Reflux in babies and children: What’s normal and when to worry

Babies are especially prone to reflux because the muscle that keeps stomach contents from flowing backward is still developing. They also spend much of their time lying down and drink a liquid diet, which makes spit-up more likely.

Spit-up is practically a rite of passage for new parents. One minute, your baby finishes a feeding. The next, some of that milk ends up on your shoulder. While it can be messy and sometimes concerning, reflux is a normal part of infancy.

But how can parents tell the difference between everyday spit-up and something that needs medical attention?

Dr. Shivani Gupta, a pediatric gastroenterologist at Akron Children’s, explains what reflux looks like at different ages, ways to manage symptoms at home and when to talk to your child’s doctor.

Why is reflux so common in babies?

Gastroesophageal reflux (GER) happens when stomach contents flow back into the esophagus, the tube that carries food from the mouth to the stomach.

Babies are especially prone to reflux because the muscle that keeps stomach contents from flowing backward is still developing. They also spend much of their time lying down and drink a liquid diet, which makes spit-up more likely.

Fortunately, most babies outgrow it.

“It typically peaks around 4 months of age and improves as infants mature, sit and stand more, eat solid foods and develop better gastrointestinal motility,” said Dr. Gupta.

However, there’s a difference between normal reflux and gastroesophageal reflux disease (GERD). GERD occurs when reflux causes troublesome symptoms or complications, such as feeding problems or poor growth.

Reflux typically peaks around 4 months of age and improves as infants mature, sit and stand more, eat solid foods and develop better gastrointestinal motility.

How much spit-up is too much?

According to Dr. Gupta, the amount of spit-up matters less than how your baby is doing overall.

If your baby spits up frequently but seems comfortable, feeds well, gains weight and meets developmental milestones, there’s usually little reason to worry.

Common signs of infant reflux include:

• Frequent spit-up or milk coming back into the mouth.
• Hiccups, burping or wet burps.
• Fussiness or squirming during feeds.
• Arching the back during feeding.
• Occasional coughing or gagging with feeds.

However, these symptoms don’t always mean reflux is the cause. Crying, poor sleep and irritability can have many explanations.

As children grow, their reflux symptoms may change. Older children can also describe what they’re feeling more clearly.

What does reflux look like in older children?

As children grow, their reflux symptoms may change. Older children can also describe what they’re feeling more clearly.

Toddlers and preschoolers may refuse food, gag during meals, complain of tummy aches or describe food coming back into their mouths.

School-age children may experience heartburn, a sour taste, upper belly discomfort or symptoms that worsen after eating or lying down.

Teens often experience symptoms similar to adults, including heartburn and regurgitation.

Still, not every stomachache or episode of nausea points to reflux. Other digestive conditions can cause similar symptoms.

What can parents do to help reduce reflux?

For babies with uncomplicated reflux, simple changes to feeding routines are often the best place to start.

Dr. Gupta recommends trying these strategies:

• Offer smaller, more frequent feedings when appropriate.
• Avoid overfeeding.
• Burp your baby during and after feedings.
• Keep your baby upright while awake and supervised for a period after eating.
• Avoid tight clothing or pressure around the belly after feeds.
• If bottle-feeding, make sure the nipple flow isn’t too fast.

A note about safe sleep: Even if your baby has reflux, always place them flat on their back on a firm, safe sleep surface. Never elevate the crib mattress or use wedges or sleep positioners to manage reflux. These can increase the risk of suffocation.

Can certain foods make reflux worse?

For older children and teens, eating habits may play a role in reflux symptoms.

“There isn’t a universal ‘GERD diet’ for children. Dietary triggers vary considerably from one child to another,” said Dr. Gupta.

Some common triggers include chocolate, spicy foods, tomato products, citrus, carbonated drinks, caffeine and large or high-fat meals.

However, parents don’t need to eliminate all these foods. Instead, pay attention to which foods seem to cause symptoms and make changes as needed.

Other helpful habits include eating smaller meals, avoiding lying down right after eating and allowing several hours between a large evening meal and bedtime.

Teens who experience reflux may also benefit from cutting back on caffeine and energy drinks.

When should parents be concerned about reflux?

While most infant reflux improves with time, some symptoms deserve a closer look.

Contact your child’s pediatrician if reflux is persistent or accompanied by:

• Poor weight gain or weight loss.
• Feeding refusal or significant difficulty eating.
• Ongoing pain or irritability during meals.
• Frequent coughing, gagging or choking.
• Difficulty or pain when swallowing.
• Persistent vomiting.
• Symptoms that worsen or interfere with daily activities.

Seek urgent medical care if your child has green vomit, significant blood in their vomit, a severely swollen belly, serious breathing problems, unusual lethargy or appears acutely ill. Forceful, projectile vomiting in a young infant also needs prompt medical evaluation.

These symptoms aren’t typical of uncomplicated reflux and may signal another condition.

Treatment usually starts with feeding adjustments. In some cases, a doctor may recommend thickened feeds or consider whether a cow’s-milk protein allergy is contributing to symptoms.

How is reflux diagnosed and treated?

In most cases, your child’s pediatrician can assess reflux by reviewing symptoms, feeding habits, growth and overall health. Babies with normal spit-up generally don’t need special testing.

Treatment usually starts with feeding adjustments. In some cases, a doctor may recommend thickened feeds or consider whether a cow’s-milk protein allergy is contributing to symptoms.

Medication isn’t usually necessary for otherwise healthy babies.

“Acid suppression does not stop the physical act of reflux and has potential adverse effects,” said Dr. Gupta.

For older children with ongoing heartburn or regurgitation, a doctor may recommend a short trial of acid-reducing medication. If symptoms continue, return after treatment or raise other concerns, further testing or a referral to a pediatric gastroenterologist may be needed.

The bottom line for parents

Spit-up may mean more laundry, but it doesn’t always mean something is wrong. Most babies with reflux are healthy, comfortable and growing well.

However, if reflux affects your child’s feeding, growth or daily activities, talk with your pediatrician. Together, you can determine whether simple changes at home are enough or if your child needs further evaluation.
