Picture your baby's developing nervous system as a small stream, still carving its own path, easily shaped by whatever flows into it. Two different things can muddy that stream before your baby ever takes a first breath outside the womb. One comes from you, and one comes from the birth itself. Most colic conversations only mention one of the two, which is part of why so many families feel like they have tried everything and still cannot find the actual source of the crying.
What Colic Actually Looks Like
Colic means intense, inconsolable crying for more than three hours a day in a baby who is otherwise healthy, usually starting around two weeks old and peaking near six weeks. It shows up alongside clenched fists, an arched back, legs pulled up toward the belly, a red flushed face, and a hard, distended stomach that sometimes eases briefly after passing gas. This is a different category of crying than ordinary fussiness. It is a baby in real distress, and it affects roughly one in four newborns, disrupting sleep and daily life for the whole family.
The First Source: Stress Carried Over From Pregnancy
A baby's nervous system develops in direct connection with the mother's. High levels of stress, anxiety, or fear during pregnancy do not stay contained to the mother alone. They feed into the baby's developing wiring before birth even happens, priming a nervous system to run a little hotter and settle a little less easily once your baby arrives.
The Second Source: Physical Stress During Birth
The second piece comes from the birth itself. A C-section, a forceps or vacuum delivery, or simply a long and hard labor can place real physical strain on a newborn's upper neck and brainstem. That region houses the vagus nerve, the nerve responsible for the parasympathetic rest and digest functions your baby needs for feeding, sleeping, and moving gas and stool along smoothly. Tension in that area can leave the nerve unable to do its job well, even in births that looked completely uneventful from the outside, and even a routine, scheduled delivery still asks a lot of a newborn's small neck and shoulders on the way out.
Why Two Sources Are Worse Than One
It helps to think about it this way: neither a stressful pregnancy nor a hard delivery has to be dramatic to leave a mark. Plenty of parents who describe their birth as fine, quick, or textbook still end up with a colicky baby, because the strain that matters most is often mechanical and quiet rather than obviously traumatic.
Neither source alone always adds up to colic. Plenty of babies come through a stressful pregnancy or a hard delivery and settle just fine. The pattern that tends to produce colic is both landing together, prenatal stress priming the nervous system toward high alert, then birth stress adding physical tension right where the calming signals need to travel. Picture it like a dam built in the wrong place on that stream: pressure builds up behind it instead of flowing through to the organs that need direction, and crying is often the only way a baby has to signal the backup.
When that happens, your baby's nervous system tends to get stuck leaning on the gas pedal, the sympathetic fight or flight side, while the brake pedal, run largely by the vagus nerve, cannot fully engage. Digestion slows. Gas has trouble moving through. The muscle at the top of the stomach loses some of its tone, which is part of why colic, reflux, and constipation so often travel together in the same baby rather than showing up as separate issues.
Why the Usual First Tries Only Go So Far
Gas drops, gripe water, and formula changes are reasonable first steps, and they address something real about your baby's discomfort. What none of them reach is the vagus nerve signaling underneath the discomfort. That is why so many families describe short term relief that fades right back to the same crying pattern within a day or two. The two part storm behind colic is a nervous system story first, and a digestive story second.
What We Look At in the Exam Room
Every visit is built around your baby specifically. Some families notice a shift within the first one to three adjustments, occasionally sooner. Others need a bit more time as the nervous system slowly learns a new, calmer pattern. Either way, our doctors track your baby's progress closely and adjust the plan as needed rather than guessing.
Before anything else, we sit down with you and take in the whole picture: how the pregnancy went, what the birth was actually like, feeding patterns, and every remedy you have already tried at home. Then comes a gentle hands on exam paired with INSiGHT neurological scanning, which gives us a clear read on where your baby is holding tension. From there, our doctors use Koren Specific Technique and Talsky Tonal Chiropractic to reach the top of the neck, close to where the vagus nerve first branches out, plus the mid and lower back segments connected to digestion and elimination. Nothing about it is forceful. The touch is featherlight, gentler than pressing a ripe piece of fruit, and it is common for a baby to go slack or drift off partway through.
Parents most often notice changes in these areas first:
- Less crying overall, and shorter stretches when it does happen
- An easier latch and calmer feeds
- Less gas, bloating, and spit up after meals
- More regular, comfortable bowel movements
- Better sleep for the baby, which usually means better sleep for everyone else too
Where to Go From Here
If your baby's crying has not budged no matter what you have tried, it is worth looking at both halves of the storm rather than just the digestive piece everyone starts with.
