Do Infants Grow Out of Colic?

What do fussy babies and kids with ADHD have in common? The answer might surprise you—and empower you to take action.

If you’re a parent dealing with a colicky baby, you’ve probably heard these words from well-meaning healthcare providers: “Don’t worry, they’ll grow out of it.” But here’s what no one is telling you—babies don’t just grow out of colic. They grow into other challenges.

The endless crying, the back arching, the sleepless nights that leave you questioning everything you’re doing as a parent—these aren’t just difficult phases that magically disappear. They’re your baby’s way of communicating that something deeper is happening in their nervous system.

The Truth About What Happens After Colic

Every week, parents walk into healthcare offices with seven-year-olds struggling with sensory issues, ADHD, or anxiety. When practitioners dig into these children’s histories, there it is—they were colicky babies. The same stress that caused endless crying at three months old is now causing meltdowns at seven years old. The labels changed, but the underlying problem never left.

You’re not imagining the connection, and you’re certainly not failing as a parent.

Why Everything You’ve Tried Hasn’t Worked

If you’re reading this, chances are you’ve already tried everything—eliminating dairy from your diet if you’re breastfeeding, keeping detailed food journals, trying every colic drop and remedy on the market, adjusting feeding schedules, and following countless pieces of advice from family, friends, and online forums.

You’re exhausted, overwhelmed, and probably wondering what you’re doing wrong. Here’s the truth: You’re not doing anything wrong. You’re just missing the most important piece of the puzzle.

The Real Root Cause Goes Deeper Than Digestion

Most people think colic is purely a digestive issue—gas, indigestion, food sensitivities. While these symptoms are real and distressing, they’re only part of the story. The digestive system is completely controlled by the nervous system.

Think of your baby’s nervous system as their internal air traffic controller. This system coordinates every function in their tiny body. When that controller gets stressed and overwhelmed, everything starts backing up—digestion, sleep, emotional regulation, and development.

The vagus nerve, often called the “master nerve,” travels from the brainstem all the way down through the neck, controlling the esophagus, stomach, and intestines. When birth trauma or stress affects this nerve, digestion literally gets stuck.

This is why we need to change how we think about colic. Instead of seeing it as a mysterious condition your baby will “grow out of,” understand it for what it really is: STUCK.

• Baby gets stuck in the birth canal during delivery
• Stress gets stuck in their nervous system
• Digestion gets stuck
• Your baby stays stuck in distress

The Hidden Trigger No One Discusses: Birth Trauma

Here’s a pattern that’s impossible to ignore: nearly 100% of colicky babies have experienced some form of birth intervention—C-sections, forceps delivery, vacuum extraction, or labor induction. These interventions, while sometimes medically necessary, create physical stress on the upper neck area where crucial nerves originate.

But the stress often begins even before birth. The umbilical cord acts like a direct connection, transferring your stress during pregnancy to your baby’s developing nervous system. If you experienced anxiety, physical discomfort, or stress during pregnancy, your baby’s nervous system was already on high alert before they even arrived.

The physical tension from birth gets stuck in two key places: the upper neck area and the middle back. This explains why colicky babies arch their backs and stiffen their necks—they’re literally trying to stretch out the tension, just like you might do after sitting at a desk all day.

Your baby is communicating through their body language that the problem isn’t in their stomach—it’s in their spine and nervous system.

The Progression Every Parent Should Know About

Here’s the timeline that plays out for countless families when the underlying nervous system stress isn’t addressed:

• Colic (0-6 months): Crying, digestive issues, sleep problems
• Chronic ear infections (6-18 months): Repeated infections requiring antibiotics
• Speech delays (18-36 months): Late talking or unclear speech
• Sensory processing issues (3-5 years): Over-sensitivity to sounds, textures, or environments
• ADHD/anxiety (5-10 years): Difficulty focusing, emotional dysregulation

Each stage involves the same stuck stress pattern affecting your child’s nervous system—it just shows up differently as they grow and develop. The colic didn’t disappear; it transformed into new challenges.

Making matters worse, all those antibiotics prescribed for recurring ear infections can disrupt gut health, while other medications may increase nervous system stress. Now you have a child heading toward emotional and behavioral challenges, and traditional therapies may feel like pushing a car with the parking brake still on.

What Your Baby’s Body Language Is Telling You

When your baby cries inconsolably and arches their back, they’re not just expressing discomfort—they’re giving you valuable information. That back arching isn’t about gas or reflux; it’s your baby’s instinctive attempt to release tension in their nervous system.

Just as you might stretch your neck and back after a stressful day, your baby is trying to relieve the physical tension stored in their spine and nervous system from their birth experience.

Understanding that colic isn’t something you have to just “wait out” is the first step to helping your child heal and thrive. Your baby isn’t broken, defective, or unusually difficult—they’re stuck in a stress pattern that can be addressed.

The earlier you address nervous system stress, the faster children heal. This is because of neuroplasticity—the brain’s amazing ability to form new connections and patterns, especially in infancy and early childhood.

Taking Action: What Parents Can Do

• Trust your instincts. You know your baby better than anyone. If something feels off, don’t let anyone dismiss your concerns with “they’ll grow out of it.”
• Look for practitioners who understand the nervous system connection. Seek providers who look at the whole child, not just individual symptoms. Ask about their approach to addressing nervous system stress and birth trauma.
• Consider the birth experience. Reflect on your pregnancy and birth experience. Were there interventions? Stress during pregnancy? Extended labor? This information can provide valuable clues.
• Think beyond quick fixes. While symptom management has its place, focus on finding practitioners who want to address root causes rather than just managing symptoms.
• Document patterns. Keep track of when your baby is most distressed, what seems to help, and any family history of similar challenges. This information can be valuable for healthcare providers.

Your Child Deserves More Than Labels and Management

Your baby doesn’t need more labels, more medications to manage symptoms, or parents who feel helpless and exhausted. They need their nervous system to shift from a stressed, stuck state to a balanced, thriving state.

When that stuck tension from birth gets addressed properly, families often see remarkable transformations. Babies who once cried constantly become content and happy. Sleep improves. Digestion settles. The whole family dynamic can shift.
