When Baby is Fussy — and What Feeding Therapy Can Do About It

Here's something I tell almost every family I work with: your baby isn't being difficult. They're communicating.

And more often than not, what they're communicating is I don't feel okay right now.

When a baby is struggling to feed — arching, crying, refusing the breast, or just seeming frantic and unsettled — our instinct is to go straight to the feeding problem. The latch. The bottle. The weight gain. But what I've learned after years of working with babies and families is this: before we can work on feeding, we have to help your baby feel safe.

A calm nervous system is always where we start.

What Does "Calm Enough to Eat" Actually Look Like?

Babies can't calm themselves down or regulate their nervous system yet. They don't have that ability. They completely depend on you to help them find calm — and that calm isn't just about comfort. It's the foundation for everything.

When your baby feels safe and settled, their whole body can do what it's supposed to do. They are more likely to be able to coordinate the suck, swallow, and breathe rhythm that feeding requires. They can move their body, engage with you, and participate in play activities that we work on together to build feeding skills.

When they're not okay? A baby in distress is in survival mode — and you can't learn, play, or feed well from survival mode.

So Why Might Your Baby Be Struggling to Settle?

This is the part I love most about this work — being a detective with families, peeling back the layers to figure out what's really going on. Because it's rarely just about temperament.

Here are some of the most common reasons I see babies struggling:

Their tummy doesn't feel good. Reflux, gas, irregular bowel movements, food sensitivities — these are incredibly common, and they can make your baby uncomfortable. A baby who has learned that eating hurts is going to protect themselves. They arch. They cry. They refuse.

Feeding is taking more effort than it should. Feeding is actually one of the hardest things a human body does — it takes five sets of nerves, over 50 muscles, and multiple systems all working together. When something is off — whether that's a tongue tie, muscle weakness, tightness, a coordination issue — every single feed can be exhausting. And an exhausted baby is an unsettled baby.

The world feels like a lot. Some babies are just more sensitive than others. Bright lights, loud sounds, movement, poor sleep — it adds up fast. These babies aren't being dramatic. Their nervous systems are working overtime, and they need extra support to find their calm.

Their body is holding tension. This one surprises a lot of families. Babies can carry physical tightness — often in their neck, jaw, or shoulders — from a difficult delivery, a fast birth, a C-section, or just from the way they were positioned in the womb. That tension makes it hard to latch comfortably, turn their head, or settle into a feed. When I see this, I use gentle bodywork techniques, like craniosacral therapy and myofascial release to help the body let go.

How they came into the world. Birth matters. A long labor, a quick delivery, forceps or vacuum, a premature arrival — these experiences can leave a mark on a baby's nervous system and their body. Babies born early are suddenly in a world their nervous systems weren't quite ready for yet. They often need more time, more gentleness, and more intentional support to feel settled.

We're Always Looking for the "Why"

Co-regulation — helping your baby find calm — is always our starting point. But at the same time, I'm always working with your family to understand why your baby is struggling in the first place.

That might mean looping in your pediatrician about reflux, or referring out to a pediatric chiropractor. It might mean looking at your diet if you're breastfeeding, or adjusting how we approach feeds at home. I think of every baby as a tiny onion — and feeding therapy is the process of gently peeling back the layers, one at a time.

Breastfeeding and feeding challenges are almost never just a "mouth problem." They're a whole-baby, whole-family thing.

The Most Important Thing I'll Tell You

You are your baby's most powerful tool. When you're calm, your baby's nervous system takes notice. Your heartbeat, your voice, your warmth — all of it tells your baby you are safe. You can settle. You can eat.

Before a feed, or before any therapy activities at home, take a few minutes of just be together. Rock them. Hum. Hold them skin-to-skin. It sounds simple — but it's genuinely part of the work of helping them feed well.

If This Sounds Like Your Baby

You don't have to keep guessing. If feeding feels hard, if your baby seems unsettled, if you've tried everything and something still feels off — that's exactly what I'm here for. I always meet families where they are.
