The Overlooked Signs of Acid Reflux in Children

While occasional spit-up or tummy upset is common in kids, persistent or unusual symptoms may indicate reflux. Here are some of the commonly missed signs:

  • Chronic cough or wheezing, especially at night, caused by stomach acid irritating the throat and airways.

  • Hoarseness or sore throat that occurs without a cold, possibly from acid reaching the voice box.

  • Dental problems like enamel erosion leading to cavities and sensitivity.

  • Frequent bad breath despite good oral hygiene, due to acid exposure.

  • Sleep disturbances, including night waking, discomfort lying flat, or restlessness.

  • Feeding difficulties or picky eating -children may avoid foods that cause pain.

  • Irritability or mood swings stemming from ongoing discomfort.

Because these signs overlap with everyday childhood issues, many cases of acid reflux in kids go unnoticed until symptoms become more severe.

Why Parents Often Miss the Signs

The tricky part is that many of the acid reflux symptoms overlap with everyday childhood problems. For example:

  • A cough may seem like allergies, a lingering cold, or even asthma. Because coughing is so frequent in children for these reasons, acid reflux-related throat irritation can easily be mistaken for another minor respiratory problem.
  • Dental issues such as enamel erosion, sensitivity, or increased cavities are often blamed on poor brushing habits or dietary choices. Parents may not realize that stomach acid reaching the mouth can weaken enamel and contribute to these dental problems.
  • Refusing food or picky eating is seen as typical childhood behavior or fussiness. However, in children with acid reflux, food avoidance can be a response to pain or discomfort caused by foods irritating the esophagus or stomach.

Because acid reflux doesn’t always look like “classic” heartburn in kids, parents may not connect the dots until the condition becomes more severe.

What Parents Can Do

If you suspect your child may be experiencing acid reflux, here are practical steps to take:

  • Consult a pediatrician - Share your observations; they may recommend tests or a referral to a specialist.
  • Track symptoms - Keep a diary of when issues occur (especially after meals or at night).

  • Review diet and habits - Limit acidic or spicy foods, avoid late-night meals, and encourage your child to eat smaller portions.

  • Adjust bedtime routines - Keeping the head slightly elevated during sleep can reduce nighttime reflux.

  • Follow medical advice - In some cases, a doctor may recommend medication to reduce acid and prevent further irritation.

Key takeaways

Children often don’t describe acid reflux the way adults do, e.g. they may not mention “heartburn.”

Subtle symptoms like coughs, sore throats, or disrupted sleep can be signs of acid reflux.

Tracking symptoms and consulting a pediatrician helps with early diagnosis.

Simple changes in diet, routine, and sleep position can provide relief, but medical guidance is key if symptoms persist.

Can babies and toddlers have acid reflux?

Yes. Reflux is actually quite common in infants, though it usually improves as the child grows. Persistent or severe symptoms, however, may require medical evaluation.

What foods make reflux worse in children?

Acidic foods (like citrus and tomatoes), chocolate, fried foods, and spicy meals are common triggers. Eating too close to bedtime can also worsen symptoms.

When should I see a doctor about my child’s acid reflux?

If your child has ongoing coughs, difficulty swallowing, frequent vomiting, poor growth, or disrupted sleep, it’s important to consult a pediatrician.

Can acid reflux affect my child’s teeth?

Yes. Stomach acid can erode enamel, leading to cavities and sensitivity. If your child has unexplained dental issues, reflux may be a contributing factor.
