Why Is My Baby Spitting Up? Understanding Baby Reflux

When you have a newborn baby, it can be overwhelming to get yourself acquainted with this squirming new bundle. If your little one is struggling to feed, or spitting up after a feed, you may be getting worried.

Is spitting up just something babies do? Or does it signal a more serious problem?

It’s normal to be anxious about these things, especially for first-time parents. Let’s look into what causes reflux and spit up in babies, how to distinguish between spit up and vomit, and how to treat reflux.

Learning more about these issues will make you more confident and set your mind at ease.


Why Is My Baby Spitting Up?

Nobody wants to see their baby in discomfort. As vomiting in adults is generally a sign of illness, it can be alarming to see your little one bringing their food back up. However, don’t worry just yet. It is more common than you think.

Is It Normal?

Spitting up is common in babies and, in most cases, is completely normal (source). It is most likely to happen right after feeding, though it may also occur up to one or two hours later. It’s more of a laundry problem than a medical one.

Most babies outgrow spitting up as they get older. The condition is typically at its worst when baby is around two to four months old.

By their first birthday, most babies stop spitting up altogether (source). So, don’t worry- it will get better!

Causes of Spit Up

Spit up most often happens because your little one’s digestive system is still developing. As they mature, babies will become much better at keeping their food down (source).

In addition to their developing digestive system, there may be a few other factors causing excessive spit up. These include:

  • Oversupply of breast milk: This may cause your baby to take too much milk or drink it too quickly. The result is reflux-like symptoms. Thankfully, it is easy to remedy (source).
  • GERD: If your baby is spitting up a lot, it may be a sign of gastroesophageal reflux disease. We’ll talk more about GERD below.
  • Food sensitivities: In breastfeeding moms, this could be from something you ate. If you are no longer breastfeeding, any new food could disagree with baby’s stomach.

The most common cause of food sensitivities in babies is an intolerance to cow’s milk. However, pay attention to whatever you feed them, especially if you’re introducing solids like baby cereals or soft foods.

If you are still breastfeeding, elements of your diet can also upset your baby’s stomach. Reflect on your food intake if they’re spitting up more than usual. You may have eaten something different, which has transferred to baby through your breast milk. (Allergy to something in your milk is typically accompanied by more than just spitting up, though.)

Medication and alcohol can also affect breast milk, so look into those factors too. However, neither of these are typically a cause for concern, as long as your little one is otherwise happy and gaining weight.

Identifying Spit Up

Spit up will usually look like what your baby has recently eaten. If they’ve just had a milk feed, it should be creamy and pale in color. It might be a thicker consistency if they ate solids, for example, baby cereal.

If their spit up is a different color, like green, think of their last meal. If they had pureed greens, then all is likely to be normal.

When to See a Doctor

Regular spit up is not forceful. Vomiting is normal once in a while. However, if your little one is repeatedly vomiting violently, then you should seek medical advice.

If baby’s spit up is green, yellow, or with traces of red, which isn’t from their last meal, consult a doctor immediately. Also, if baby is not gaining weight and is uncomfortable or distressed, seek medical advice.

Remember

Spit up should look like whatever your baby has just eaten. Spitting up is also effortlessly bringing back up food. If your baby is forcefully ejecting food, or a strangely-colored substance, seek medical assistance.

What Is GERD?

While spit up is normal, even expected in young babies, a small percentage of babies may experience extra discomfort.

GERD, or gastroesophageal reflux disease, is a more complicated form of spitting up. There are a few key indicators of reflux in your baby, but your doctor will need to diagnose this condition (source).

Symptoms of Baby Reflux

Most signs of GERD will be frequent and persistent. Monitor your baby closely and keep track of symptoms and potential triggers to avoid falsely assuming they have reflux disease (source).

Some indicators your little one may be suffering from reflux include:

  • Feeding difficulties, including gagging, refusing feeds, or choking.
  • Constantly spitting up milk during or after a feed, throughout the day.
  • Regularly suffering from chest infections.
  • Crying while feeding, or constantly crying.
  • Constant hiccups or coughing.

Is Reflux Dangerous?

Generally speaking, reflux is not a major cause for concern. As long as your baby seems happy, healthy and is gaining weight, you don’t need to seek medical intervention.

However, if new symptoms appear after six months of age, you may want to contact your doctor for advice.

Speak to your doctor or pediatrician if you begin to grow concerned for any reason. Particularly if your little one is continuing to spit up past age one and has any of the following symptoms (source):

  • Refusing to feed or spitting up frequently.
  • Gagging or coughing during a feed.
  • Irritability or crying more than usual.
  • Yellow or green vomit.
  • Frequent projectile vomiting.
  • Blood in their vomit or stools.
  • Tender or swollen stomach.
  • Weight loss, or failure to gain weight.
  • Fever or high temperature: 100.4 Fahrenheit or higher is a fever.

These symptoms can help the specialist diagnose the underlying cause. It is likely your baby will need tests or treatment if they have one or more of these symptoms, combined with spit up.

What About Silent Reflux?

This condition is more difficult to notice, as your baby will not spit up. With silent reflux, the stomach contents travel back up to the esophagus and are then re-swallowed. There is pain and discomfort, but no vomiting (source).

You may be able to identify silent reflux if baby frequently coughs or hiccups during feeds. They may also be particularly fussy or show discomfort when feeding.

How to Prevent Reflux

If your baby is gaining weight at a healthy rate, reflux will not normally require any treatment. Still, it is important to provide relief where possible, or even prevent reflux altogether. Here are some remedies you can try to prevent reflux and spit up in your baby.

1. Adjust Your Feeding Technique

The way you feed your little one could be causing some problems. Babies shouldn’t be completely horizontal during a feed; elevate their head slightly. Even during bottle feeds, hold baby in the same position you would if you were breastfeeding.

Regularly burp your baby during and after every feed. This can be done by sitting them upright and gently rubbing their back. Hold them in an upright position for a short while after feeding to release any trapped gas.

Make sure baby also isn’t swallowing air during feeds. The nipple of a bottle should always be kept full, by holding the bottle at an angle, preventing air bubbles.

If breastfeeding, make sure baby is latched on correctly, and not gulping air as they suck.

If you are no longer breastfeeding, try a thicker milk formula. If the milk is thicker, it is less likely to be brought back up.

However, unless your baby has already been introduced to solid food, ask a doctor for advice specific to your baby. Some thicker formulas are only available on prescription and may cause baby to gain weight quickly.

2. Create a Structured Feeding Schedule

Changing baby’s feeding routine could reduce spit up and reflux. Try giving them smaller amounts more often. That way, it’s easier to digest and keep down (source).

Try to feed at the same times throughout the day to get your baby into a feeding routine. Also, make feeding times a quiet, nurturing, and relaxing experience.

Babies can sense it if you are tense. So while you may be concerned about your baby, try to relax. Give your little one time to feed at a slower pace.

3. Check Sleeping Position

Babies can find it difficult to settle if they are in pain following a feed. Adjusting their sleeping position may help ease these feelings.

Place a wedge beneath the head of the mattress to elevate their upper body. There are a variety of products for this, but be sure you are only using one on the advice of your baby’s doctor. The wedge should always go under the mattress, not directly under the baby or sheet.

4. Care and Comfort

It’s important your baby feels calm and cared for at all times, to prevent a negative association with feeding and sleeping. While you may be itching to get your little one into a regular routine, remember, reflux doesn’t last forever.

You may have to sacrifice a little more sleep during this period. However, as babies grow out of their reflux, they can establish a better sleep pattern.

External Factors When Breastfeeding

If you are breastfeeding, certain lifestyle factors can aggravate GERD. Below are some factors which could irritate your baby and affect your milk supply.

1. Caffeine

If your baby has reflux, watch the amount of caffeine you consume while breastfeeding. If you have a high intake of caffeine in your diet, your little one may suffer.

The LES (lower esophageal sphincter) is a muscle which allows food to move from the esophagus to the stomach. In babies, this is not fully developed. Caffeine can relax this muscle and allow food to go in the opposite direction, causing spit up.

While you may be dependent on caffeine to get you through long days, and even longer sleepless nights, consider cutting back. Try to limit your intake to no more than two cups of tea or coffee a day, or — better still — switch to decaf (source).

2. Alcohol

Alcohol can also cause the LES to relax. Therefore, it carries the same risks as caffeine.
If possible, do not breastfeed for at least two hours after you have alcohol. If you’ve only had one drink, most of the alcohol will be out of your system by then. ‘Pumping and dumping’ will not eliminate alcohol from your milk any faster.

3. Smoking

Smoking is another external factor which can cause reflux in breastfed babies. Nicotine in the cigarettes passes into the mother’s milk. It stimulates the production of gastric acid and, as with caffeine or alcohol, opens the LES.

Studies have revealed many other negative effects of nicotine on babies (source). The best way to avoid these problems when breastfeeding is to stop smoking. Even if you are not breastfeeding, second hand smoke is dangerous for your baby and can make reflux symptoms worse for baby.

Take Note

If you are unable to stop smoking while breastfeeding, try cutting down as much as possible. Smoking after a feed as opposed to just before will also reduce baby’s intake. It takes around 95 minutes for half of the nicotine from a cigarette to leave your body.

4. Test for Allergies

In cases where reflux is caused by an allergy to cow’s milk, your baby may also have diarrhea, blood or mucus in their stools, and a rash.

It’s common for babies to grow out of this allergy. However, the condition can also be treated by removing dairy products from their diet (source). Your doctor will recommend any relevant tests if they suspect a milk allergy.

If you recently introduced solid foods to baby’s diet, the reflux may be signs of intolerance to these foods. It’s a good idea to keep a diary of the food you introduce to your baby. This makes it easier to track their symptoms and reactions.

Treatments and Remedies

It may feel like there’s no respite when it comes to your little one spitting up. Fear not, there are a few simple things that may work for you. Here are some solutions you can try:

1. Gripe Water

Gripe water is an herbal-based product used to relieve the discomfort from gas and indigestion for babies. The ingredients vary slightly within different gripe water brands.

Whether you find success with gripe water depends on your baby. Some parents love it and find it helpful, whereas others have seen no change. Personally, it worked for my babies, so I love it!

Babies can use gripe water from month one of age and up. Although it is a natural treatment, carefully follow the instructions and dosage on the label. If you have any concerns about using gripe water, ask your doctor for more advice.

2. Baby Cereal

Thickening your baby’s feed may reduce spit up and reflux as it is easier to keep down. The option is worth looking into, as long as your baby is over three months of age. If you plan to do this, work closely with your baby’s healthcare provider.

To thicken your little one’s formula or expressed breastmilk, use up to one tablespoon of baby rice or cereal for every two ounces of formula. The thicker formula means you’ll need larger size nipples. Alternatively, cut a small ‘X’ into the end of the nipple (source).

Either way, ensure the mixture is flowing through smoothly. There are also pre-thickened formulas available to buy if you don’t want to mix your own.

Remember

Adding cereals and rice to your baby’s formula increases the calorie content, which you may want to avoid if your baby is overweight. Consult your doctor for advice if you have any doubts about this method.

3. Medication

Medication is rarely necessary to treat reflux, except in severe cases. Two common medications used to treat reflux are:

  • Alginates: These create a protective barrier over the stomach and prevent anything coming back up from the stomach. They also prevent irritation to the esophagus. You’ll receive alginates if you have already tried to change the way your baby feeds. If these changes have not relieved symptoms, alginates may be effective.
  • H2-receptor antagonists and proton pump inhibitors: Both reduce the amount of acid within the stomach. This prevents the stomach contents from irritating the esophagus and stops any reflux or spit up. These medications are usually recommended to relieve discomfort. If your baby is refusing to feed or appears uncomfortable during a feed, they may help.

Frequently Asked Questions

Spit up will only cause a rash or acne if it is linked to an underlying health issue. The most common cause of a rash related to spit up is an allergy to cow’s milk. Consult your doctor if you suspect your baby may be allergic to their formula.

In some cases, your baby may find relief from spit up or GERD by being placed on their stomach. However, only use this position with full supervision.

Take Note

Only let babies lie on their stomach while they’re awake and supervised. Allowing children under one sleep on their stomach is strongly discouraged, due to the risk of sudden infant death syndrome (SIDS) (source).

While you may be worried your baby might choke if they spit up in their sleep, this is unlikely to be fatal. A baby can automatically cough up or swallow spit up fluid. This is a reflex designed to keep the airways clear (source).

In some cases, baby reflux can worsen at night, for example, in babies who lie on their backs and cannot get relief. This causes disturbed sleep and increased irritability.

Speaking of sleep, reflux may seem worse through the night, due to your own sleep deprivation. Small problems can feel a hundred times bigger when you haven’t slept properly in weeks.

It’s common for babies to experience some reflux within the first three months of their life. But if baby was feeding well beforehand, it may feel like it has suddenly come on.

If you have noticed a sudden change in your baby’s health or character at the same time as the reflux began, you should seek medical advice. It’s always best to err on the side of caution, especially if your baby is in great discomfort.

You may find the reflux comes and goes in bouts, too. This can be due to changes in your diet if you are breastfeeding. Your baby may also experience reflux when changing from breastmilk to formula.

Babies sometimes develop reflux if you change the baby formula, or when you begin to introduce solid foods. Keeping track of changes to baby’s diet and new foods being introduced will help you monitor any new symptoms.

You may find as they get older, they’re able to tolerate food they seemed to respond poorly to in the past. This is because the digestive system matures and develops as the baby grows.

Probiotics are “good bacteria” which thrive in the natural flora of the stomach. They help reduce the amount of bad bacteria in the stomach, too.

If you are breastfeeding, it is likely you will have the right level of good bacteria in your breast milk. There may also be colonies of this good bacteria on your skin, around the nipples.

However, whether you’re breastfeeding or bottle feeding, probiotics may help to relieve reflux in some cases. Some studies have linked probiotics to preventing stomach problems in babies.

In trials, JAMA Pediatrics reported positive results after administering five drops of a probiotic called lactobacillus resteri. The addition of probiotics resulted in shorter episodes of crying and less spitting up (source).

Remember, the main cause of reflux is due to an immature and developing digestive system. Your baby is most likely to naturally grow out of spitting up and reflux with time. Most babies will no longer suffer from this condition after the first 12 months.

However, if your baby is constantly spitting up and not gaining weight, consult your pediatrician to check for other, more complex conditions, such as GERD.

Will Spit Ups End?

Reflux and spitting up are most common within the first year of a baby’s life. Once they are one year old, they should have outgrown the condition. Otherwise, there are likely more serious underlying issues.

In some cases, reflux or spit up may need medical intervention. For example, if a child has an allergy, reflux will not end until the problem is identified and treated.

You may see quicker results if the issue is caused by simple issues, such as feeding position or routines. With proper burping and a change in feeding schedule, your little one could find relief immediately.
