Formula for Infants with Acid Reflux

Acid reflux happens when stomach contents and acid travel back up into the esophagus and throat. The esophagus is the channel connecting the throat to the stomach.

This is a frequent issue among babies, particularly those aged 3 months or younger.

We’ve teamed up with EleCare ® to share guidance on appropriate formula choices for infants who experience acid reflux.

What is acid reflux?

Acid reflux commonly arises when the lower esophageal sphincter (LES) is weak or not fully developed. The LES is the muscle that sits between the stomach and the esophagus.

Under normal circumstances, it functions like a one-way valve that briefly opens when swallowing. If the LES fails to close correctly, stomach contents can return into the esophagus. Reflux can also stem from a hiatal hernia or from food sensitivities.

An otherwise healthy baby with mild reflux may spit up after feeds but usually won’t seem distressed. Most infants outgrow reflux by around 12 months of age. Still, in some babies, reflux can be more serious.

Symptoms of severe reflux in infants

Indicators of significant reflux in infants include:

• persistent crying and fussiness
• poor or stalled weight gain
• refusing feeds
• stools that contain blood or resemble coffee grounds
• frequent or forceful vomiting
• vomit that is yellow, green, bloody, or looks like coffee grounds
• wheezing or persistent coughing
• trouble breathing
• apnea (pauses in breathing)
• bradycardia (slow heart rate)

Severe reflux symptoms are uncommon, but if your baby shows any of the above signs, contact your pediatrician right away. These symptoms could signal a critical condition that needs immediate attention.

Treatment

How reflux is treated in infants depends on how severe it is.

In many instances, your doctor will suggest modifying feeding techniques. Occasionally, they might advise making changes to the baby’s formula.

Do not alter your baby’s formula or stop breastfeeding without consulting your physician.

Mild acid reflux

For mild, recurring reflux, a doctor may suggest mixing one to two teaspoons of rice cereal into formula. Thickening the formula can make stomach contents heavier and less likely to be regurgitated.

Keep in mind this can reduce vomiting frequency but doesn’t eliminate reflux entirely.

Also, adding cereal to an infant’s bottle before about 4 months of age can increase the risk of allergic reactions or other problems like overfeeding or choking. Only add cereal if your pediatrician has recommended it.

Severe acid reflux

If reflux is severe, your doctor might recommend changing the type of formula.

Most standard infant formulas are based on cow’s milk and enriched with iron. Some babies react to a protein in cow’s milk, which can exacerbate reflux, making it necessary to switch to a different formula type.

Best formulas for severe acid reflux

Hydrolyzed Protein Formulas

Hydrolyzed protein formulas originate from cow’s milk but have proteins broken down into smaller components to aid digestion. These formulas are often the most helpful at reducing reflux and are commonly suggested when a food allergy is suspected.

Your pediatrician may recommend trying a hydrolyzed formula for a few weeks if they suspect an allergy. These options typically cost more than standard formulas.

Soy Milk Formulas

Soy-based formulas contain no cow’s milk proteins. They’re generally suggested for babies with lactose intolerance or galactosemia. Lactose intolerance is the inability to digest lactose, a type of sugar, while galactosemia is a genetic condition that prevents proper breakdown of galactose.

Both lactose and galactose are present in cow’s milk. Soy formulas are not usually advised for premature infants since they may influence bone growth.

There are also questions about possible hormonal or immune impacts from soy-based options. Soy formulas tend to be pricier than cow’s milk–based formulas.

Specialized Formulas

Specialized formulas are formulated for infants with specific medical conditions or needs, such as prematurity. Consult your pediatrician to determine which specialized formula is appropriate for a baby with particular health concerns.

EleCare ® is a complete, specialized amino acid–based formula intended for dietary management of food allergies and gastrointestinal disorders. It is hypoallergenic and commonly recommended by healthcare providers for both infants and children.

Other tips

Keep the following practical tips in mind while feeding your baby, no matter the root cause of reflux:

• Burp your infant more frequently (often after every one to two ounces of formula).
• Avoid feeding too much at once.
• Offer smaller feedings more often.
• Hold your baby upright for 20 to 30 minutes after a feed.
• Don’t bounce or jostle your baby after feeding; this can prompt stomach contents to return upward.
• Wait about 30 minutes after feeding before laying your baby down to sleep.
• Try different nipple sizes or bottle types when bottle-feeding to see what reduces reflux.

Additionally, if you’re researching infant sleep positions in relation to reflux, see resources on baby sleeping on side for more context and safety guidance.

Bottom line

While acid reflux can make your baby uncomfortable, it is manageable. Adjusting feeding practices and switching formulas can help control reflux. If your infant has severe symptoms or doesn’t improve with feeding changes, speak with your doctor about medications or additional treatments.
