Is Your Baby Spitting Up a Lot? Causes and Solutions
Do you feel like you spend more time doing laundry than with your newborn? Baby spitting up is truly annoying.
Although it may seem like a lot of milk reflux, this is usually a normal process of baby development. Let's go understand why this happens and how to deal with it to keep your child clean and comfortable.
What Causes Spitting Up?
By looking at the anatomy, you can understand why your baby spits up. Each of us has a muscle at the bottom of our esophagus (the tube that connects our mouth to stomach) called the lower esophageal sphincter. Think of this muscle as a valve or a door. It opens to let food into the stomach and then closes tightly to hold the food while we eat.
This muscle in newborns is not yet fully developed. It's a bit flimsy and too easy to relax. When the "door" pops open when it shouldn't, milk and stomach acid flow backwards into the esophagus and eventually out of the mouth.
This is called gastroesophageal reflux.
In addition, babies have very small stomachs – about the size of a cherry at birth and apricots at one month – so it's easy to eat too much, which forces excess fluid backwards.
Normal vs. Excessive Spit-Up: What's Considered Typical?
It can be startling to see milk come back up, but in most cases, it is a "laundry problem," not a medical problem. Doctors often refer to babies who spit up frequently but are otherwise healthy as "Happy Spitters."
Frequency: It is normal for babies to spit up several times a day, often right after feeding or during burping.
Age: Spitting up usually peaks around 4 months of age. As your baby starts sitting upright and eating solid foods (around 6 months), the muscles get stronger, and the issue usually resolves itself by the time they turn one.
Behavior: If your baby smiles, coos, and seems content immediately after spitting up, and they are gaining weight steadily, it is generally considered normal reflux.
However, if the spitting up seems to cause your baby pain, or if they arch their back and cry during feedings, it might be a sign of something more uncomfortable, like GERD (Gastroesophageal Reflux Disease).
How to Reduce Spit-Up: 7 Practical Feeding Techniques
While you cannot force the esophageal muscle to grow faster, you can change how you feed your baby to keep the milk down. Here are seven effective strategies:
Choosing the Right Bottles to Minimize Spit-Up
The equipment you use plays a massive role in how much air your baby swallows. Choosing the right bottle is one of the most effective ways to reduce gas and spit-up.
You might ask, what is an anti colic bottle? Simply put, it is a bottle designed to prevent a vacuum from forming inside the container. In standard bottles, as a baby drinks, a vacuum is created that forces the baby to suck harder. This often leads to the baby detaching from the nipple to let air rush in, or sucking in air along with the milk.
How do anti colic bottles work? They utilize a venting system—either a tube inside the bottle or vents in the base/nipple—that allows air to enter the bottle to replace the milk being drunk. This air bypasses the milk and goes to the back of the bottle. By separating the air from the liquid, these bottles ensure your baby swallows milk, not bubbles. This reduction in air intake lowers the pressure in the stomach, reducing the likelihood of spit-up.
The shape of the nipple matters just as much as the vent. A nipple that mimics the natural shape of a mother's breast allows for a better latch. A poor latch creates gaps at the corners of the mouth where air can sneak in. Furthermore, matching the flow rate to your baby's age is vital. Slow flow bottles for newborns prevent the baby from being flooded with milk, which can cause choking and immediate regurgitation.
Meet Thyseed
If you are looking for a bottle that combines all these features, the Thyseed Glass Natural Anti-colic Baby Bottle is an excellent option for parents focused on safety and comfort.
Unlike standard bottles, Thyseed features a patented bottom vent system. This design ensures true air-liquid separation, meaning air enters from the bottom and never mixes with the milk your baby drinks. This significantly reduces the gas and bubbles that lead to spit-up.
Beyond the vent, the bottle uses a skin-tone, breast-like nipple made from food-grade liquid silicone (developed with Wacker, Germany). It is designed to feel and flex just like mom, encouraging a secure latch that prevents air intake. Plus, with slow flow options tailored specifically for newborns, it helps control the pace of feeding. The bottle body is made from high-quality borosilicate glass or PPSU, ensuring that what goes into your baby's mouth is pure, safe, and free from harmful chemicals.
Spit-Up vs. Vomiting: How to Tell the Critical Difference
It is important to know when a mess is just a mess, and when it is a symptom of illness. Vomiting is more forceful than spitting up and is usually a sign that the body is trying to expel something.
Here is a comparison to help you spot the difference:
| Feature | Spitting Up (Reflux) | Vomiting |
|---|---|---|
| Force | Flows easily out of the mouth; effortless. | Forceful projection (projectile); shoots out. |
| Mood | Baby looks happy or normal; "Happy Spitter." | Baby looks distressed, cries, or looks in pain. |
| Timing | Usually happens right after feeding or burping. | Can happen anytime; often repeated. |
| Volume | Usually a small amount (1-2 tablespoons). | Larger volume; often empties the stomach. |
| Content | Looks like milk or slightly curdled milk. | May contain bile (greenish) or digested food. |
While spit-up is normal, you should contact your pediatrician if your baby exhibits any of the following symptoms:
Key Takeaways
Conclusion
Dealing with constant spit-up is a messy phase of parenthood, but remember that it is temporary. By adjusting your feeding techniques and choosing the right gear, you can make feeding time much calmer. Focus on keeping your baby upright and minimizing air intake to see improvements. For a feeding experience that prioritizes safety and reduces gas, consider trying Thyseed bottles. We are here to support your journey with products designed for love and built for safety.
FAQs About Baby Spitting Up
Not necessarily. However, some babies may have a sensitivity to cow's milk protein found in standard formulas. If you suspect an allergy, consult your doctor. Also, formula takes slightly longer to digest than breastmilk, which keeps the stomach full longer.
While anti colic baby bottles are highly effective at reducing the amount of air a baby swallows (which reduces gas-propelled spit-up), they cannot change the baby's physical anatomy. Some spit-up may still happen until the baby's muscles mature, but the frequency and discomfort should decrease.
For most babies, spitting up slows down significantly by 6 months when they start sitting up and eating solids. It usually stops completely by 12 months.
In the past, this was common advice. However, adding cereal to a bottle can increase the risk of choking and excessive weight gain. You should only do this if specifically advised by your pediatrician.
