The Science Behind Building Healthy Habits as a New Mother
Building healthy habits as a new mother feels impossible because the usual rules don’t fit early motherhood: your motivation is fragmented, your cues are unpredictable, and rewards feel delayed. The fix isn’t more willpower—it’s working with the science of habit formation, starting absurdly small and anchoring new routines to the constants already in your day.
Why It Feels Impossible & Simple Strategies That Actually Work
Understanding the psychology of lifestyle changes during the transformative journey of early motherhood
When Everything Changes, Including You
Becoming a mother is arguably the most profound physical, emotional, and mental transformation you'll ever experience. Your body becomes the literal gateway to new life, and in the aftermath, you're navigating an entirely new identity while caring for a completely dependent being whose needs are as unpredictable as they are urgent.
If you've found yourself struggling to maintain healthy habits—or even basic self-care—during those early months (or years) of motherhood, you're not experiencing a personal failing. You're experiencing the very real psychological and physiological challenges that come with one of life's most significant transitions.
Today, we're diving into the science behind why healthy lifestyle changes feel so monumentally difficult during early motherhood, and more importantly, how understanding this science can help you build sustainable habits that work with your new reality, not against it.
The Perfect Storm: Why Motherhood Disrupts Our Ability to Build Habits
The Neuroscience of Habit Formation vs. Maternal Brain Changes
From a neuroscientific perspective, habit formation relies on consistent neural pathways in the basal ganglia—the part of our brain responsible for automatic behaviors. Under normal circumstances, it takes approximately 66 days of consistent repetition for a new behavior to become automatic, though this can range from 18 to 254 days depending on the complexity of the habit and individual factors.
However, the maternal brain undergoes dramatic changes during pregnancy and the postpartum period. Research shows that gray matter volume decreases in areas responsible for social cognition, while neural plasticity increases to help mothers bond with and respond to their babies. These changes, while evolutionarily advantageous for infant care, can make it challenging to maintain the cognitive resources needed for consistent habit formation.
The reality: Your brain is literally rewiring itself to prioritize your baby's needs over your own. This isn't a character flaw—it's biology working exactly as it should.
The Motivation-Habit Loop: When Survival Mode Interrupts Progress
Positive psychology research identifies three key components for successful lifestyle changes:
Clear motivation (your "why")
Consistent environmental cues
Immediate rewards that reinforce the behavior
Early motherhood disrupts all three of these components simultaneously:
Motivation becomes fragmented: While you may intellectually know that exercise and proper nutrition are important, your immediate motivation is often simply survival—getting through the next feeding, the next sleepless night, the next crying episode.
Environmental cues become unpredictable: Babies don't follow schedules, especially in the first year. The environmental consistency needed for habit formation is constantly shifting.
Rewards feel delayed or absent: The benefits of healthy habits—increased energy, better mood, improved health—often take weeks or months to manifest, while the immediate reward of rest or convenience feels more pressing.
The Science of Small Wins: Working With Your New Reality
Micro-Habits: The Gateway to Sustainable Change
Research by behavior scientist BJ Fogg at Stanford University shows that the most sustainable habit changes start incredibly small—so small they feel almost trivial. This approach is particularly powerful for new mothers because it works around, rather than against, the constraints of unpredictable schedules and limited cognitive resources.
The key principle: Start with habits so small that you can do them even on your worst days.
Examples of micro-habits for new mothers:
Drinking one glass of water upon waking
Doing five deep breaths before feeding sessions
Eating one piece of fruit with breakfast
Stretching for two minutes while baby has tummy time
Walking to the mailbox
Doing 1, 10-min video every day at about the same time
The Power of Habit Stacking
Habit stacking, a concept popularized by James Clear, involves attaching new habits to existing routines. For new mothers, this means identifying the few consistent elements in your day and building around them.
Formula: After I [existing habit], I will [new micro-habit].
Examples:
After I change baby's diaper, I will do five squats
After I start a load of laundry, I will eat an apple
After I put baby down for a nap, I will write down one thing I'm grateful for

Understanding the Timeline: Patience with the Process
Realistic Expectations for Maternal Habit Formation
While general research suggests 66 days for habit formation, the reality for new mothers is more complex. Several factors extend this timeline:
Sleep deprivation affects decision-making and willpower
Hormonal fluctuations impact motivation and energy levels
Schedule unpredictability disrupts consistency requirements
Cognitive load—mental resources are already stretched thin
A more realistic timeline for new mothers: 3-6 months for simple habits to feel automatic, with the understanding that there will be interruptions and restarts along the way.
The Non-Linear Nature of Progress
Traditional habit formation models assume linear progress, but maternal habit formation is inherently non-linear. You might maintain a habit for two weeks, then have it completely disrupted by a sleep regression, growth spurt, or illness. This isn't failure—it's the reality of motherhood.
Reframe: Think of habit formation as developing flexibility and resilience, not perfect consistency.
Pre-empting the Pitfalls: Common Obstacles and Evidence-Based Solutions
Pitfall #1: The All-or-Nothing Mindset
The trap: "If I can't work out for 45 minutes, why bother with 10 minutes?"
The science: Research shows that even brief exercise sessions (as short as 10 minutes) provide significant mental health benefits, including reduced anxiety and improved mood—exactly what new mothers need most.
The solution: Embrace "good enough" as genuinely good. Movement is movement. Nutrition is about progress, not perfection.
Pitfall #2: Comparison and Social Media Pressure
The trap: Comparing your behind-the-scenes reality to other mothers' highlight reels.
The science: Social comparison theory shows that upward social comparisons (comparing yourself to those you perceive as better off) consistently decrease well-being and motivation.
The solution: Curate your social media carefully and focus on your own progress markers.
Pitfall #3: Perfectionist Paralysis
The trap: Waiting for the "perfect" time or circumstances to start healthy habits.
The science: Research on implementation intentions shows that people who plan for obstacles and imperfect conditions are significantly more successful at maintaining new behaviors.
The solution: Plan for imperfection. Decide in advance what you'll do when things don't go as planned.
The Incremental Approach: Starting Where You Are
Week 1-2: Assessment and Foundation
Track your current patterns without trying to change them
Identify your highest-energy time of day (even if it's just 15 minutes)
Choose ONE micro-habit to begin
Week 3-6: Building Consistency
Focus on your chosen micro-habit daily
Add environmental cues to support the habit
Celebrate small wins consistently
Week 7-12: Gradual Expansion
Once your first habit feels automatic, consider adding a second
Begin connecting habits to create beneficial chains
Adjust expectations based on your baby's developmental changes
The Long Game: Why Self-Care Isn't Selfish
The Ripple Effect of Maternal Well-being
Research consistently shows that maternal mental and physical health directly impacts:
Child emotional regulation
Family stress levels
Long-term relationship satisfaction
Overall family resilience
The truth: Taking care of yourself isn't taking away from your family—it's investing in your family's long-term well-being.
Understanding how to build functional strength postpartum helps you create sustainable fitness habits. And when you're juggling the mental load alongside physical recovery, you're not alone—managing the invisible load of motherhood is part of every mother's journey.
Building Antifragility Through Healthy Habits
Antifragility, a concept from Nassim Taleb, refers to systems that get stronger from stress and volatility. By building sustainable healthy habits during the challenging early years of motherhood, you're not just surviving—you're developing the tools to thrive amidst the beautiful chaos of raising children.
Moving Forward: Your Next Steps
Remember that becoming a mother is not just about caring for a new life—it's about honoring the transformation happening within yourself. Your body, mind, and spirit are all adapting to this new role, and they deserve the same patient, nurturing care you give your child.
The science is clear: small, consistent changes compound over time. The key is starting where you are, with what you have, for as long as you can manage. Some days that might be a five-minute walk; other days it might simply be drinking an extra glass of water. Both matter. Both count.
Your challenge this week: Choose one micro-habit that feels almost too easy to fail at. Commit to it for seven days and notice how it feels to keep a promise to yourself, even a small one.

Dad Brain vs. Mom Brain: It’s Not You. It’s Not Him. It’s Biology.
“Mom brain” and “dad brain” describe a real difference in how parents process family life: mothers tend to think circularly—holding every need at once—while fathers tend to think linearly, one task at a time. It isn’t a character flaw or lack of love. Understanding the biology behind it helps couples stop blaming and start dividing the mental load by strength.
It’s Not You. It’s Not Him. It’s Biology.
*Disclaimer: I celebrate all gender identities and what I am about to say is intended to inspire and make you laugh with your partner. It’s okay if what I share is not true for you and your marriage…these are just my thoughts and reflections.
One of the greatest gifts of working with moms in-person is the conversations we have! Over the years, one topic has been a constant and common thread in EVERY conversation: how we, the moms, think about, plan and anticipate daily life is 180-degrees different from our partners. And the most striking part is that every mom's story about how her partner thinks is almost identical—yes, even for Ken and I.
Early on in my mothering journey, I attended a lecture at my daughters' school. With my little one asleep on my chest, I sat and listened to a talk that ultimately changed my life. Entitled, “The Overwhelm of Boys,” delivered by Kim John Payne. I went expecting to learn more about raising my children, and instead, I walked away with a shifted understanding of my husband.
As I made my way home, I called him at the restaurant where he was pushing out a Friday-night dinner service (we often joke about the number of times I’ve done this over the years!). I simply said, ‘I’m so sorry I have talked over you all of these years—I understand now that you need more time and space to think.” There was total silence on the other end of the phone while the clatter of the restaurant echoed in the background and then a quiet, “thank you.”
I got to thinking…what if we put these truths out in the open? We could understand one another better, communicate more effectively, and co-parenting can actually become fun! So, here are the not-so-secret secrets we all need to acknowledge and grow with:
Men and women are fundamentally different creatures with every respect for self-identity and gender identity. Acknowledging our differences helps us learn, grow, and lean into each other’s strengths.
Men think linearly. Women think circularly. And moms multitask like bad asses. We anticipate needs, we see the laundry, read the emails, catch the falling cup, and bounce the baby with one hand. In my experience, our brains almost function better in this arena—we just become more efficient when we have babies.
By contrast, male brains begin to smoke if you ask them to operate like this.
Men focus on singular tasks, but they DO the task all the way through until it has a bow on top. And, here’s the kicker…they won’t see or think about anything else while they are focused on said task. Meaning, the toys scattered across the living room, the dishes in the sink, the dinner that needs to be prepped…they are not pre-wired to see more than what they are doing. They can learn, but that is a relationship and co-habitational skill that you develop together.
One of the biggest pitfalls of marriage post-babies is that we are both overwhelmed and wanting the other person to think about all the needs of the home and family the way we do. When the other person doesn’t show up the way we expect, we slip into blame, which leads nowhere but down.
Divide and conquer based on your strengths, not what is “fair.” Most dads (like Ken) feel great accomplishment and a sense of deep self-value through the completion of a project. Most moms (including myself) are planning and creating the environment of our home and how each system will best meet our daily family needs.
Our winning solution? I plan the systems and Ken executes them. For example, new shelves for the girls’ closet that will better fit their bigger clothes and storage needs—I envision it, describe it, shop for it, he makes it happen. No fighting. I plan it. He builds it. It works.
Moms talk it out. Dads need quiet…in order to process their feelings. I call it “downloading” to Ken. It took him YEARS to be able to sit with me while I unleashed the workings of my brain and not get overwhelmed or try to fix everything.
Conversely, it took me YEARS to learn that when I talk at this pace and breadth, he needs hours to silently process everything. He will ultimately come back with a really supportive and insightful response, but only if I give him the quiet time he needs to get there. The faster we talk at the dads, the quicker their brains shut down their verbal center. They literally can't form a sentence. And, when they are quiet, what do we do? We talk more and faster at them because we process this way. They really need quiet space to get their thoughts together and form a response.
Learn reflective listening: It saved our marriage, truly. Fried mom and dad brains do not process accurately, which makes for sticky relationship communication. Reflective listening is when your partner is speaking about something, you simply repeat back what you have just heard. Literally, “ I am hearing you say ______.” And then, you check, “Is this accurate?” This technique slows everything down and makes sure you are hearing each other correctly. It cuts down so much frustration.
Prioritize each other’s need for friend time: Men need to be with men just as much as women need to be other women. But, when men become fathers, there is less social support for them in this area, especially if you don’t live close to where you both grew up or have family close by.
I put all of my weight and support behind Ken spending untethered alone time with his friends doing dude-like things that I honestly would never want to do—flying in his friend’s tiny plane, sleeping in a hammock on the beach without a shower for two days or even scrubbing the deck of a boat. In return, he puts his full weight and support behind my moms’ night out for guacamole and margaritas, where we get to talk as fast and on as many different subjects as our spinning mom-brains can cover…and no one gets overwhelmed. It’s like 6 months worth of mom-talk therapy rolled into one night!
At the end of the day, embrace and love the differences. They are your mutual and complementary strengths—you can both thrive in parenthood, marriage, and play with each other’s patterns instead of struggling over them. When the wheels start to come off, lead with curiosity and give each other the benefit of the doubt …and always remember, you’re both doing your best! x

The Mama Mental Load: Managing Motherhood’s Invisible Weight
The mental load of motherhood is the constant, invisible work of tracking, planning, and anticipating your family’s needs. It doesn’t switch off—and most moms were never given tools to manage a mind that never stops spinning. Embodied fitness offers one: movement that demands focus, training your attention while it strengthens your body.
Embodied fitness for the mom-life you deserve and want most.
No matter where you are on your journey, every mom needs to hear this…
Your mind is forever altered, consumed, and reordered as soon as you have babies. The topics you hold, lists you manage, and needs you anticipate to ensure your family is safe and thriving, will never leave you.
You most likely wouldn’t trade your new reality for anything, but you also grieve the loss of your relatively peaceful, pre-mom brain. However, much as you love your children, no one prepares you with skills and tools to manage a mind that is constantly spinning, has trouble focusing for more than 5 seconds, and can’t remember anyone’s name anymore.
You're not alone.
Nowhere does that statement hold more true than when it comes to caring for your body and working out. The days when the biggest challenge was just getting your booty to class are over.
Your new reality is that you’ll spend an entire class doing a tug-of-war with your brain bouncing around and your unprocessed self-needs clattering for attention. Then, after the class, you buckle up to greet whatever is going down at home.
It almost doesn’t feel worth it and that, my dear friends, is the biggest trap of all. The idea that your mind should somehow be able to compartmentalize and “turn off” is just not real.
Our mental and physical health go hand in hand. They directly relate to and impact one another—and that is the greatest secret we can optimize as moms.
So, now that we have established that your feelings are completely normal and we know you’re dying for the ability to deeply focus once again, we can tackle the topic of mindfulness and how it is cultivated in your real-life, mom experience.
When I say “mindful,” most of us immediately think of yoga or meditation. Those are wonderful practices that I enjoy deeply, but mediation is kind of torture these days—if I’m totally honest. As we have established, being alone with your brain to spiral is not productive for most of us. We need something powerful and challenging to train our minds and focus our undivided attention onto. What if your invested workout hours did more than lift your booty, but actually nourished you so that you walked away embodying the mom and woman you most want to be in the world?
That is where the opportunity of embodied fitness comes in!
Here’s how you’ll achieve just that:
Taking the time to learn how your body works requires mental discipline. You can’t zone out while you’re working out—especially with RM. By engaging the mind and body together, you’ll achieve the physical and the mental reset you want most, with a shorter time on your mat! Your workouts get efficient and effective because you are working more muscles in an integrated way, the entire time.
So, here’s your step-by-step roadmap:
Begin this year with Phase 1, Week 1 of the RM Method.
Follow the daily schedule of 30 minutes or less workouts a day and give your whole self to the workouts. No distractions—no checking your phone, fiddling with your hair, nothing!
Accountability + Motivation boosters are essential: Join the RM Inner Circle Group (it’s FREE with your membership!) on WhatsApp and receive daily love notes, inspiration, and feel empowered from other moms, just like you.
Love yourself when you feel stuck or feel like you’re failing.
Love your body. Love your temple. Remember, it birthed your babies.
We’ve got this…together, hands on each other’s backs.
