Why Does My Baby Have Reflux? A Gentle Guide for Concerned Parents
Share
If your baby is frequently spitting up after feedings or seems unusually fussy, you’re not alone — many new parents ask themselves, “Why does my baby have reflux?”
Infant reflux is common and, in most cases, completely normal. In this article, we’ll explore what causes reflux in babies, signs to watch for, and how to ease your baby’s discomfort, all while keeping your peace of mind intact.
👶 What Is Infant Reflux?
Infant reflux, also known as gastroesophageal reflux (GER), occurs when milk or food comes back up from the baby’s stomach into their esophagus. This happens because a baby’s lower esophageal sphincter (LES) — the muscle that keeps stomach contents down — is still developing and not yet strong enough to stay fully closed after feedings.
Reflux is very common during the first few months of life and usually peaks around 4 months of age, improving as your baby grows and their digestive system matures.
🍼 Common Causes of Baby Reflux
Here are the main reasons why your baby may have reflux:
1. Immature Digestive System
Newborns have underdeveloped muscles in their digestive tract, which makes it easier for stomach contents to flow back up.
2. Lying Down After Feeding
Babies spend most of their time lying down, which can contribute to milk flowing back into the esophagus after feeding.
3. Overfeeding
Feeding your baby too much or too quickly can overwhelm their tiny stomach, leading to spit-up or reflux.
4. Swallowing Air
Babies often swallow air during feeding, especially when bottle-fed or when latching improperly. This can increase pressure in the stomach and lead to reflux.
5. Food Sensitivities
Some babies may be sensitive to certain ingredients in formula or to foods in mom’s diet if breastfeeding (like dairy, soy, or caffeine), which can aggravate reflux symptoms.
🚨 Signs Your Baby May Have Reflux
While occasional spitting up is normal, here are some common signs of reflux to watch for:
-
Frequent spit-up or vomiting
-
Fussiness or crying during or after feedings
-
Arching of the back or neck
-
Refusal to eat or difficulty feeding
-
Wet burps or hiccups
-
Poor weight gain (in more severe cases)
🛌 Is It GER or GERD?
Most babies have mild GER and outgrow it by 12 months. However, if reflux causes serious discomfort, poor weight gain, or breathing issues, it may be gastroesophageal reflux disease (GERD) — a more serious form that requires medical evaluation.
Consult your pediatrician if you suspect GERD or if symptoms are persistent and troubling.
❤️ How to Help Your Baby with Reflux
Here are gentle, effective ways to reduce reflux and soothe your baby:
✅ Keep Baby Upright After Feedings
Hold your baby upright for 20–30 minutes after feeding to help gravity keep milk in the stomach.
✅ Burp Frequently
Burp your baby during and after feedings to release air and reduce stomach pressure.
✅ Try Smaller, More Frequent Feedings
Giving less milk more often can help prevent the stomach from becoming too full.
✅ Check Bottle & Nipple Flow
If bottle-feeding, make sure the nipple flow isn’t too fast, and try anti-colic bottles that reduce air swallowing.
✅ Consider Breastfeeding Positioning
If breastfeeding, try feeding your baby in a more upright position and ensure a good latch.
🩺 When to See a Doctor
Always speak to your pediatrician if:
-
Your baby is not gaining weight
-
Spit-up is green, yellow, or bloody
-
Your baby shows signs of pain or discomfort
-
You’re concerned about symptoms or feedings
🧘 Final Thoughts: Reflux Is Normal — and Temporary
Most cases of infant reflux are a normal part of development and improve with time. While it can be stressful for parents, it’s reassuring to know that you’re not doing anything wrong and that simple changes can make a big difference.
If in doubt, don’t hesitate to reach out to your pediatrician — trusting your instincts is part of what makes you a great parent. 💕
