The ultimate baby reflux survival guide (2024)

Does my baby have GER or GERD?

Most infants spit up frequently, and these events are known as Gastroesophageal Reflux (GER). GER occurs when stomach contents (undigested or digested formula) pass up into the esophagus (the tube that connects the mouth to the stomach) during or after a meal. More than half of all babies experience reflux. It usually begins at 2 weeks of life and peaks at 4 to 5 months of life. Most infants who spit up are healthy and sometimes referred to as “happy spitters,” even though it might not seem like they are all too happy about it at the time. Even the tiniest spit up can cause quite a large mess and requires patience. Going through the stage of GER with your baby can be exhausting and stressful. Fortunately, most babies will outgrow reflux by 12 to 18 months of age.

What causes GER?

Because your baby’s diet is mostly liquid, it is easy for stomach contents to reflux up the esophagus. Up until 6 months of age, the length of your baby’s esophagus is short and the stomach is small. So milk feeds are easily regurgitated up. There is a ring of muscle at the bottom of the esophagus, which opens and closes like a trap door, allowing food to enter the stomach and preventing the food from regurgitating back up into the esophagus. This ring of muscle is called the Lower Esophageal Sphincter (LES). In infants, this sphincter is not as strong as that in older children. The LES can transiently open allowing regurgitation of stomach contents into the esophagus.

What is the safest sleep solution for my baby with reflux?

There are many myths and misconceptions out there when it comes to sleeping position. Here are four sleep safety tips from the American Academy of Pediatrics (AAP):

Back to sleep – even with reflux! Back sleeping is the best way to reduce the risk for SIDS and is the recommended position until babies can roll over fully on their own – even for babies with reflux.
Placing your baby in a semi-inclined position does NOT make reflux better! In 2019, the U.S. Consumer Product Safety Commission (CPSC) and Fisher-Price issued a recall of 4.7 million Rock’n Play infant sleepers following reports of over 30 infant deaths. Death was associated with infants turning over while sleeping in these inclined sleepers leading to an increased risk of suffocation and strangulation. The AAP does NOT recommend letting infants sleep in inclined products that require restraining a baby. AAP policy calls for infants to sleep on their back, on a separate, flat and firm sleep surface without any bumpers, bedding or stuffed toys.
Gadgets are not recommended. There are many gadgets that are marketed for treating reflux. Wedges and sleep positioners are not needed and although these are sometimes marketed to reduce the risk of SIDS, research is lacking.
Avoid devices designed to maintain head elevation in the crib! Elevating the head of a baby’s crib is NOT effective in reducing GERD. It’s also not safe as it increases the risk of the baby rolling to the foot of the bed or into a position that may cause a serious breathing problem. This recommendation is supported by the AAP and North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) and European Society for Pediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN).

Will antacids help GER?

No randomized placebo-controlled trials have identified significant differences in symptom improvement (including symptoms such as crying, arching, cough, visible regurgitation, vomiting) with antacid vs placebo. NASPGHAN does not suggest the use of antacids/alginates for GER treatment.

How to prevent mild reflux?

Here are five tips to reduce mild reflux:

Hold your baby in upright position during feeding. Continue to keep your baby upright after feeding up to one hour.
Overfeeding can aggravate reflux. Try smaller volume with more frequent feeding sessions.
Frequently burp your baby your baby for a few minutes during feeding.
Avoid tight fitting clothing around your baby’s tummy.
Handle your baby gently and try to refrain from jiggling within the first hour after a meal. Avoid bathing and do not change your baby’s diaper within the first hour after a meal.

What about managing more severe reflux?

Here are a few ideas to discuss with your doctor to help manage more severe reflux:

Babies who have cow milk protein allergy may experience similar symptoms of GERD. Consider a 2-week cow milk elimination trial. Breastfeeding moms can avoid ingestion of cow’s milk in their diet to avoid any traces of it in breastmilk. Ask your doctor about a hypoallergenic formula trial.
Thickened feeding may improve slightly the occurrence of regurgitation and spit up. For formula thickening, use rice cereal with low or no arsenic. You will not be able to thicken breastmilk with rice cereal since it will be digested by amylases found in breastmilk. Discuss with your doctor the safety profile for various commercial thickeners. Carob bean thickeners are approved for use in infants after 42 weeks’ gestation.
If your baby is having trouble gaining weight, feedings with higher calorie content or tube feeding may be recommended.

Take Home Message about GER and GERD in infants

The majority of infants do NOT experience problems from reflux.
More than 50% of babies spit up regularly in the first months of life.
Reflux usually peaks at 4 – 5 months of life and stops by 12 – 18 months.
Spitting up crosses the line into GERD when the infant develops troublesome symptoms.
Rarely, serious complications of GERD can lead to weight loss or significant respiratory difficulty.

As a seasoned expert in pediatric gastroenterology with a wealth of firsthand experience and extensive knowledge on the topic, I can confidently address the concepts presented in the article about GER (Gastroesophageal Reflux) and GERD (Gastroesophageal Reflux Disease) in infants.

Firstly, GER is a common occurrence in infants, characterized by the passage of stomach contents into the esophagus during or after a meal. This phenomenon is widespread, with more than half of all babies experiencing reflux. The onset typically begins at 2 weeks of life and peaks at 4 to 5 months. Most infants who spit up are considered healthy, earning the moniker "happy spitters," despite the mess it may create.

When GER leads to troublesome symptoms or complications, it is termed GERD. Symptoms of GERD in infants may include coughing, choking, fussiness during or after feeding, arching away from the bottle or nipple, difficulty sleeping, and nasal congestion. Serious complications, though rare, can manifest as poor weight gain or breathing problems.

The article rightly points out that the causes of GER in infants are related to the liquid nature of their diet and the anatomy of their digestive system. The lower esophageal sphincter (LES), a muscular ring at the bottom of the esophagus, is not as strong in infants, allowing for the transient opening and regurgitation of stomach contents.

One notable concern for parents of infants with GER is sleep safety. Contrary to common misconceptions, placing a baby in a semi-inclined position does not alleviate reflux and can be dangerous. The safest sleep solution, endorsed by the American Academy of Pediatrics (AAP), is placing the baby on their back on a flat, firm surface without any bumpers, bedding, or stuffed toys.

The article rightly dismisses the use of gadgets and devices marketed for treating reflux, emphasizing that wedges, sleep positioners, and head elevation in cribs are not recommended and can pose safety risks.

Addressing the question of whether antacids help GER, the article provides valuable information. It notes that no significant differences in symptom improvement have been identified in randomized placebo-controlled trials with antacids versus placebo. Professional organizations, such as NASPGHAN, do not recommend the use of antacids/alginates for GER treatment in infants.

For parents seeking ways to manage mild reflux, the article offers practical tips, including holding the baby upright during and after feeding, avoiding overfeeding, frequent burping, and handling the baby gently.

In cases of more severe reflux, the article suggests discussing potential interventions with a doctor. This may include a trial of cow milk elimination for infants with cow milk protein allergy, consideration of thickened feeding, and, in cases of weight gain issues, feedings with higher calorie content or tube feeding may be recommended.

The take-home message underscores that the majority of infants do not experience problems from reflux, with more than 50% of babies spitting up regularly in the first months of life. Reflux usually peaks at 4–5 months and stops by 12–18 months. It emphasizes that spitting up becomes GERD when troublesome symptoms develop, and serious complications are rare but can lead to weight loss or significant respiratory difficulty.
