Understanding Infant Reflux: What Every Mom and Caregiver Should Know About the Vagus Nerve

Bringing a new baby into your life is full of precious moments—and sometimes, a few worries, too. One thing many parents notice is that their little one spits up, vomits, or seems uncomfortable after feeding. While reflux is common in babies, did you know that the way your baby was delivered might play a role, especially after a C-section?

What’s Really Going On With Reflux?

Reflux happens when milk comes back up from your baby’s tummy, leading to spitting up or vomiting. It can be stressful to see your baby so uncomfortable, but you’re not alone—many parents face this!

A Gentle Look at the Vagus Nerve

Let’s talk about a special nerve in your baby’s body: the vagus nerve. This nerve is like a messenger, helping the brain and tummy talk to each other. It helps with digestion and keeps things calm—think of it as your baby’s “rest and digest” switch.

Why the Neck Matters—Especially After a C-Section

During some C-section births, doctors gently lift the baby out of the womb, and sometimes this means a bit of pressure around the neck. There’s a tiny bone at the top of the neck called the C1 vertebra (you can think of it like a little ring that supports the head). If this area gets tight or out of place—even a little—it can make the muscles around the neck tense up.

Why does this matter? That special vagus nerve passes right by the C1 bone. If the area is tight or compressed, the nerve can get a little “mixed up,” sending signals that keep your baby’s tummy unsettled. This can make them spit up more or seem uncomfortable after eating.

What Might You Notice?

Lots of spitting up or vomiting

Fussiness or discomfort during feeding

Trouble turning their head or seeming stiff

Arching their back while feeding

What Can You Do?

First and most importantly: don’t blame yourself. None of this is your fault, and you’re doing an amazing job! If you’re concerned about your baby’s reflux or if things don’t seem right, the very best first step is to check in with your GP or paediatrician. They can help rule out anything medical and give you peace of mind.

If your doctor gives the go-ahead and you’re looking for gentle, supportive therapies, this is where my passion comes in! As a qualified FDM (Fascial Distortion Model) therapist and baby visceral therapist, I work hands-on with infants and young children to help release tension, especially in the neck and digestive areas, in a way that is safe and comfortable for little bodies.

FDM (Fascial Distortion Model) Therapy: Using gentle, skilled touch, I help address any restrictions in the fascia (the connective tissue that runs throughout the body). Many parents tell me they see improvements in their baby’s comfort, feeding, and digestion after a session or two.

Baby Visceral Therapy: This approach focuses on gently supporting the organs and soft tissues, particularly around the tummy and digestive system. It’s all about encouraging your baby’s natural ability to find comfort and balance.

I believe every baby is unique and deserves a caring, individualized approach. My practice is dedicated to working alongside families to help babies feel their very best, especially if there’s been a challenging birth or ongoing reflux.

You’re Not Alone

It’s natural to have questions and worries as a new parent. Always trust your instincts, and know that reaching out for help is a sign of strength. If you’d like to find out more about how FDM or visceral therapy might help your little one, feel free to contact me—I’m always happy to have a friendly chat and answer any questions.
