Baby Spitting Up Clear Liquid: 12 Surprising Reasons You Should Know

Are you worried why your baby is spitting up clear liquid? You notice that she never runs out of it no matter how she kept on doing it the whole day. Actually, it is not unusual to see them spit. In this article, we are going to find out why they spit and learn some mom facts behind it.


Baby spits usually are saliva, water, milk or a combination of all. Spitting up happens when the food intakes of the baby, go back up and out to her mouth. This should not be a problem if it just goes with minimal volume. However, if your baby frequently spits with a larger amount, it may impose problem in her nutrition. She might not be getting the right amount of food crucial for her development. Watch out for weight loss.

But do you know what’s causing them to spit? Here are reasons behind that every mom should know.

1. Undeveloped LES

There is this valve between the esophagus and the stomach that keeps whatever we swallow down. For babies, it is not yet fully developed.

Usually, it takes the whole 12 months for it to develop fully. Along with your baby’s growth, that valve will fully develop. You call this valve LES, meaning, Lower Esophageal Sphincter.

2. Overfeeding

Babies have a very small stomach. When we overfeed them, it will overflow back up. That is why they spit it out. You call this process Functional Infant Regurgitation.

The length of time and the amount of feeding would continue to change as your baby grows. Follow a certain personal program to give your baby the correct amount of milk for her age. The younger your baby is, the shorter time and the lesser volume of milk she will need.

When a baby is full, do not give them many physical activities to prevent them from spitting.

3. Burping

Burping is releasing unwanted gas bubbles through the esophagus then out to your baby’s mouth. Most of the time, these bubbles bring along with them liquids from down as it goes out, thus the spitting of babies. When it does, that is the time that you call it, Wet Burps

Learn to burp you baby the proper way. There are different ways to burp your baby. Do it against your shoulder, pressing her stomach in sitting position, and let her lay down on her stomach.

For better comfort, make sure you have a bunch of burp cloths around, as you will need many of them. You can buy them in bulk from amazon, or you can always improvise by using a towel. From my own experience, however, you will run out of towels, very fast. 

4. A Cough, Cold and Sneezes

Babies who have a cough and cold may spit up clear liquid frequently. When they cough, especially after they have just been fed, milk tends to come up from the stomach and goes out from the mouth. This is because their small stomach contracts with every cough they take. 

Most of the time, it will only be saliva, like when they are sneezing. But when your baby gets a cold, she will have the tendency to swallow the mucus, and will have a reaction trying to spit it out as well.

5. Teething

​When babies are teething, saliva is produced more than the normal amount. This is the body’s aid for the pain of a growing tooth. It helps cool off and soothe inflamed and tender gums. However, too much saliva causes excessive drooling thus the tendency of a baby spitting up clear liquids.

Make sure you have few teethers around for when this happens, because your baby will be in pain, and it is now when he will start biting you, or even worse, his sibling. 

6. GERD- Gastroesophageal Reflux Disease

This condition causes your baby to spit up clear liquid in large amounts that it gives throat pains and abnormality in breathing. Symptoms like gagging, pain and waking up screaming. Spitting up are also called physiological or uncomplicated reflux. You should contact your pediatrician whenever you are worried. Never try to diagnose your baby all by yourself, unless you are, of course, a medical staff.  

7. Sleeping Position

Frequent spitting up especially with larger amounts happens when you have not put her in the proper position during sleeping. Spitting up may prevent her from breathing.

When lying down, there is a great possibility that spits will go out to the mouth and the nose as well. Most likely it will lead to choking your baby while sleeping. This is a very critical situation that you should be focusing on. Prevent SIDS in all situations.

Make sure you baby sleeps in the proper position, at all times. If you are not sure about what is the best place and position for your baby to sleep in, do not hesitate to contact your health nurse/pediatrician/midwives for help and support. 

8. Pyloric Stenosis

This is an abnormality that occurs when your baby’s stomach muscles are too big to let the food pass through. When the muscles contracts, the liquid coming in will shoot up back where it came from. This forceful spitting of liquid may be a result of medical reaction from antibiotics taken by moms as medication. 

9. Mother’s Diet

One cause of baby spitting up clear liquid is the allergy of dairy products. There are two ways wherein babies can get those allergies. It could be the milk formula that you have chosen to feed her or the diet you as a mother is having. Baby formula can easily be corrected, right?

However, for mothers, this could be a little bit complicated. Concerned moms drastically change their diet pattern as soon as they found out about allergic reactions of their infants. To help you with this, you need to follow some diet programs that would be recommended by your pediatrician. In the case of uncontrollable baby spitting, it is time to call a doctor. 

I had this happen with my daughter, and I had to watch my diet until I finished breastfeeding, which was until 6 months ago (she was 17 months old). Now, I make sure she does not drink milk, or eat diary products that will upset her stomach. The frustration here is that she is not completely allergic to milk/diaries, she can take just fine some types of milk, and others are a total disaster, so it is quite a challenge for me to get the right milk for her when we travel abroad. 

10. Proper Feeding Position

Baby spitting up clear liquid may occur if you are not feeding your baby in the proper position. There are several methods on how to feed your baby. The two popular methods are the breastfeeding method or the choice of bottle feeding. 

Whichever application you decide, there is always a proper position on how to do it. Other not commonly methods are syringe, spoon, cup and SNS finger feeding. Learn to prevent your baby’s spitting up.

After feeding, be sure to let your baby sleep in the proper position to prevent choking.

I cannot stress enough how important is, in case you bottle feed your baby, the type of the milk bottle you use. With my first son, I did not know better, and I bought a normal milk bottle, and he would always inhale air while drinking. He had an upset tummy for the first 6 months, crying at night, and all the package. With my daughter, because she was breastfed, I started to look around to find a special type of bottle that will emulate the breast sucking method. And it is then that I found the "magical" milk bottle, that not only helped her to not "forget" how to breastfeed, but also helped her tremendously with the air inhalation while her father was feeding her.

I am including here a link to amazon where you can  find the bottle that I am talking about, which I totally recommend that every mom should have. Even if you chose to breastfeed (like I did), there will be times, when the father or someone else in the family will have to take care of the "meal" for you, and then you need a bottle, where the baby can drinking from, your on breast milk.

11. Baby Bottles

​There are lots to consider when buying baby bottles. You should know that every age of the baby, there is a corresponding bottle that fits for her use?

Before buying, consider the age of your baby, and you will find out that the younger the baby, the smaller the bottle and the hole of the nipple as well.

Avoid using big bottles for your baby. The milk will flow fast in larger amounts it would take her a hard time swallowing; this will result to constant spitting of liquid or even lead to chocking.

Again, here again, I recommend the Medela Calma breast milk bottle.

12. Baby Diapers

​Baby Diapers plays an important role for your growing baby. Choose the diaper that is best for your baby’s age. Using small size diapers for your large baby will give her lots of discomforts. One major problem is the pressure it causes in the abdomen.

Once you feed the baby, the diaper pressure is overwhelming; it will let your baby spit out. Find the right diaper size for your baby.
