is something many babies become better at as they mature.

If your baby is waking at the end of every sleep cycle, the important question is what is preventing them from moving comfortably into the next one.

Why does my baby wake after 45 minutes?

If your baby regularly wakes after approximately 45 minutes, they may be reaching the end of a sleep cycle.

The question then becomes: why are they fully waking rather than moving into the next one?

This is where I look at the bigger picture.

Is your baby well fed? Are they comfortable? Is the room dark? Are they too hot or too cold? Were they appropriately tired when they went to sleep? How did they initially fall asleep?

Sometimes removing one or two simple sleep hurdles can make a significant difference.

If your baby is waking every 30-45 minutes see my blog on how to fix short naps.

Why does my baby wake as soon as I put them down?

This is an incredibly common one. Your baby falls asleep beautifully in your arms. You wait. You carefully lower them into their cot, then their eyes immediately spring open.

If your baby falls asleep while feeding, rocking or being held, being transferred into their sleep space is a significant change in their environment. If they are in a lighter stage of sleep, that change can be enough to wake them.

This does not mean you have done anything wrong by cuddling or rocking your baby to sleep.

Particularly in those early newborn weeks, there is absolutely nothing wrong with helping your baby feel safe, secure and settled. But as they get older, we can gradually help them become more comfortable falling asleep in their own sleep environment.

Check your baby's sleep environment

Before we start worrying about schedules and settling techniques, I always like to make sure the basics are right.

Have a look at your baby's sleep environment.

Check 1: Temperature

Is your baby too hot or too cold?
Babies can be sensitive to temperature changes, and being uncomfortable can make it harder for them to stay asleep.

Check 2: Light

A dark room can help create an environment that supports sleep, particularly overnight and for daytime naps as babies get older.

Check 3: Noise

Consistent white noise can help reduce environmental distractions and create a calm, predictable sleep environment.

Check 4: Comfort

If your baby is waking frequently and seems uncomfortable, consider whether something physical could be contributing.
If you are concerned that your baby is in pain, unwell, not feeding normally or otherwise seems different to themselves, speak with your GP or paediatrician.

Is your baby waking up crying every 1-2 hours with their knees up?

Colic and purple crying are describing terms for highly unsettled babies, common signs are:

Excessive crying
Knees pulling up, squirming after feeds
Fussy and irregular feeds, pulling off the breast or bottle frequently
Generally unsettled & clingy
Wakes screaming
Visibly uncomfortable & distressed
Very hard to burp no matter how diligent you are
Farting A LOT
Only wants to sleep upright e.g. pram or in the carrier and miserable when lying flat

If this sounds like your baby please read my BLOG Colic has Causes and Solutions.

What about independent settling?

Independent settling gets talked about a lot in the baby sleep world, but I think it is important to put it into context. In the early weeks, your job is not to worry about creating "bad habits". Your newborn needs feeding, comfort, closeness and sleep.

Cuddling your newborn to sleep is not going to ruin their sleep forever.

As babies get older, however, we can start helping them become more comfortable falling asleep in their sleep environment. This can make it easier for some babies to resettle when they naturally stir between sleep cycles overnight.

A predictable bedtime routine can be really helpful here. It gives your baby consistent cues that sleep is coming.

Remove the hurdles to sleep first

Before focusing on how your baby falls asleep, I want you to think about whether there is anything getting in the way of good sleep.

Some of the common sleep hurdles I look for include:

Hunger
Wind or feeding discomfort
Being overtired
Being undertired
Being too hot or too cold
Light or environmental noise
Skin irritation such as eczema
Illness or other physical discomfort

There is very little point trying to settle a hungry, uncomfortable or overtired baby. Always address the hurdle first.

Is it normal for a newborn to wake every 2 to 3 hours?

Yes. Newborns wake frequently, and that is exactly what we expect them to do.

In those early weeks, babies need regular feeds throughout the day and night. Some will wake every 2 to 3 hours, while others will have different feeding and sleeping patterns.

At this age, the focus should be on feeding, comfort, safe sleep and supporting parents to get as much rest as they reasonably can. This is not the stage to compare your baby to someone else's baby who is apparently "sleeping through".

Every baby is different.

If your newborn is extremely unsettled, difficult to wake for feeds, not feeding well, has fewer wet nappies than expected or you are concerned about their growth or health, please seek medical advice.

Is it normal for a 4-month-old to wake every 2 hours?

Around 3 to 4 months, parents can notice significant changes in their baby's sleep.

A baby who was previously sleeping beautifully may suddenly start waking every 2 to 3 hours, struggling to settle or taking shorter naps.

Parents often call this the "4-month sleep regression". I prefer to look at what is actually driving the change.

Your baby is developing rapidly at this age. Their feeding needs can change, they may be learning new physical skills and their routine or sleep environment may need to change with them.

If your 4-month-old has suddenly started waking every 2 hours, look at the whole picture rather than assuming it is a regression you simply have to endure.

What has changed? Are they hungrier? Are they comfortable? Is their daytime routine appropriate? Have they started rolling? Has their sleep environment changed?

There is often something driving the unsettled behaviour.

If this sounds like your baby - take a look at my blog on the 4 month sleep regression.

My baby used to sleep through and now wakes every 2 hours. What happened?

This can be incredibly frustrating, particularly when you thought you had finally cracked the sleep thing. A baby who previously slept longer stretches can suddenly start waking more frequently for a number of reasons:

Developmental changes,
hunger,
illness,
discomfort,
changes to their routine and
changes to their sleep environment can all play a role.

The important thing is not to assume that everything has gone backwards.

Instead, ask yourself what has changed:

When did the waking start?
What was happening around that time?
Has feeding changed?
Id milk still enough to give the the calories they need?
Do they need to start solids?
Have naps changed?
Is your baby learning a new skill?
Have they been unwell?
Is the sleep routine they are following still age appropriate?
Am I capping the morning nap?
Have you changed their room or sleeping arrangements?

That detective work can often point us towards the answer.

How do I stop my baby waking every 2 hours?

There is no single trick that will stop every baby waking every 2 hours. The solution depends on the reason your baby is waking.

I recommend starting with the fundamentals:

Make sure their feeding needs are being met.
Check for signs of discomfort.
Make sure their sleep environment supports sleep.
Look at whether they may be overtired or undertired (double check they are on an age appropriate sleep routine)
Establish a calm, predictable bedtime routine.
Support age-appropriate settling when your baby is ready.
Look at what happens when your baby wakes and what they need to return to sleep.

Remember, the aim is not to prevent your baby from ever stirring overnight. We all move between sleep cycles. What we are trying to do is remove unnecessary sleep hurdles and, when developmentally appropriate, help your baby become more comfortable returning to sleep.

How can I get my baby to sleep longer at night?

Longer stretches of sleep usually come from getting several things working together.

Feeding matters;
timing matters;
comfort matters;
sleep environment matters.
And as babies get older, the way they settle can matter too.

If your baby is waking every hour, every 2 hours or after every sleep cycle, write down what happens for a couple of nights.

What time did they wake? Did they feed? How much did they feed? How quickly did they return to sleep? Did they need rocking, feeding or cuddling each time?

Patterns are incredibly helpful. Once you can see the pattern, it becomes much easier to work out what might be driving those frequent night wakings.

Frequently asked questions about babies waking every 2 hours

FAQ 1: Why does my baby wake every hour?

ANS: Hourly waking can happen for a number of reasons, including hunger, discomfort, overtiredness, environmental factors or difficulty moving between sleep cycles. Your baby's age and what happens at each wake-up can help us understand what is going on. The 3 most common culprits I find are; snack feeding due to trapped wind; insufficient calories during the day and day sleep being at the wrong times. But every baby is different and it's important you look at their entire 24 hours to see what might be driving this frequent waking.

FAQ 2: Why won't my baby stay asleep?

ANS: If your baby falls asleep but repeatedly wakes shortly afterwards, look at the whole picture. Consider their feeding, comfort, sleep timing, environment and how they initially fell asleep. There may be one factor involved, or several.

FAQ 3: Is waking every 2 hours a sleep regression?

ANS: Frequent waking is often described as a sleep regression, particularly when a baby previously slept for longer stretches. Rather than assuming it is a stage you simply need to wait out, I prefer to look at what has changed and what might be driving the unsettled behaviour. Development, hunger, discomfort, illness, changes in routine and changes to the sleep environment can all affect sleep.

FAQ 4: Why has my baby's sleep suddenly got worse?

ANS Start by looking at what has changed around the same time. Your baby's feeding needs, development, health, daytime sleep, routine and sleep environment can all affect overnight sleep. A sudden change in sleep is a good reason to look for a cause rather than simply assuming your baby has become a "bad sleeper".

FAQ 5: When will my baby stop waking every 2 hours?

ANS: There is no single age when every baby suddenly starts sleeping longer. Babies develop at different rates, and overnight sleep is influenced by age, feeding requirements, development, comfort, routine and settling. The more useful question is usually not "When will they stop?" but "Why are they waking?"

FAQ 6: Should I feed my baby every time they wake?

That depends on your baby's age, growth, feeding requirements and why they are waking. Young babies need regular overnight feeds. An older baby waking frequently may be hungry, but hunger is not the only possible reason for waking. If you are unsure about your baby's feeding requirements, particularly for a young baby, speak with your GP, paediatrician or child health nurse for individual advice.

The bottom line on babies that wake every 1-2 hours

If your baby is waking every 2 hours, every hour or after every sleep cycle, don't start by assuming they are a "bad sleeper". Start by asking why they are waking.

For younger babies, frequent waking and overnight feeding can be completely normal. As babies get older, we can look more closely at feeding, comfort, routine, sleep environment and settling to identify what might be getting in the way of longer stretches of sleep.

Baby sleep is rarely about one magic fix. It is about understanding your baby, removing the hurdles that are getting in their way and putting the right foundations in place.

That's exactly what I teach parents inside the Dr Golly Sleep Program, with age- appropriate routines and practical strategies designed to help families better understand their baby's sleep.
