Why Newborns Fight Sleep [And How to Help Them Settle]

Newborns can sleep up to 20 hours a day, so why does it sometimes feel like they NEVER want to sleep!?

Many parents find themselves pacing, rocking, feeding, and trying everything they can think of, only to have their newborn resist sleep completely. It can feel confusing, especially when your baby is clearly tired but just will not fall asleep.

We are Newborn Care Specialists, Postpartum Doulas, Sleep Consultants and Nurses that work with hundreds of new families in their homes every year! We find that the most common reason that newborns fight sleep is not that the baby isn’t tired enough. It is typically because they are overtired.

Why Newborns Fight Sleep

Overtiredness is the biggest reason newborns fight falling asleep

When a newborn stays awake too long, their body begins to release stress hormones. If a baby stays awake past their natural wake window, those hormones can linger in the body for hours, sometimes even into the next day.

In many ways, it’s like giving your baby a dose of hormonal espresso. Instead of becoming sleepy, they become more alert, more sensitive, and much harder to settle.

This is why a baby who “should be exhausted” can suddenly:

• cry more
• resist being put down
• seem wide awake
• fight sleep harder

This is completely normal! They aren’t giving you a hard time. They want to be sleeping too!

What overtiredness looks like

Many parents expect tired babies to look calm and sleepy. In reality, an overtired baby often looks the opposite.

Signs of overtiredness can include:

• fussiness or sudden crying
• arching or stiffening
• rubbing eyes or face
• turning their head away
• bursts of energy
• extremely wide and alert eyes

Often, when we arrive for our first overnight or daytime shift, parents tell their Newborn Care Specialist that their newborn fights sleep.

In many cases, we can quickly visually see that the baby is overtired, often just from the look in their eyes. It’s a distinct, wide-eyed, slightly glossy look that signals a baby who has pushed past their natural sleep window.

It’s very common for parents to think their baby is especially alert or simply needs less sleep than other babies. In reality, that is rarely the case.

Why It Feels Like Nothing Works

When a baby is overtired, the usual soothing methods can feel less effective. Your baby might not get settled after you feed them. You feel like you’ve been rocking them forever. You might finally get them to sleep just for them to wake back up 5-20 minutes later.

When nothing is working, it’s because their little bodies are working against the sleep that they need to break the cycle.

What Actually Helps Your Baby Fall Asleep

The goal is not to push your baby to stay awake longer.

The goal is to catch sleep before overtiredness sets in and support them in settling. If your baby is overtired, they are in a fight-or-flight state, and this is not the time to work on sleep conditioning.

If your baby is overtired, you might need to spend a full day going all in on getting them to sleep by whatever means necessary. Here are some tips and tricks that have been successful when we’ve worked with families in the past.

Emergency tips for getting your newborn to sleep when they are in a stressed state:

• Very dark room
• Very loud white noise
• Tight swaddle
• Vigorous movement [swaying or bouncing]
• Small feeding [even if you’re following Eat. Play. Sleep routine]
• Time and patience

If your body gives out before your baby does, it’s okay to place them in their crib [in the dark with sound] and step out for 5 minutes. Get some water, do some stretches and know your baby is okay [even if they’re crying]. Then tag a partner or go back in and repeat. Bringing them into the light will reset all of the hard work you’ve put in.

After they are caught up from the sleep deficit, you can begin to work on how to prevent overtiredness in the future, and how to get your baby to be the best little sleeper possible.

1. Focus on wake windows

Newborns can only stay awake for short periods. Most need to sleep every 30 to 90 minutes, depending on their age and the time of day.

If a baby is staying awake longer than that, overtiredness often begins to build. It can be a very short wake window that parents can easily miss. We usually recommend setting an alarm for when your baby wakes up so it alerts you that it’s getting to be naptime. [Example: Baby wakes at 1pm, set an alarm for 1:45pm to start looking for tired cues.]

• One month old sleep schedule
• Two month old sleep schedule
• Three month old sleep schedule

2. Watch your baby, not the clock

Yes, wake windows are important. But if you are just getting to understand your baby’s rhythms, you may not fully understand your baby’s wake windows [yet]. If your baby took a short last nap, or if they are over- or under-stimulated, that window can shift. It can feel confusing at first to know when you’ve hit the “sweet spot” for sleep.

We do want parents watching the clock for the maximum wake window that is age-appropriate, but sleepy cues are just as important when predicting baby’s next nap.

Look for early sleepy cues:

• slower movements
• softer gaze
• mild fussiness
• red eyebrows
• yawning

Trying to settle your baby at this stage is much easier than waiting until they are overtired. Ideally, you want to begin a nap or bedtime as soon as you see these cues.

It can take 10 to 20 minutes for a baby to actually fall asleep. If that window is missed, you may find yourself with a baby whose body is now working against sleep, with rising cortisol making it harder for them to settle.

3. Create a rhythm in an ideal sleep environment

A predictable pattern helps signal sleep for your baby.

This can be as simple as:

1. bring baby into the nursery
2. diaper change
3. swaddle
4. for older babies, you can include a book
5. turn on a sound machine
6. turn off the light
7. settling baby

Consistency makes sleep feel more familiar and less abrupt. This can be a one-minute routine or a 15-minute routine, but doing things in the same order will help your baby cue in for sleep earlier.

*This is part of why we recommend practicing crib naps right from the start. Yes your baby *might* fall asleep in the middle of a busy living room, but there will come a day when they are fighting sleep and having routines in place benefits everyone involved!*

4. Use layered support

If your baby is truly overtired, you might need to bring out the big guns.

Examples of high-intensive support that can get most babies to sleep:

• Standing and bouncing or swaying in a completely black room with loud white noise. If you can’t get the room completely black, cover the baby’s eyes with your hand or a hat. [Remove hat after they fall asleep].
• Bouncing on an exercise ball…you guessed it in a completely black room with loud white noise.
• Taking a ride in the car

None of these methods for getting the baby to sleep is sustainable in the long term. If done for multiple naps/bedtime for multiple days, your baby will expect these methods for future sleep. Only go to these as a last resort after trying other sleep steps.

Remember, this is simply an emergency band-aid to get your overtired baby to sleep, and then you can work on teaching them independent sleep.

My newborn still won’t fall asleep [but they aren’t overtired]

If your baby was never overtired to begin with, or if you’ve remedied the overtiredness and are still in a position where your baby won’t fall asleep, there may be other things at play.

1. You are missing their ideal sleep window. You may be putting them down slightly too early or slightly too late. Try tweaking the window and seeing what helps.
2. They may be particular. I once had a baby not sleep because she would stare at the indicator light on her humidifier. Check that the temperature, light, sound and overall sleep environment is set up for sleep.
3. Is your baby being swaddled?
   • If no: Swaddle them!
   • If yes: Swaddle them tighter [example here] or try a looser option [example here].
4. Is your baby being held for sleep?
   • If yes: They might actually be looking for some space and independence. Try the sleep steps and putting them to sleep in their sleep space.
   • If no: Are you just laying them down in their space and expecting them to sleep? Newborns need to be taught independent sleep, it doesn’t come naturally to them.

When Extra Support Helps

When a baby consistently fights sleep, it can quickly become exhausting.

Overnight support allows sleep patterns to be worked on consistently while ensuring parents get the rest they need.

At Well Supported Family, our team provides responsive overnight care, implements sleep conditioning, and helps babies settle more easily.

We can also have a team member come in for a daytime shift to show parents what a wake window and independent naps look like, or simply to give parents a break.

Additionally, if parents need an overhaul. We do offer 30-day virtual sleep conditioning programs where we work 1:1 with parents to help find the root cause of why their newborn fights sleep and how to find solutions that work for their family.

Final Thoughts

If your baby is fighting sleep, it does not mean they are not tired.

It usually means they are too tired.

With earlier timing, consistent support, and a gentle approach, most babies begin to settle more easily over time.
