Why Is My Baby Is Bloated?

You keep saying to yourself, “My baby is bloated.” If you have been noticing this for quite some time, you should always feel confident in deciding to reach out to your pediatrician for their opinion.

Getting to the source of your baby’s bloated appearance is important for your baby’s health. Yes, being bloated is common among adults.

However, don’t treat your baby’s health issues like you would your own. It is best for you to know for certain as to the reason(s) why your little one always appears to be bloated.

In fact, any time you have a concern about your little one, it is best for you and your baby to know for certain that they are okay.

If you are waiting to get in with your pediatrician or waiting to hear back, below you will find nine possible reasons as to why your baby is bloated:

1. Continuous Crying

All babies zero to three months in age may have bouts with excessive crying, but did you know that continuous crying can be the reason your baby is bloated?

When your baby cries a lot, they sometimes take in too much air. All that extra intake of air during crying spells can get trapped in your baby’s belly and lead to bloating.

You should know though; there are all kinds of strategies to help with your baby’s prolonged crying spells.

2. Constipation

If your baby is constipated, they could end up being bloated because of that.

When your baby is not passing bowels regularly (or if their stools are harder than usual) then the bloating could indeed be due to your baby’s constipation.

Your baby could be crying more than usual as a result, too. As you just read with potential reason number one, excessive crying can lead to bloating.

With constipation, your baby will already have some bloating. The accompanying crying will only make your baby’s bloating worse.

Constipation is by far one of the most common reasons as to why your baby is bloated.

3. Nursing Positions

If your child is not latching on correctly during breastfeeding, too much air can slip in and cause your baby to be bloated.

You must pay close attention to how your baby is feeding and how they respond to feedings. If you notice your baby is bloated mostly after feedings, you must reconsider feeding positions.

If breastfeeding is indeed causing your baby to become bloated, there are several positions you can try that might mitigate breastfeeding-related bloating with your baby.

4. Digestion Development

As your baby grows, they will learn how to handle and digest foods in their own unique way specific to their unique body.

New food introductions or prolonged use of certain foods can cause your baby to have to change their digestion processes.

Babies change their processes and preferences often in their first few months of life.

You should already know that solid foods are not good for their digestive system until your pediatrician approves them.

As a rule of thumb, your baby will not be able to digest solid foods until they are six months old. Failure to follow your pediatrician’s dietary guidelines can lead to your baby being bloated.

5. Lactose Intolerant

Diarrhea and gas are two signs that your baby could be lactose intolerant.

You should also know that bloating can be a sign. Were you aware that lactose allergies and milk allergies are not the same things?

If you didn’t, don’t worry… most people aren’t aware. In fact, milk allergies impact the immune system while lactose intolerance impacts the digestive system.

6. Food Allergies

Milk is only one of the food allergies that your baby might develop. Eggs, peanut products, soy, wheat, fish and shellfish are other common baby food allergies.

If certain foods cause your baby to be bloated, it could be because your baby is allergic to those foods.

You must check with your baby’s pediatrician for the final say-so on what your baby can and cannot eat. Bringing your baby to an allergist is also a good step.

7. Gas

Gas is one of the more obvious reasons as to why your baby is bloated.

When your baby has excessive gas, the gas can get trapped in their intestines. You will not only notice they are bloated, but you will also recognize the pressure at their abdomen.

Gas is no cause for alarm on your end. It is not uncommon for your baby to pass gas between 13 and 21 times a day.

There are innumerable great resources with valuable information out there to help with your gassy baby.

8. Excessive Pacifier Use

Your baby’s pacifier is sometimes your go-to crutch to get you through the day.

This is especially true if your baby is being extra fussy and crying more than usual. It is sometimes the only thing you can find to soothe their nerves and calm them down.

Did you know that excessive pacifier use can cause your baby to become bloated?

Your baby’s excessive sucking can cause air to get trapped in their belly. When that air gets trapped, your baby can become bloated.

If you have ruled out everything else, your little one staring at you with his pacifier in his mouth might be alerting you as to the real reason for his bloated stomach.

9. Anxiety

If your baby is dealing with anxiety, the stress of it all can make them gasp for air.

When babies get anxious, they are prone to gasp and swallow access air that can lead to bloating.

You must remember that little ones are super delicate. Even the slightest changes can cause a baby to become anxious.

Of all the reasons your baby could be anxious, separation anxiety is one of the leading potential causes. Separation anxiety can start as early as four-months-old and continue until age three.


Above you have discovered nine possible reasons as to why your baby is bloated. Of course, there may be other reasons, but the nine reasons listed above are the most common.

The final say-so must come from your pediatrician. Sure, your baby’s little bloated bellow might be cute at first. However, if it fails to go away, it could point to a serious health problem or the development of a future health problem.

Don’t take the chance! Check with your baby’s medical provider to be sure.

  1. My baby never slept well (especially through the night) until I started using the website – that website has been by far one of the best things I’ve ever got my hands on to get him to fall asleep quickly. Best time is 45 seconds from awake to asleep! Can’t imagine life without it! I heard about it through a kindergarten teacher who uses it to put to sleep a group of 30 children. Check it out! SLEEPBABY.ORG 🙂 Best of luck to you and your family!

  2. If your baby won’t sleep, check out the sleep method from – Thank you SleepBaby for this brilliant method! My daughter now sleeps from 7pm to 6 or 6:30am every night with almost no night wakings. And even if she wakes, it’s usually just for a second and then she falls back asleep all on her own.

    Most nights I get my 8 hours of sleep and it’s just wonderful! I really feel like I understand her little body and mind and can address her sleeping holistically. I can’t thank you enough, Kacey and the team!

  3. Our son now sleeps through the night because of!

    Our baby had trouble sleeping through the night from the time we brought him home from the hospital. We tried changing his formula and even putting his crib in our bedroom. Nothing I tried before SleepBaby worked. The night after I started using, he started sleeping for several hours at a time.

    I really enjoyed the tips on how to make my baby laugh. I love hearing him laugh and I think SleepBaby’s laughter tips help relax him so it’s easier for him to sleep. Oh! And I also liked the instructions about how to create the right environment in his room that’s relaxing.
