Your Baby’s Nervous System: Why Prenatal Health Begins with You
Every parent wants to give their child the best possible start in life. But with the growing rise in chronic health concerns—like allergies, asthma, ADHD, and autism—many moms and dads are asking an important question:
Is there anything I can do now to support my baby’s development before they’re even born?
The answer is yes—and it all starts with understanding the critical role your baby’s nervous system plays in pregnancy and beyond.
The Perfect Storm: A Pattern We’re Seeing Too Often
At Generations Chiropractic and offices like ours around the country, we’re seeing families come in with stories that follow a strikingly familiar pattern:
-
Fertility struggles and high-stress pregnancies
-
Multiple interventions during birth (induction, epidurals, vacuum, forceps, or C-section)
-
Newborns who struggle with latching, colic, reflux, poor sleep, or constipation
-
Toddlers or school-age children diagnosed with ADHD, anxiety, or sensory challenges
We call this series of stressors “The Perfect Storm.“ One challenge often leads to the next, creating a cascade that impacts both mom and baby—especially their developing nervous systems.
What the Numbers Are Telling Us
Let’s take a closer look at how common these experiences really are in the U.S.:
-
We lead in emergency birth care but rank last among industrialized nations in maternal and infant mortality
-
The U.S. spends over $50 billion annually on childbirth
-
Fertility clinics were a $7.9 billion industry in 2022 and are projected to double by 2028
-
25% of women are induced
-
70-75% receive an epidural
-
1 in 3 births are via C-section (more than double the WHO’s recommendation)
-
1 in 7 women experience postpartum depression
Although many of these interventions are necessary and lifesaving, we still need to ask: What can we do to better support mothers and babies before, during, and after birth?
The Nervous System: The True Foundation of Health
Most people think hormones are the key to a healthy pregnancy. But your hormones are actually regulated by a more powerful system—your nervous system.
Meet Your Body’s Command Center
Your autonomic nervous system has two key branches:
-
Sympathetic Nervous System (SNS): Also known as fight or flight, this system is activated in times of stress or danger. It raises heart rate, blood pressure, and muscle tension.
-
Parasympathetic Nervous System (PNS): This is your rest, digest, and heal mode. It slows things down, supports digestion, strengthens immunity, and promotes recovery.
When your nervous system is in balance, these two systems work in harmony. But when chronic stress dominates, it disrupts that balance—leading to physical and hormonal challenges.
HPA vs. HPG Axis: How Chronic Stress Impacts Fertility
Stress doesn’t just make you feel emotionally overwhelmed—it can completely reroute your body’s priorities.
-
The HPA axis (hypothalamic-pituitary-adrenal) controls your body’s stress response
-
The HPG axis (hypothalamic-pituitary-gonadal) regulates your reproductive hormones
When stress is high, the HPA axis takes over, and the body shifts away from fertility, reproduction, and fetal development. Cortisol and adrenaline dominate, while estrogen, progesterone, and other reproductive hormones get suppressed.
That’s why many women experience painful cycles, difficulty conceiving, or pregnancy complications during seasons of high stress. Your body is simply focused on survival instead of growth.
Your Baby Feels What You Feel
One of the most powerful (and surprising) facts about pregnancy is this:
Your baby’s nervous system is learning directly from yours.
The umbilical cord isn’t just a lifeline for oxygen and nutrients—it also acts like a power cord, transferring emotional and neurological signals between mother and baby. That’s why chronic maternal stress can influence fetal brain development and set the stage for future health struggles.
Your body’s ability to regulate stress helps teach your baby how to regulate theirs.
Nervous System Milestones in the Womb
Here’s a timeline to understand just how early your baby’s nervous system begins developing:
First Trimester
-
Week 3: Nervous system begins to form
-
Week 6: Sympathetic nerves develop (key for emotional regulation)
Second Trimester
-
Week 17: Cerebellum begins forming
-
Week 26: Vagus nerve begins myelination (insulation for communication)
Third Trimester
-
Weeks 33-36: Rapid brain growth
-
Week 37: Autonomic nervous system finishes developing
-
Week 40: Vagus nerve and immune system mature
These milestones show just how important it is for your nervous system to stay supported and regulated throughout pregnancy—because your baby’s entire blueprint is forming in real time.
What You Can Control
While you can’t always control your birth story or every external stressor, you can create a strong, resilient foundation before and during pregnancy by focusing on your own nervous system.

During Pregnancy
