It's the middle of the night again, and the cry coming from the crib is different from a hungry cry or a wet-diaper cry. You've fed, burped, changed, and rocked, and none of it is landing. Their fists are balled up tight. Their legs keep drawing toward their belly. Their back keeps arching away from you no matter how you hold them. You're standing in a dark room trying to figure out if this is just a hard night, or something with an actual name.
Here is a specific list to check your baby against, rather than guessing in the dark.
The Signs Worth Checking Tonight
Colic has an actual clinical shape to it, not just a vague label for a fussy baby. The signs that point toward colic rather than ordinary fussiness include:
- Crying spells lasting more than 3 hours a day, more than 3 days a week, for more than 3 weeks
- High-pitched, distressed screaming that sounds different from a typical cry
- Crying that doesn't ease with feeding, a diaper change, or the usual soothing tricks
- A predictable pattern, often hitting hardest in the late afternoon or evening
- Facial grimacing and a flushed or reddened face during the worst stretches
- Stiff, tense arms and legs, clenched fists and curled toes while crying
- Repeated arching of the back, as if trying to pull away from discomfort
If several of these sound familiar, especially the back arching and the clenched fists together with a predictable evening pattern, you are very likely looking at colic rather than a run of unusually fussy nights. It's also worth knowing that colic is genuinely common. Roughly a quarter of babies show this pattern in the first weeks of life, so if tonight looks like this, you are far from the only parent standing in a dark room wondering what's going on.
Why It Isn't Just Gas
Gas drops and gripe water treat one possible piece of this picture, and sometimes they help a little. But gas alone doesn't explain why a baby's back arches, why their face grimaces mid-cry, or why the crying shows up at almost the same time every evening like clockwork. Something more coordinated is going on than a simple bubble of trapped air. It's also worth setting aside the idea that colic is simply something to wait out. The stretch it covers, even if it eventually eases on its own, still means real weeks of lost sleep, feeding struggles, and strain on bonding for the whole family, which is reason enough to look closer at what's actually driving it rather than treating the clock as the only plan.
What's Actually Happening in the Nervous System
The vagus nerve runs from the brainstem down through the neck and into the abdomen, and it's the main communication line between the brain and the digestive system. When that line is working well, digestion moves smoothly and the "rest and digest" side of the nervous system can do its job. When tension builds along that pathway, often from the physical strain of birth itself, whether that was a long labor, a vacuum or forceps delivery, or a C-section, the signal gets disrupted.
That disruption shows up as exactly the signs on the checklist above: tensed muscles, an arching back, a racing heart with nothing external to explain it, and an overwhelming urge to cry that won't settle with the usual comforts. The crying isn't random. It's a nervous system stuck in an alert, uncomfortable state, trying to signal that something needs attention.
Why the Signs Cluster Together
Maternal stress during pregnancy, the physical demands of labor and delivery, and early exposure to antibiotics or infections can each add strain to a very young, still-developing nervous system. Stacked together, these factors can leave a baby's vagus nerve signaling out of sync before they've even had a chance to settle into life outside the womb. That's part of why colic so often shows up alongside reflux or constipation in the same baby. Different symptoms, same underlying signal.
Our Approach
We start by hearing your baby's birth story, feeding pattern, and the specific timing of the crying spells you've noticed. From there, a gentle exam and INSiGHT neurological scanning, when appropriate for your baby's age, show us where nervous system stress is being held. Using Koren Specific Technique and Talsky Tonal Chiropractic, our doctors work with light, nervous system focused adjustments, pressure far gentler than what you'd use to check a piece of fruit, targeting the upper neck where the vagus nerve begins its path toward the digestive organs.
Many parents describe less crying, easier feeding, and a calmer evening stretch within the first few visits. Sleep for the whole family tends to improve once your baby is settling more easily, and the predictable evening pattern often becomes noticeably shorter or quieter as care continues.
What to Watch For Between Now and Your Visit
- Note the time crying spikes each day. A consistent pattern is useful information, not just an exhausting coincidence.
- Prop your baby upright for a stretch after each feed so trapped air has an easier path out.
- Watch specifically for the back arching and clenched fists together. That combination is one of the clearer colic signals.
- Keep track of bowel movements alongside the crying pattern. The two often shift together as things improve.
Where to Go From Here
If tonight lined up with what's on this list, our doctors in Royal Oak would be glad to take a look and walk you through what they find.
