"Don't try to pull me by the shoulders, Tom, you'll misalign my pelvis," Sarah hissed. She was currently suspended upside down with her knees on our mustard yellow sofa and her forearms flat on the living room rug, her face turning a shade of plum you usually only see in expensive British jams.

"I'm not pulling your shoulders," I said, entirely unsure of where I was actually supposed to hold a heavily pregnant woman who had willingly turned herself into a human wheelbarrow. "But you've been upside down for forty seconds and the NHS leaflet explicitly said thirty."

My mother-in-law had texted us earlier that morning, her autocorrect acting as an absolute law unto itself: Are the babi in position yet? Have you tried that spinning babie thing the woman at yoga mentioned?

And so, here we were. Surrounded by half-assembled IKEA furniture, trying to convince two stubborn babies to vacate their comfortable breech positions by using gravity, sheer willpower, and a couch from 2018.

The bizarre mechanics of good fetal positioning

If you're currently expecting and haven't fallen down the physiological birth rabbit hole yet, you'll soon discover that "spinning babies" isn't a reference to a strange circus act. It's an entire methodology based on the premise that a mother's job in labor is to dilate, while the baby's job is to rotate.

Our midwife at the local clinic drew a wildly confusing diagram on a scrap of paper, explaining that our twin girls were facing each other like they were having a tiny, stubborn board meeting. She suggested we look into specific stretches and positions to loosen Sarah's pelvic floor ligaments and give them room to flip. She made it sound incredibly simple, as if we just needed to politely ask the girls to execute a synchronized swimming routine in a space roughly the size of a water balloon.

The forward-leaning inversion—the aforementioned sofa gymnastics—is supposed to stretch the uterosacral ligaments. You hang upside down for exactly thirty seconds, three times a day, to reset the pelvis. I'm no physicist, but watching my wife try to gracefully dismount from this position while carrying thirty extra pounds of human felt like watching someone try to park a bus in a bicycle shed.

The great pregnancy pillow barricade

What the diagrams don't tell you is the sheer, unadulterated volume of bedding required to maintain this so-called pelvic balance while sleeping. For three months, my side of the bed was slowly aggressively annexed by pillows.

Sarah couldn't just sleep on her side. She had to sleep on her left side, with a specific, dense pillow wedged between her knees to keep her hips aligned, and another smaller pillow between her ankles so her top hip didn't collapse inward and twist her pelvic muscles. Then there was the wedge under the bump, and the massive C-shaped contraption supporting her back.

By month eight, I was essentially sleeping on the extreme outer edge of the mattress, clutching the duvet for dear life, separated from my wife by a literal cotton fortress. If she needed to get up at 3am to pee—which she did, roughly every forty-five minutes—it required a dismantling operation so complex I'm amazed we didn't need planning permission from the local council. The sheer logistics of rolling a pregnant woman out of a six-pillow interlock system while half asleep is something no antenatal class adequately prepares you for.

We'd packed the hospital bag roughly eighty-four times by this point. Among the endless packs of giant maternity pads and tiny hats, we'd thrown in the Organic Cotton Baby Bodysuit Sleeveless Infant Onesie. Honestly? It was fine. It's a bodysuit. It kept the early days' meconium explosions somewhat contained, though I didn't actually figure out the physics of those envelope shoulders until the twins were six months old. It's soft enough, but trying to get it over a screaming, floppy infant's head at 4am in a dimly lit hospital ward still felt like trying to defuse a bomb with butter on my hands.

Fast forward to the toddler vertigo years

The cosmic irony of parenting is that you spend the last two months of pregnancy desperately trying to get your babies to spin, and then two years later, you'd pay hard cash to get them to stop.

Our twins are two now. They're fully upright, completely mobile, and entirely devoid of any self-preservation instincts. Their current favorite hobby is standing in the middle of the kitchen floor and rotating in rapid, jerky circles until their eyes lose focus and they careen headfirst into the fridge.

The first time I saw them do it, I assumed someone had slipped something into their morning milk. They'd just stand there, arms out like tiny airplanes, spinning until their little legs gave out, giggling maniacally on the linoleum.

I mentioned this to our health visitor during their two-year check-up, half expecting her to refer us to a neurologist. Instead, she looked entirely unbothered. She told me they actually need to spin for their brain development. She said something about vestibular stimulation and bilateral brain integration, which sounded suspiciously like the excuse my broadband provider gave when the Wi-Fi went down, but apparently, it just means they're figuring out where their bodies are in space.

They crave the dizzy feeling because it builds their postural control. They're basically stress-testing their own inner ears.

Embracing the centrifugal force of playtime

We probably should have seen this coming. Even before they could walk and hurl themselves into the skirting boards, they were obsessed with rotation.

When they were still largely stationary lumps on the rug, we used the Rainbow Play Gym Set with Animal Toys. I really loved this thing, mostly because it wasn't made of garish plastic and didn't play a tinny, distorted version of 'Old MacDonald' on a continuous loop that haunted my dreams. They used to lie underneath the wooden frame and aggressively bat at the little hanging elephant, making it spin wildly on its string. It was our first introduction to their deep, abiding love of centrifugal force. Plus, it looked relatively decent in our living room, which is a massive win when your entire house has slowly been overtaken by primary-colored baby paraphernalia.

Later, when the teething kicked in—which, for twins, feels less like a milestone and more like a continuous, decade-long hostage situation—we handed them the Bear Teething Rattle Wooden Ring Sensory Toy. They'd chew furiously on the untreated beechwood ring for exactly four minutes, searching for some relief from the gum pain, before realizing the crochet bear made an excellent projectile if they spun it fast enough by the handle before letting go.

So if your toddler is currently pirouetting in the hallway until they face-plant into the laundry basket, just move the sharp objects out of the way, throw down a soft rug, let them get delightfully dizzy, and accept the inevitable collapse while you drink your lukewarm tea.

You can browse the Kianao collection of wooden toys and play gyms if you're desperately trying to make your living room look less like a brightly colored explosion of plastic.

We spent months hanging off sofas begging them to rotate, so I suppose it's only fair they're getting their revenge by making us dizzy watching them do it now.

Highly specific questions about spinning babies (both kinds)

How long do you seriously hang off the sofa for the inversion?
The official recommendation we were given was exactly 30 seconds, not a second longer. If you try to push it to a minute thinking you're getting extra credit, you just end up with a severe head rush and a very annoyed pregnant partner who can't get back up without a crane.

Did the babies genuinely spin before birth?
One of them did, right at the last minute, turning head down just when we'd scheduled the C-section. The other one remained stubbornly sideways like she was lounging in a hammock. We'll never know if it was the sofa acrobatics or just dumb luck, but my wife's pelvic floor definitely got a workout either way.

Why does my two-year-old spin until they fall over?
Our health visitor assured me it's their vestibular system crying out for sensory input. They're mapping their center of gravity. It looks terrifying, and you'll wince every time they wobble near the coffee table, but it's apparently completely normal brain wiring.

Should I stop my toddler from making themselves dizzy?
Unless they're doing it next to a staircase or a roaring fire, let them crack on. If you try to intervene, they just wait until you turn your back and do it anyway. The brain usually protects itself—they'll just fall over on their bum when they've had too much sensory input. Just clear the area of stray Lego bricks first.

What on earth is pelvic torsion?
It's what happens when you sleep on your side with one leg thrown over a massive pillow and the other leg straight, twisting your pelvis and giving the baby less room to maneuver. It's also the excuse my wife used to permanently banish me to the outer two inches of our mattress for the entire third trimester.
