Where the idea comes from
It starts with Igor Charkovsky, a Russian who pioneered water birth and, from the 1980s, took mothers into the Black Sea to give birth near wild dolphins. The stories attached to him are the ones that still circulate: a mother and newborn playing with dolphins within forty-five minutes of the birth, a dolphin escorting a baby to the surface for its first breath.
The second thread is the Sirius Institute in Pahoa, Hawaii, founded by Star Newland, which from the mid-1990s promoted "dolphin-assisted birth" and the idea of raising children alongside a pod. It ran, in some form, until the pandemic.
Both of those are worth knowing about because everything you will read online about dolphin birth — every blog, every listicle, every Pinterest board — descends from those two sources. There is no third strand. There is no clinical literature. It is one man in the Black Sea and one centre in Hawaii, repeated for forty years.
So you go to Hawaii. What happens there?
Hawaii is the right answer to "where". The Sirius Institute, on the Big Island at Pahoa, promoted dolphin-assisted birth from the mid-1990s until around the pandemic, and if you were going to do this, that is where you were going. So my first instinct — that there was a place — was not wrong.
What I did not expect is what its own website said: that it was still developing the dolphin-attended birth centres. Not running them. Developing them. That was the position for the better part of thirty years.
And the two famous Hawaii cases both turn out not to be what they look like. In 2013 a couple from South Carolina travelled there to stay with founder Star Newland and do prenatal bonding with dolphins before an intended dolphin birth. It went worldwide. The birth with dolphins did not happen.
The one everybody remembers
In 2015 a second story went round the world — a woman on the Big Island, filmed by Channel 4 for Extraordinary Births, apparently planning to give birth in the ocean with dolphins as midwives. It is almost certainly the story you are thinking of. It is the reason most people believe this happens in Hawaii.
After it aired, her partner went to the press to correct it. His words: "We never said anywhere or to anyone that we were planning on having a birth in the water with dolphins." They had planned a water birth in a pool in their own yard, which happens to overlook the ocean, and he said the film had implied something they never said.
What actually happened is lovelier than the version that travelled. She could not get comfortable in the pool, so she gave birth on the grass, by candlelight, at night. Their daughter is called Moana Hoku.
So the single most-cited dolphin birth in the world was a home birth in a garden, and the family had to say so publicly. That is the moment I stopped looking for a booking page.
What the claimed benefits are actually based on
The headline claim is that babies born this way hit milestones — walking, talking — around six months early. That comes from a research assistant working with Charkovsky. It is not a study. There is no control group, no publication, no follow-up, and no one has reproduced it.
The second claim is that dolphin sonar soothes the mother and the baby. Dolphins do produce powerful directed sound, and that is exactly why the claim is unconvincing in the direction people mean it: a dolphin’s echolocation is a physical pressure wave aimed at a body, not a lullaby. Nobody has shown a benefit and nobody has shown it is harmless to a newborn.
The Whale and Dolphin Conservation’s position on dolphin-assisted therapy generally is that there is no scientific evidence it is effective, and that both people and animals are exposed to infection and injury in these programmes. That is the whole category, not just birth.
The risks, specifically
The dolphins. Bottlenose dolphins are large wild predators, and in swim-with programmes they have rammed, bitten and tail-slapped people. The recorded injuries include lacerations, tooth rakes, broken bones, internal injuries and shock. They are not aggressive most of the time, but "most of the time" is not a standard you apply to a birth.
Infection. Around 32% of stranded bottlenose dolphins tested in South Carolina between 2012 and 2017 carried Brucella, which is zoonotic — it passes to humans. Brucellosis in humans can cause miscarriage. You would be introducing that risk to an open perineum, a newborn, and an umbilical stump, in unsterile water.
The ocean. Postpartum haemorrhage is the thing that kills women in childbirth and it is fast. In open water you cannot measure blood loss, you cannot keep a mother warm, you cannot maintain a sterile field, and you are — by design — a long way from an operating theatre. Every one of those is a problem independent of the dolphins.
A marine biologist at the University of Hawaii put it more bluntly than I would: hands down one of the worst natural birthing ideas anyone has ever had.
The part I did not expect to care about
The photograph at the top of this page is me with a dolphin, and I love it. I have also now read enough to know that the swim-with industry it came from is one that conservation groups have spent decades arguing against — for the animals’ sake as much as ours.
A dolphin birth requires a dolphin that will reliably turn up and behave. In the ocean, it will not. Which means in practice it requires captive or semi-captive animals, which is the version of this idea that is hardest to defend. The dream is wild dolphins choosing to be there. The logistics are a pen.
What the evidence actually supports
Here is the thing that made me feel better about all of it: the part of the dream that is real is the water, and the water is genuinely evidence-based.
The Cochrane review of immersion in labour found that labouring in water reduces the number of women who have an epidural, and shortens the first stage by around half an hour on average, with no evidence of increased harm to mother or baby. That is a real, measured, repeated finding.
What the evidence does not show is a benefit to the baby from being delivered under water, as opposed to labouring in it — both Cochrane and the American College of Obstetricians and Gynecologists are clear that no neonatal benefit has been demonstrated. So: water for labour, well supported. Water for the delivery itself, a preference rather than a proven advantage. Ocean, dolphins, no midwife — a different thing entirely.
If what you want is warm water, low light, no rush and the sound of the sea, you can have all of it, with a midwife in the room and a hospital thirty minutes away. That is the version I will actually be doing.
