About Four Trimesters
Supporting families through birth since 2002.
Singapore · Est. 2002
Four Trimesters is built on a belief that has not changed in over two decades: that how a family moves through pregnancy, birth, and early parenthood shapes everything that follows — and that every family deserves thoughtful, experienced, and deeply human support through that transition.
This is not a corporate maternity service. It never has been. It is the life's work of one practitioner — built over twenty-plus years, one family at a time.
Meet Ginny
Founder · Educator · Doula · Mother
Internationally respected birth professional with over two decades of experience
Ginny Phang-Davey has spent over two decades at the intersection of birth, education, and women's health in Singapore. She has attended over 1,500 births, taught antenatal education to thousands of parents, supported more than 1,000 families through placenta encapsulation, and trained over 2,000 birth professionals across Singapore, Australia, China, and beyond.
She has been a TEDx speaker — delivering the first globally recognised TEDx talk on pregnancy and birth, and the only TEDx Singapore talk on the subject to reach an international audience.
But the numbers are only the surface.
Ginny chose to become a mother at a time when unwed motherhood in Singapore carried real social and institutional consequences. She raised her first child, Kieran, alone — breastfeeding him for six and a half years, bedsharing for twelve, and taking the road she believed was right rather than the one that was expected of her.
Twenty-one years later, she became a mother again — this time to Hudson, conceived through IVF after two miscarriages, in her mid-forties. She is still breastfeeding him today, as he approaches his fourth birthday.
The gap between those two children is not just time. It is a lifetime of experience — professional and personal — that informs everything she brings to the families she supports.

2022 – 2024
What happened between 2022 and 2024
In April 2022, Ginny relocated to Miami with her family — stepping away from the Singapore birth community she had spent two decades building, to begin again somewhere entirely new.
She chose to homebirth Hudson in Miami — in a city where she knew no one. Her vision was intimate: her husband, her then 21-year-old son Kieran, and their three chocolate labradors present for the birth. Having completed studies at the National Midwifery Institute and spent time as part of a traditional homebirth midwifery apprenticeship with the Amish community, she understood birth physiology from the inside. She engaged a midwife with one request: to step back unless truly needed. The midwife attended the final twenty minutes.
She did not arrive with a ready-made support network. She built one — from nothing — after Hudson was born.
And then breastfeeding nearly broke her.
Hudson was born with a severe tongue tie. A laser frenulotomy was performed at five days postpartum — but breastfeeding remained painful. And then came the second layer: Ginny has sensory processing differences that make her unable to respond to breast pumps. In a situation where most lactation advice defaults to 'pump to build supply,' that option simply did not exist for her.
Despite having helped thousands of mothers breastfeed successfully, despite being a recognised expert in lactation support, she could not establish her full milk supply for four months. She relied on donated breastmilk in the gap. She troubleshot, sought help, and sat with the humbling reality of not being able to fix something she had fixed for others countless times.
There is something profound about being brought to your knees by the very thing you are known for. It does not diminish expertise. It deepens compassion.
She kept going. Her milk came in fully at four months. Hudson is still breastfeeding today, approaching his fourth birthday — a quiet testament to what perseverance through the hardest stretch looks like.
She also took three years of something that birth professionals rarely allow themselves: real maternity leave. She homeschools Hudson. She rebuilt slowly, intentionally, and on her own terms.
She returned to Singapore in late 2024 — and with her came everything those years had given her: a renewed sense of what families face when they feel unsupported and far from home, a deepened humility about how hard early parenthood truly is, and a rekindled passion for helping families reach what she calls the other side.

Our philosophy of care
Mother-centric. Evidence-informed. Choice-respecting.
01
We trust the birthing body — and we prepare families to trust it too
02
We honour informed choice — regardless of birth setting or path
03
We support families without judgement — for every kind of birth, every kind of family
04
We prepare parents not only for birth, but for the fourth trimester that follows
A good birth is not defined by a single outcome. It is defined by whether a mother feels heard, supported, informed, and emotionally safe — and whether the family emerges connected rather than fractured.
Birth does not end with delivery. How a mother is held — emotionally, physically, relationally — directly influences bonding, recovery, breastfeeding, and long-term wellbeing. This is why Four Trimesters supports families across all four trimesters, not labour alone.
Our aim is not control. It is capacity.
The brand name explained
What is the fourth trimester?
The fourth trimester is the period immediately following birth — broadly the first three months, though its effects extend well into the first year of life.
Human babies are born neurologically dependent in a way no other mammal is — at approximately 25% of adult brain size, requiring touch, feeding, proximity, and emotional regulation as developmental necessities, not luxuries.
At Four Trimesters, we prepare families not only for birth — but for this vital, often underestimated phase that follows it. It is the phase that shapes bonding, breastfeeding, maternal mental health, and the foundation of the family itself.
It is, in many ways, the most important trimester of all.

18months
The full human gestation — 9 months inside the womb, 9 months outside it
"Human gestation is an 18-month process: nine months inside the womb, nine months outside it."
