Why Do Babies Fight Sleep?

Estimated time to read 8 minutes

Sleep plays an important role in your baby’s mental and physical development. Not to mention, any parent understands how precious those moments are when your baby is sleeping peacefully and you can finally relax or catch up on all your household chores.

But, when your baby is fighting sleep, whether it be naps or bedtime, it can be frustrating for both you and your little one—not to mention exhausting. If this sounds familiar, don't worry—you're not alone. Many parents go through this struggle.

But why does my baby fight sleep? Read on to learn more about the possible explanations and how you can help your little one get the rest they need.

Why Do Babies Fight Sleep? 12 Possible Reasons

There are actually a number of reasons why a baby might be fighting sleep. Understanding why your little one is struggling to fall asleep and stay asleep can help you address the underlying issue and get them the rest they need. Here are 12 possible reasons:

1. Overstimulation

It’s easy for a baby to get overstimulated since everything is new and fascinating to them. Overstimulation can stem from loud toys, screens, bright lights, or lots of movement.

2. Separation anxiety

If your baby is used to being held or rocked to sleep, they may resist going to sleep on their own in their crib.

3. Circadian rhythm

Babies have their own internal clocks, known as circadian rhythms. Unfortunately, babies aren’t born with strong circadian rhythms—meaning your baby will need to establish a healthy circadian rhythm after they are born. Until then, it could mean your little one has their nights and days mixed up.

4. Hunger

Babies have tiny tummies and need to eat frequently. As a result, it’s common for babies to have trouble falling asleep or waking throughout the night (and day) once their body starts to send those hunger signals.

5. Blood sugar spikes or crashes

Diet plays a big role in sleep. Sugary foods lead to blood sugar spikes and crashes that interfere with sleep.

6. Illness

Your baby may sleep more when they aren’t feeling well, but they can also have difficulty falling asleep and staying asleep when they are feeling under the weather.

7. Sleep regression

As your baby grows and develops, fighting sleep may occur more often. This is known as child sleep regression, and although it’s completely normal, it can make it more difficult for parents.

8. Traveling

Traveling can affect your circadian rhythm, and your baby might struggle with changes in surroundings. Babies like predictable routines, and new environments can disrupt their sleep.

9. Teething

The teething process usually begins around 4-6 months of age, which can be uncomfortable and make it difficult for your baby to get restful sleep.

10. Discomfort

Various discomforts, such as gas pain, teething pain, or an uncomfortable position, can wake your baby up in the middle of the night.

11. Environment interruptions

Room temperature, light, or noise can all make it harder for babies to fall asleep and stay asleep.

12. Overtired or under-tired baby

Babies who are overtired or under-tired can struggle to fall asleep or stay asleep.

How Can You Help Your Baby Sleep?

Depending on the underlying cause of your little one’s refusal to sleep, there are several ways to help your baby stop fighting sleep and get a little more shut-eye:

Tip 1: Help your baby distinguish between day and night

Help your little one develop a healthy circadian rhythm early on by teaching them that daytime is for play and nighttime is for calm and sleep.

Tip 2: Establish a nap and bedtime routine

A consistent routine signals to your baby that it’s time to wind down for the night, aiding in better sleep.

Tip 3: Identify signs that your baby is ready to sleep

Tired signs like flushed brows, staring, eye rubbing, and yawning can help you determine when your baby is sleepy.

Tip 4: Shut off electronic devices two hours before bed

Electronic devices can be very stimulating for babies, disrupting sleep.

Tip 5: Create a restful environment

A dark, quiet room at a comfortable temperature can encourage better sleep for your baby.

Tip 6: Feed your baby a well-balanced diet

Focus on providing a balanced diet that includes protein and healthy fats, as sugary foods can interfere with sleep.

Tip 7: Read a “sleep training” book

Sleep training can provide structure and planning to the process, which may help in determining what works best for your family.

Tip 8: Try baby wearing for contact naps

Baby wearing helps babies fall and stay asleep, mimicking the womb's environment.

Tip 9: Use a swaddle or sleep sack

Swaddling or using a sleep sack can help your baby feel secure and comfortable while sleeping.

Tip 10: Recognize when your baby is ready to drop one of their naps

If your baby consistently doesn’t seem tired at naptime, it might be time to consider dropping one of their naps.

Tips for Tired Moms

Give yourself some grace

Cut yourself some slack; you’re doing the best you can.

Sleep when the baby sleeps

Try to get rest whenever your baby naps to combat sleep deprivation.

Practice self-care while your baby sleeps

Make time for yourself, even if just a few minutes each day.

Ask for help

Don’t hesitate to ask partners or family members for support with childcare and housework.

Conclusion

It’s common for babies to go through phases of refusing to sleep. Fortunately, many solutions exist to help both you and your baby get the rest you need. Remember, every baby is different—be patient and try different solutions until you find the best fit for you and your baby.
