Are you experiencing frequent spit-ups, irritability, and disturbed sleep in your baby? If so, you're not alone. Gastroesophageal reflux (GER), commonly known as reflux, is a condition that affects many infants and toddlers. It occurs when stomach contents flow back into the esophagus, causing discomfort and sometimes pain.
While reflux is common in infants, it tends to peak around 4 months of age. This is because the muscles that control the valve between the stomach and esophagus are still developing and immature. As a result, the valve may not close properly, allowing stomach contents to flow back up into the esophagus. Additionally, babies' stomachs are smaller and hold less food, which can also contribute to reflux.

Why Does Reflux Peak at 4 Months?
Here are 8 important points to consider:
- Immature valve
- Smaller stomach
- Increased milk intake
- Lying down position
- Solid food introduction
- Certain medical conditions
- Delayed stomach emptying
- Weak abdominal muscles
These factors can all contribute to the peak in reflux symptoms at around 4 months of age.
Immature valve
The valve that controls the passage of food from the esophagus to the stomach is called the lower esophageal sphincter (LES). In infants, the LES is still developing and immature. This means that it may not close properly, allowing stomach contents to flow back into the esophagus.
- Weak LES: The LES muscle in infants is weak and underdeveloped, making it more likely to relax and allow reflux to occur.
- Increased abdominal pressure: Activities such as crying, coughing, and straining can increase abdominal pressure, pushing stomach contents up into the esophagus.
- Lying down position: When babies lie down, gravity can pull stomach contents back up into the esophagus, especially if the LES is weak.
- Delayed stomach emptying: In some infants, the stomach takes longer to empty its contents, which can lead to increased reflux.
As babies grow and develop, the LES typically matures and strengthens, and reflux symptoms usually improve by the time they are 1 year old.
Smaller stomach
Babies' stomachs are much smaller than adults' stomachs, holding only a few ounces of milk or formula at a time. This means that babies need to eat frequently, and their stomachs are often full or overfull.
- Frequent feedings: Babies need to eat every 2-3 hours, which means their stomachs are often full or overfull.
- Overfeeding: Overfeeding can stretch the stomach and make it more likely for stomach contents to reflux into the esophagus.
- Rapid feeding: Rapid feeding can also lead to overfeeding and reflux. It is important to pace feedings and allow babies to take frequent breaks.
- Lying down after feeding: Laying babies down immediately after feeding can increase the risk of reflux, as gravity can pull stomach contents back up into the esophagus.
As babies grow and their stomachs get bigger, they are able to eat larger volumes of milk or formula less frequently, which can help to reduce reflux.
Increased milk intake
As babies grow and develop, their milk intake increases significantly. This is especially true during the first 4 months of life, when babies' stomachs are still small and they need to eat frequently. Increased milk intake can contribute to reflux in several ways:
Overfeeding: If babies are fed too much milk or formula at once, their stomachs may become overfull and more likely to reflux. Overfeeding can also stretch the stomach and weaken the LES, making it more likely for stomach contents to flow back into the esophagus.
Rapid feeding: Rapid feeding can also lead to overfeeding and reflux. When babies drink milk or formula too quickly, they may not have time to properly digest it, which can increase the risk of reflux.
Lying down after feeding: Laying babies down immediately after feeding can increase the risk of reflux, as gravity can pull stomach contents back up into the esophagus. This is especially true if babies are placed on their backs, as this position can put pressure on the stomach and make it more likely for milk to reflux.
To reduce the risk of reflux related to increased milk intake, it is important to avoid overfeeding, pace feedings, and keep babies upright for at least 30 minutes after feeding.
In addition to the above, some babies may also experience reflux if they have a milk allergy or intolerance. If you suspect that your baby may have a milk allergy or intolerance, talk to your doctor.
Lying down position
When babies lie down, gravity can pull stomach contents back up into the esophagus, especially if the LES is weak. This is why reflux is often worse at night and after feedings, when babies are typically lying down.
- Sleeping on the back: Babies are typically placed on their backs to sleep, as this position is considered to be the safest. However, sleeping on the back can increase the risk of reflux, as it allows stomach contents to flow more easily into the esophagus.
- Elevated head position: Elevating the baby's head and shoulders during sleep can help to reduce reflux. This can be done by using a wedge pillow or by placing a rolled-up towel under the baby's mattress.
- Side sleeping: Some babies may also benefit from sleeping on their side. This position can help to keep stomach contents from flowing back into the esophagus.
- Avoid lying down after feeding: It is best to keep babies upright for at least 30 minutes after feeding to allow their stomachs to empty and reduce the risk of reflux.
If your baby has reflux, it is important to talk to your doctor about the best sleeping position for your baby.
Solid food introduction
Around 4-6 months of age, babies typically start eating solid foods. The introduction of solid foods can affect reflux in several ways:
- Increased stomach acid: Solid foods can increase the production of stomach acid, which can irritate the esophagus and worsen reflux symptoms.
- Delayed stomach emptying: Some solid foods, such as fatty or high-protein foods, can take longer to digest, which can delay stomach emptying and increase the risk of reflux.
- Food allergies or intolerances: Some babies may have food allergies or intolerances, which can trigger reflux symptoms. Common allergenic foods include milk, eggs, wheat, and soy.
- Overfeeding: It is important to avoid overfeeding babies when they start eating solid foods. Overfeeding can stretch the stomach and make it more likely for stomach contents to reflux.
To reduce the risk of reflux related to solid food introduction, it is important to start with small amounts of food and gradually increase the amount as your baby gets used to it. It is also important to avoid giving your baby foods that are high in fat or protein, or that you suspect your baby may be allergic to.
Certain medical conditions
In some cases, reflux can be caused or worsened by underlying medical conditions. These conditions can affect the function of the LES or the stomach, making it more likely for stomach contents to reflux into the esophagus.
Some medical conditions that can contribute to reflux in infants include:
- Hiatal hernia: A hiatal hernia occurs when part of the stomach pushes up through an opening in the diaphragm. This can weaken the LES and make it more likely for stomach contents to reflux.
- Pyloric stenosis: Pyloric stenosis is a condition in which the pyloric valve, which controls the flow of food from the stomach to the small intestine, is narrowed or blocked. This can cause food to back up into the esophagus.
- Eosinophilic esophagitis (EoE): EoE is a chronic condition in which the esophagus becomes inflamed due to an allergic reaction to certain foods. This inflammation can damage the esophagus and make it more susceptible to reflux.
- Cow's milk allergy (CMA): CMA is an allergy to the proteins found in cow's milk. CMA can cause inflammation and irritation of the digestive tract, which can lead to reflux.
If you suspect that your baby's reflux may be caused by an underlying medical condition, it is important to talk to your doctor. Early diagnosis and treatment of the underlying condition can help to improve reflux symptoms.
In most cases, reflux in infants is a temporary condition that will improve as the baby grows and develops. However, if your baby's reflux is severe or does not improve with home treatment, it is important to talk to your doctor.
Delayed stomach emptying
Delayed stomach emptying, also known as gastroparesis, is a condition in which the stomach takes longer than normal to empty its contents into the small intestine. This can lead to a buildup of food and stomach acid in the stomach, which can increase the risk of reflux.
- Immature digestive system: In infants, the digestive system is still developing and maturing. This means that it may take longer for food to move through the stomach and into the small intestine.
- Certain medical conditions: Some medical conditions, such as pyloric stenosis and Hirschsprung's disease, can cause delayed stomach emptying.
- Medications: Some medications, such as opioids and antidepressants, can slow down stomach emptying.
- Feeding practices: Overfeeding and rapid feeding can both contribute to delayed stomach emptying.
If you suspect that your baby may have delayed stomach emptying, it is important to talk to your doctor. Treatment for delayed stomach emptying may include dietary changes, medications, or surgery.
Weak abdominal muscles
Weak abdominal muscles can also contribute to reflux in infants. The abdominal muscles help to support the stomach and keep it in place. When the abdominal muscles are weak, the stomach may be more likely to move out of place and allow stomach contents to reflux into the esophagus.
- Premature birth: Premature babies often have weaker abdominal muscles than full-term babies.
- Low muscle tone: Some babies may have low muscle tone, which can affect the strength of their abdominal muscles.
- Lack of tummy time: Tummy time is important for strengthening the abdominal muscles. Babies who do not get enough tummy time may have weaker abdominal muscles.
Encouraging your baby to spend time on their tummy can help to strengthen their abdominal muscles and reduce the risk of reflux. You can start tummy time when your baby is a few weeks old. Start with short sessions, such as 1-2 minutes, and gradually increase the duration as your baby gets stronger.
