Baby Reflux / GERD
The short answer
Gastroesophageal reflux is very common in babies because the valve at the top of the stomach is still maturing. Most infant reflux is uncomplicated, meaning your baby spits up but is otherwise happy and growing well. True GERD, where reflux causes pain, feeding difficulties, or poor weight gain, affects a smaller number of babies and is very treatable.
By Age
What to expect by age
Reflux typically begins in the first few weeks of life as feeding volumes increase. Newborns have short esophaguses and immature digestive systems, making reflux almost universal to some degree. Keeping your baby upright after feeds, offering smaller more frequent feeds, and gentle burping can significantly help. Silent reflux, where the stomach contents come up but are swallowed back down causing discomfort without visible spit-up, can be harder to spot.
Reflux often peaks around 4 months and may seem to worsen before it gets better. If your baby is consistently uncomfortable during or after feeds, arches their back, or has feeding aversions developing, talk to your pediatrician. Positional strategies and sometimes thickening feeds can help. Most pediatricians prefer to try lifestyle changes before medication.
As babies learn to sit upright and begin eating solid foods, reflux often starts to improve naturally. Gravity and thicker food consistency both help keep stomach contents down. If reflux is worsening rather than improving after 6 months, your pediatrician may want to investigate further.
The vast majority of babies outgrow reflux by 12 to 18 months as the esophageal sphincter matures. If your baby was on reflux medication, your doctor will likely try weaning off it around this time. Persistent severe reflux beyond 18 months may warrant referral to a pediatric gastroenterologist.
What Should You Do?
When to take action
- Your baby spits up but is gaining weight well and seems happy between feeds
- Reflux episodes happen after feeds and your baby settles within a few minutes
- Your baby has brief episodes of arching or fussiness after large feeds but is otherwise content
- Symptoms gradually improve after 4 to 6 months of age
- Your baby consistently cries or arches during or right after feeds, suggesting pain rather than simple spit-up
- Your baby is developing feeding aversion, turning away from the bottle or breast before finishing
- Your baby has persistent coughing, wheezing, or hoarse voice that may be related to reflux
- Weight gain is slower than expected despite adequate feeding opportunities
- Your baby is refusing to eat entirely and showing signs of dehydration such as fewer wet diapers or sunken fontanelle
- Vomit is green or bile-stained, which could indicate an intestinal obstruction
- There is blood in spit-up or vomit, or your baby is having difficulty breathing during reflux episodes

Related Feeding Concerns
I'm Worried My Baby Is Aspirating During Feeds
Aspiration means liquid or food enters the airway instead of the stomach. Occasional coughing during feeds is common and does not usually indicate aspiration. True aspiration is less common and may present as recurrent respiratory infections, a wet or gurgly voice after feeds, or chronic cough. If you are concerned, a swallow study can provide a definitive answer.
Baby Biting Nipple While Nursing
Biting during breastfeeding is a common challenge, especially when babies start teething. It can be startling and painful, but it is almost always a phase that can be managed. Babies cannot actively nurse and bite at the same time because their tongue covers the lower teeth during proper sucking. Biting typically happens at the beginning or end of a feed when the latch is not active. With some gentle strategies, most babies learn quickly that biting ends the feeding session.
My Baby Keeps Choking on Food
First, it's important to distinguish between gagging and choking. Gagging is a normal protective reflex that helps babies learn to eat, while true choking is silent and requires immediate intervention. Most "choking" episodes parents describe are actually gagging, which is common and expected as babies explore new textures. However, if your baby frequently struggles with swallowing or shows signs of true choking, it's worth discussing with your pediatrician.
My Baby Coughs While Feeding
Occasional coughing during feeding is very common, especially in newborns who are still learning to coordinate sucking, swallowing, and breathing. It often happens with a fast milk flow or letdown. However, if your baby coughs with every feed or turns blue or has difficulty breathing, this needs medical evaluation to rule out swallowing difficulties.
Baby Falling Asleep While Nursing
It is very common for babies to fall asleep while nursing, especially in the newborn period. Breastfeeding releases hormones that make both you and your baby feel relaxed and sleepy. In most cases this is completely normal, but if your baby is not gaining weight well or consistently falls asleep within a minute or two of latching, it may be worth trying some gentle techniques to keep them feeding longer.
Baby Gagging on New Textures
Gagging on new textures is one of the most common parts of learning to eat and is a normal, protective reflex. It does not mean your baby is choking or that they cannot handle the texture. The gag reflex is positioned far forward on the tongue in young babies, which means they gag more easily. With consistent, gentle exposure, most babies gradually learn to manage new textures. Going at your baby's pace while continuing to offer varied textures is the best approach.
