Do Babies Grow Out of Colic?

If your baby cries endlessly, arches their back, or struggles to sleep, you’ve likely been told, “Don’t worry—they’ll grow out of it.” But many parents sense there’s more going on. 

Colic isn’t simply a phase or a temperament issue—it’s often a signal that your baby’s nervous system is under stress.

Research and clinical experience increasingly show that many infants who experience colic later face ongoing challenges such as digestive troubles, sensory sensitivities, anxiety, or attention difficulties.

And rather than viewing colic as something your baby will outgrow, it’s time to understand it as your child’s way of communicating that their body needs help to reset and heal. When the underlying cause—often linked to birth-related stress or tension in the spine and nervous system—is addressed, babies can transition from distress to calm, setting the stage for healthier growth and development in the years ahead. So, let’s take a closer look. What should you, as a parent, know?

What Really Causes Colic in Babies?

For decades, parents and practitioners have debated what actually causes colic. The truth is, there isn’t a single explanation. Colic is best understood as a symptom—a sign that your baby’s developing systems are overwhelmed or out of sync.

Traditionally, colic has been blamed on digestive discomfort, such as gas, reflux, or food sensitivities. While these factors can contribute, they rarely explain the full picture. Increasing research points toward a more complex relationship between the nervous system, digestion, and stress regulation.

Your baby’s digestive tract doesn’t function on its own—it’s controlled by the nervous system, particularly through the vagus nerve, which connects the brain to the stomach and intestines. When the communication line is disrupted—whether due to birth stress, feeding challenges, or early tension—digestion slows, discomfort increases, and crying escalates.

In other words, colic is often associated with how your baby’s body handles and recovers from stress.

How Colic Affects a Baby’s Nervous System and Development

A baby’s nervous system is like a control tower—coordinating digestion, sleep, movement, and emotional regulation. When that system becomes overwhelmed early on, it can set the stage for patterns of tension that influence growth and behavior over time.

In many cases, the same stress that triggers excessive crying in infancy doesn’t simply vanish. Instead, it can resurface later as different developmental challenges. What begins as colic may evolve into sleep disturbances, digestive issues, or emotional dysregulation as your child grows.

When the nervous system is “stuck” in a stress state, it struggles to switch into the calm, parasympathetic mode needed for digestion and rest. This ongoing imbalance can affect how the brain and body communicate—impacting everything from gut health to attention and sensory processing.

A Common Timeline of Unresolved Stress Patterns

Although every child is unique, many parents notice a recurring sequence of challenges when nervous system tension isn’t fully resolved in infancy. This often follows a similar pattern:

• 0-6 months: Colic and excessive crying — prolonged discomfort, back arching, and irregular sleep patterns.
• 6-18 months: Recurring ear infections — often leading to repeated antibiotic use that can further disrupt gut balance.
• 18-36 months: Speech or developmental delays — delayed milestones, unclear speech, or limited verbal expression.
• 3-5 years: Sensory sensitivities — difficulty tolerating loud sounds, clothing textures, or busy environments.
• 5-10 years: Emotional and attention struggles — anxiety, difficulty focusing, or behavioral outbursts.
  

While not every child follows this path, this progression highlights how early stress patterns can influence later development. By supporting the nervous system early, parents can help children grow, adapt, and thrive more easily through each stage of development.

What Can You Do To Help Your Child Thrive?

As a parent, your instincts are powerful. If something feels off with your baby, trust that feeling. Persistent crying, tension, or difficulty settling aren’t just “phases” to wait out—they’re signs that your child’s body may be asking for help.

Begin by seeking practitioners, such as your Sioux Falls Chiropractor, who understand the nervous system’s influence on digestion, sleep, and development. Look for those who focus on the whole child, not just the symptoms. A provider trained in neurologically focused care can help identify and release the physical stress patterns that often begin at birth.

It can also help to reflect on your pregnancy and birth experience. Was there significant stress, a long labor, or interventions like induction, C-section, or vacuum assistance? These experiences can create tension around the upper neck and spine—areas crucial to nervous system balance. Understanding this background gives valuable insight into what your baby’s body might still be processing.

Additionally, focus on root causes rather than quick fixes. Remedies and dietary changes can ease discomfort temporarily, but lasting progress often comes from addressing the underlying stress in the nervous system. Keeping a simple journal of your baby’s sleep, feeding, and distress patterns can also help guide your provider toward the most effective support.

Most importantly, remember this: you are not failing. You are your child’s greatest advocate. With the right approach, your baby’s body can move from stress and discomfort to calm and growth.
