Pregnancy, week by week
Body, baby, inner weather, the person beside you — forty weeks, told honestly.
Open a week →You are growing a baby.
You are growing into a parent.
Some transitions are so big they ask for a new language. Ten Moons sits with you through one of them — from conception, through birth, into the first year — without rushing, fixing, or pretending it's simple.
Developed and curated by perinatal psychologists, family & couples counsellors, doulas, perinatal health & fitness specialists, and IBCLCs / lactation consultants. Educational — not a substitute for medical care.
The Ten Moons journey
Growing. Birthing. Becoming.
One companion across the whole passage into parenthood — first trimester, first contraction, first birthday. The same voice, the whole way.
Labor & birth, beside you
A contraction timer, phase-specific coping measures and partner guidance for the day itself — plus a place to decide what matters beforehand.
Enter Birthing →Postpartum & the first year
Recovery, feeding, the baby, the relationship, the weather inside you, the people around you. Coming soon.
Join the waitlist →Three parallel stories
Most apps tell you about the baby.
We tell you about all three of you.
01 — Baby
What's growing inside
Week by week, what's actually forming — from facial muscles to taste buds — told in plain language, and in millimetres rather than fruit.
02 — Body
What's changing in you
Why dizziness happens. Why digestion slows. Why sleep keeps shifting. The body changes most apps quietly skip over.
03 — Brain & Bond
Who you're becoming
Becoming a parent reshapes more than your schedule. We translate the neuroscience of that change — without pretending the hard parts away.
A week inside
Week 22 — open it up.
Eight short cards a week — the baby, your body, and you. Enough to feel oriented, and then you can put the phone down.
Baby
Taste buds developing
Hearing sharpens. Movement coordination improves.
Body
Center of gravity is shifting
Round ligament tension. Cardiac output rises.
Brain
Maternal anticipation networks strengthen
Dream activity often intensifies.
Reflection
What surprises you most so far?
A weekly micro-prompt — 60 seconds, just for you.
Partner
Baby hears your voice now
Tiny rituals that grow the bond before birth.
Movement
Pelvic circles for comfort
Evidence-aligned, never rigid.
+ A signature card
"What nobody tells you this week"
Why crying suddenly returns. Why the urge to clean a closet at midnight is real. Why two people can love each other deeply and still feel far apart this week. The honest things — named, and held.

What's growing
Taste and hearing sharpen
Flavors from your meals reach the amniotic fluid; baby is already learning the cuisine of your family.

What's changing in you
Round ligament tension is normal
Cardiac output rises ~30–50% in pregnancy. Slow stairs, sharper twinges, faster breath — all expected.

Maternal brain
Anticipation networks strengthen
Vivid dreams often intensify now — the maternal brain rehearsing scenarios. This is preparation, not warning.

You & baby
Baby hears your voice clearly now
Daily talking and singing builds prenatal recognition that newborns demonstrate within hours of birth.

For your partner
Belly-time for two
Hand on the belly, five quiet minutes, no phones. Co-regulation is a couple skill — and a baseline for co-parenting.

Move with care
Pelvic circles for comfort
On a ball or hands-and-knees. Frameworks like Spinning Babies support comfort and positioning, though high-quality outcome data remain limited.

Eat for two brains
Magnesium-rich foods for cramps
Pumpkin seeds, dark chocolate, leafy greens. Diet first; supplements only with your provider.

60-second prompt
What surprises you most so far?
60 seconds. No editing.

Open the full week →
Unique 8-card content for every one of the 40 weeks.
What's inside
Eight modules. One companion.
Nothing here is bolted on. Each piece exists because a parent, somewhere, said: nobody talked to me about this.
Body preparation
Breath, pelvic mobility, Spinning Babies–informed positioning.
Nutrition by stage
Iron in T1, magnesium in T2, anti-inflammatory in T3 — Mediterranean-friendly.
For the person beside you
Father-brain neuroscience, small rituals, and questions worth sitting with together — because not every conflict is a problem to solve.
Honest words to say to yourself
Not 'my birth will be perfect'. Closer to 'my body and my baby are learning each other'.
Mental-health check-ins
Early signs worth noticing, without treating every difficult day as a diagnosis.
Your Journey
Every pregnancy has a story.
Some pregnancies arrive unexpectedly. Others come after years of treatment, after loss, or far from home. Select what applies and Ten Moons will bring that material forward.
We will never classify you. We will try to recognize you.

After The Storm
Pregnancy after loss.
Long Awaited
After infertility or assisted reproduction.
Far From Home
Expat, immigrant, international families.
Later Bloom
Pregnancy after 35, especially 40+.
Solo
Single parenthood, by choice or circumstance.
Different Paths
LGBTQIA+ and alternative paths to parenthood.
The backbone
Warm in tone. Rigorous in evidence.
Every card shows where it comes from. We read the work — embryology, maternal neuroscience, perinatal mental health, the long literature on the transition to parenthood — and then we say it back to you in language that doesn't talk down or talk up.
We distinguish research findings from clinical guidance and from the questions worth discussing with your own care team.
Developed and curated by perinatal psychologists, family & couples counsellors, doulas, perinatal health & fitness specialists, and IBCLCs / lactation consultants. Educational content — not a replacement for your provider, midwife, or therapist.
