The guide that everyone has been searching for, which is the #1 tip that most providers miss! Don’t forget that a regulated nervous system is the most important tool to have when going into the birth day. So let’s talk about how to prepare your nervous system for the most demanding autonomic event of your life. And then we will get into all the tips and tricks to try when it comes to preparing for birth!
Why Your Nervous System Is the Key to Birth Success
Labor isn’t something that happens to your body. It’s something your nervous system coordinates from start to finish.
Your Autonomic Nervous System has two main branches that work like a gas pedal and a brake. The parasympathetic branch (your brake) handles rest and healing. The sympathetic branch (your gas) provides energy and drives action. Labor follows a specific brake/gas/brake pattern:
- Parasympathetic signals must initiate labor. Your body needs to feel safe enough to start the process. This is why stress delays labor. Your nervous system won’t hit “go” when it detects danger.
- Sympathetic activation provides the energy to complete delivery. Those intense, powerful contractions in transition during active labor? That’s your gas pedal doing exactly what it should.
- Finally, parasympathetic recovery kicks in for bonding and breastfeeding. Your brake engages again so your body can heal and your baby can latch peacefully.
This sequence explains what conventional birth preparation misses. When someone tells you to “just relax,” they’re not wrong; they’re just incomplete. Relaxation helps, but only if your nervous system can actually regulate between these states.
Think about women whose water breaks, but contractions don’t start. Or labor that begins strongly, then stops. Or pushing that takes hours despite full dilation and positioning. These aren’t always positioning issues or “failure to progress” mysteries. Often, the Autonomic Nervous System is unable to make the transitions that labor demands.
How Stress Affects Labor (And What You Can Do About It)
Maternal stress doesn’t just make you feel anxious. It fundamentally changes your body’s labor readiness.
When you experience chronic stress during pregnancy, your body releases cortisol. Cortisol crosses the placenta and signals to both your body and your baby’s developing nervous system that the environment isn’t safe. High cortisol levels are associated with an increased risk of preterm labor, potentially necessitating medical interventions and complications during delivery.
The fear-tension-pain cycle demonstrates this perfectly. Fear activates your Sympathetic Nervous System. Sympathetic activation creates muscle tension. Tension increases pain perception. Pain increases fear. The cycle reinforces itself, and your parasympathetic brake, the system that needs to initiate labor, can’t engage.
Here’s what shifts the paradigm: preparing your nervous system IS preparing for birth. Not metaphorically. Literally.
This is where Neurologically-Focused Chiropractic Care comes into play. Subluxation, which refers to neurological dysfunction rather than just structural misalignment, can interfere with nerve signals coordinating uterine function, hormone release, and labor timing. Addressing subluxation during pregnancy isn’t about caring for a condition. It’s about optimizing the labor required for the communication system.
We measure this objectively using INSiGHT scanning technology, which measures heart rate variability (HRV)—a key indicator of nervous system adaptability. Higher HRV means your nervous system can shift smoothly between parasympathetic and sympathetic states. That’s exactly what labor demands.
Second and Third Trimester Preparation Timeline
Your body doesn’t flip a switch at 37 weeks and suddenly become ready for labor and delivery. Biological preparation follows a timeline, and when you align your actions with that timeline, you work with your physiology rather than against it.
Weeks 20-32: Foundation Building
Register for your childbirth class now, or sooner,if you want to complete it before week 36. 1 in 10 babies is born before 37 weeks, so we want you to feel prepared and ready!
Start building your nervous system support routine. If you haven’t already, this is the time to establish care with a provider who understands the neurological demands of pregnancy and birth. Regular chiropractic care during this window allows time to address subluxation before labor begins.
Weeks 20-36: Active Preparation
Start practicing labor positions now—squatting, hands-and-knees, side-lying, lunging, using a birthing ball. Your body loves muscle memory for these positions before active labor.
Begin perineal massages at 34 weeks. Studies indicate this reduces the risk of tearing, but only with consistent practice (5 minutes daily).
Finalize your birth plan. If you’re having a hospital birth or need an emergency bag packed from a birth center or homebirth, pack that bag by 36 weeks. If your baby isn’t head-down by week 34, talk with your provider about adjusting techniques that are specific to breech babies.
Weeks 37-40: Ready State
Stay active—walking, yoga, lighter lifting, swimming. Movement keeps your pelvis mobile and your nervous system adaptable. Both matter for labor progression.
Monitor for signs of labor: regular contractions that increase in intensity, water breaking, bloody show, and mucus plug loss. Know your provider’s specific instructions about when to call.
Plan to labor at home during early labor if you’re low-risk for as long as possible. Your nervous system feels safest in familiar environments.
The HRV Phenomenon
Heart rate variability (HRV) reaches its highest pregnancy values approximately 7 weeks before birth. Your body enters intensive training mode for labor’s autonomic demands during this precise window. This is why supporting your nervous system function through weeks 33-40 isn’t optional wellness; it’s working with your biology during the exact window when your body is most receptive to optimization.
6 Essential Tips to Prepare for Birth
1. Take a Comprehensive Childbirth Class
Knowledge reduces fear. Fear increases sympathetic activation. That’s not a metaphor, it’s physiology.
Childbirth classes teach you labor stages, breathing techniques, pain management options, and when to head to the hospital. Look for classes that cover both medicated and unmedicated birth options. Your partner should attend too.
2. Optimize Your Nervous System Through Neurologically-Focused Chiropractic Care
Subluxation can interfere with nerve signals that coordinate uterine function, hormone release, and labor timing. Labor requires precise nerve communication, triggering contractions at the right intervals, releasing oxytocin at the right moments, coordinating cervical dilation with descent, and sequencing the brake/gas/brake pattern.
INSiGHT scanning technology provides an objective assessment of nervous system function—you get visual data showing where interference exists, then tracking how it changes throughout care.
Regular care matters more than one-time adjustments. Your nervous system needs consistent input to establish new patterns of function. Starting in your third trimester gives you the preparation window your body needs.
3. Build Your Support Team and Create a Birth Plan
Choose a health care provider aligned with your birth philosophy. Consider hiring a doula. Research shows that continuous support from a trained birth companion improves outcomes.
Your birth plan documents your preferences, not predictions. Include: lighting and environment, pain relief preferences, who you want present, skin-to-skin immediately after birth, delayed cord clamping preferences, and feeding plans. Discuss your plan with your provider by week 32.
Add this question most birth plans miss: “How do you assess when intervention is necessary versus when labor needs more time?” Their answer reveals whether they understand that labor has its own timeline.
4. Practice Birth Positions and Stay Active
Movement during pregnancy keeps your pelvis mobile and your nervous system adaptable. Aim for 30 minutes of activity, 5 to 6 days per week.
Practice labor positions now: squatting (opens pelvis, uses gravity), hands-and-knees (relieves back pressure, helps posterior babies rotate), side-lying (rest position that allows progress), lunging (helps positioning of baby), turning toes and knees inward (helps baby work down and out of the pelvis), and sitting on a birthing ball (encourages descent and hip mobility).
Starting around week 34, optimal fetal positioning techniques can encourage your baby into the best position for birth.
5. Learn Pain Management Options and Understand Interventions
Unmedicated techniques: Deep breathing patterns, hydrotherapy (shower or bath), massage and counterpressure, position changes, focused relaxation, squeezing a birth comb, water injections at the site of pain, etc.
Pain management works best when your nervous system isn’t already in overdrive. If you start labor from a regulated baseline, pain relief techniques—whether medical or unmedicated—work more effectively.
Common interventions include induction (using Pitocin to start contractions), vacuum or forceps assistance, and cesarean section. Each can be lifesaving when needed. What’s important is understanding how each affects the natural nervous system signals coordinating labor, if you do have a choice.
6. Prepare Your Mind Through Daily Stress Reduction
Nervous system preparation is also helping you prepare mentally. They’re not separate.
Build daily relaxation practices now: 10 minutes of meditation, monthly prenatal massage, walks in nature, journaling, watching positive birth stories, listening to positive podcasts, building a birth playlist, or whatever helps you downregulate from daily stress. The pattern you establish now trains your parasympathetic response for labor.
Limit exposure to negative birth stories. Visualize a positive birth experience, but don’t script every detail. Visualization isn’t wishful thinking; it’s rehearsal. Your nervous system doesn’t distinguish between vivid imagination and reality when building response patterns.
The “Perfect Storm”: Why Birth Preparation Affects Your Baby’s Future
Most birth preparation guides care for labor as an isolated event. But Neurologically-Focused preparation goes deeper, because the nervous system environment you create during pregnancy shapes your baby’s developmental foundation.
The “Perfect Storm” framework explains how prenatal stress, birth trauma, and early childhood stressors converge during critical developmental windows.
Your baby’s nervous system develops in the environment created by your nervous system. When you experience chronic stress during pregnancy, cortisol and other stress hormones cross the placenta. Research shows that high maternal stress during pregnancy affects the infant’s nervous system reactivity by 22%. Babies born to highly stressed mothers demonstrate stronger stress responses and poorer recovery from challenges after birth.
Birth trauma and interventions. Physical stress during delivery, whether from C-sections, forceps, vacuum extraction, or prolonged pushing, creates neurological impact. The upper neck and brainstem area are especially vulnerable. This is where critical nerves exit the spine to coordinate digestion, sleep, immune function, and emotional regulation.
Subluxation from birth trauma doesn’t always show immediate signs. Sometimes it shows up as colic, reflux, or constipation in the early months. Sometimes it remains subclinical until developmental demands increase, then it appears as sensory issues, ADHD, or anxiety years later.
Early childhood stressors. After birth, environmental factors compound prenatal and birth impacts. Repeated antibiotic use disrupts the gut microbiome, which affects nervous system function. Environmental toxins, frequent infections, and delayed motor milestones—each adds stress to a nervous system already working with whatever baseline was set prenatally and during birth.
How Neurologically-Focused Chiropractic Care Interrupts the Perfect Storm
When you address subluxation during pregnancy, postpartum, and for the baby after birth, you’re optimizing the developmental environment before your baby is born. When you prepare your body for labor through nervous system optimization, you improve the likelihood of a smoother delivery with less intervention. When your baby receives a chiropractic assessment soon after birth, any subluxation from delivery can be addressed before it compounds.
This is preventive care in its truest form, preventing the neurological cascade that makes children vulnerable to chronic health challenges as they grow.

Your Body Was Designed for This
Birth preparation comes down to three layers: physical, practical, and neurological. Conventional wisdom covers the first two. What most guides miss is the foundation. Your nervous system’s ability to coordinate the most autonomically demanding event of your life.
When that foundation is strong, everything else works better. Pain management becomes more effective. Labor progresses more smoothly. Interventions become less necessary. Recovery happens faster.
You’re not just preparing for a day. You’re creating the neurological environment in which your baby develops. You’re setting the foundation for their health trajectory. You’re interrupting the “Perfect Storm” before it forms.
Your nervous system is the most sophisticated birth technology on the planet. More advanced than any hospital equipment, more precise than any intervention, more powerful than any medication. Give it the support it needs. Remove the interference preventing optimal function. Trust the wisdom built into your biology.
