Can a twin eat the other twin?
Listen. I was today years old when I realized the body can betray itself this early.
Not like, “Oops! I broke a nail.” No. I’m talking full-blown biological betrayal.
One baby. Eating the other. In the WOMB. 💀
Read that again and tell me that’s not horror film energy.
You think your childhood trauma’s bad? Imagine finding out you were supposed to be a twin…but your sibling got eaten before y’all even had birthdays. Yeah. This isn’t just a “fun fact” for TikTok. This is the kind of thing you process in therapy.
The Key Takeaway.
Yes, a twin can absorb another twin in the womb. But no, babies don’t “bite” or “chew” each other. It’s not like they’re fighting for the last slice of cake. It’s weirder, deeper, and way more emotionally messy than that. It’s about survival, timing, and the body being more savage than we like to admit.
Why a Baby Can’t Literally Eat the Other Baby in the Womb.


First, let’s clear the air. Because I know your brain is already picturing two little fetuses in a boxing ring, one winning, one getting swallowed like jollof rice.
That’s not how it works. There’s no womb-Hunger Games happening. No tiny teeth. No fetal buffet.
This thing is way more… quiet.
Sometimes, when a woman’s pregnant with twins, especially super early, the body just… absorbs one. The other twin? Keeps growing. The vanished one is just GONE. No gravestone. No funeral. Not even a sign.
Doctors call it “vanishing twin syndrome.”
(Which honestly sounds like a trick. Except it’s real. And it’s painful. And no one really talks about it.)
So, early in the pregnancy, one embryo stops developing. The body then absorbs the tissue. Just takes it back. Like a refund.
“Oops, never mind.”
And the remaining twin grows up alone. And what’s even more twisted is that most people never find out.
“Eaten” Isn’t Always the Right Word, but Emotionally? It Fits.
Look, medically speaking, nothing is “eating” anyone. It’s absorption. Biology. Blah blah.
But emotionally, let’s not pretend it doesn’t feel like an ambush.
The Most Disturbing Part: Some People Carry Their Twin’s Remains in Their Body.
No I’m not joking. I wish I was actually joking.
There are rare cases where what’s left of the other twin doesn’t vanish. It stays. Inside. Sometimes as tissue, sometimes as cysts, and sometimes as fully-formed weird structures like hair and teeth.
Yeah. Hair and teeth. Tell me biology isn’t a psychopath.
It’s called “fetus in fetu.”
Translation: One twin lives. The other becomes a guest that never leaves.
And in some cases?
The surviving baby doesn’t find out until YEARS later. Like they’re in their twenties or thirties and just casually learn they’ve been carrying their twin their whole life. Like an internal ghost.
Pregnancy Is Not a Joke.


We think birth is this beautiful, miracle-filled experience. But sometimes, it’s war. Quiet war. Survival-of-the-quietest.
One twin lives. The other… disappears.
- Not because they were weak.
- Not because they weren’t worthy.
- Just… because the body said so.
You Wanna Know What’s Crazier?
Some people who’ve absorbed their twin become OBSESSED with duality.
Split personalities. Talking to themselves. Feeling like they’ve “got someone else in there.”
Coincidence? Or is the body holding memories we’ll never understand?
I’m writing this in the middle of the night and the hair on the back of my neck is standing. I’m not about to have bad dreams, bye! 😂
