AIBU to think a foetus is alive before birth?

I had a discussion with someone, who believes that a foetus is not alive, until the point they are born. They also asserted that this was not an uncommon view. I have a hard time believing this so I'm putting it to the AIBU poll.

To be clear, I'm pro choice, but I do believe that, for example, a 30 week foetus is factually, scientifically considered to be alive.

Surely, even if you're pro-choice all the way up until birth, you accept that the foetus is alive?

YABU = A foetus is not alive, until birth.
YANBU = A foetus is alive in the womb.

Yes, my 22 week gestation baby that parties all night doing back flips in my belly is very much alive.

My son was born at 30 weeks. I believe a foetus is alive but not aware.

So do you think the nerves become ‘activated’ at birth?

BatchCookBabe · 19/03/2026 20:03

Of course a foetus is alive!

catspyjamas1 · 19/03/2026 20:08

Aren't most medical issues caught earlier now? And the necessity is very low? @sisterinlawunkind

Or psychological reasons. I don't think whether a foetus is alive is the primary consideration. The mother's autonomy of choice and wellbeing is paramount.

And there it is.

As I thought.

Did you rub your two brain cells together really hard to make that thought. Don’t wear yourself out.

They start to feel pain between 24 and 28 weeks gestation.

OK?

Well tbh I’m not sure I understand the point of mentioning adoption?

Yoheresthestory · 19/03/2026 20:21

They aren’t alive until they can live in my opinion. Before that, they are part of the mother’s body. So until they can survive on their own is the line for me.

What do you mean by this? "having euthanasia available post birth for babies born with life limiting conditions who will suffer in pain for a few days/weeks before passing naturally."

I mean exactly what I said.

Some babies are born with severe abnormalities that mean they will die within days/weeks and will suffer in pain their entire short lives. We should be allowed (with the parents consent) to allow these babies to pass quickly and not languish in pain. Not everything is treatable and where treatment isn't available, euthanasia should be.

The thing is a 30 week old fetus could possibly (probably) survive outside the womb.
A 12 week fetus couldn’t.

I was born at 26 weeks 44 years ago.. I was definitely alive.

PollyBell · 19/03/2026 19:40

Well they should be, if someone harms a pregnant woman and the baby dies it shoulf be murder

But people say they lose a baby when they have a miscarriage but go on about it only being only cells when they want an abortion

Edited

Of course they should, I agree but unfortunately they wouldn’t be charged for murder.

When people miscarry usually those people actually want the baby so see it as a baby. Even in the very early stages, they loose a baby and grieve the baby, toddler, child that they have just lost. People having an abortion don’t want the baby and will tell themselves it’s only cells to make themselves feel better

thankgoodnessforpuppies · 19/03/2026 20:27

Of course they're alive. They're not independently alive as they rely on the mother for life support, but they're an alive individual human. They do interact in their way with the environment. You can feel that when they are inside you.

What do you mean, so if a baby (like me) is born at 26 weeks and needed medical assistance to survive is that baby not a being in your opinion. Or do you mean before the stage that medical assistant couldn’t save… Like a 12 week pregnancy.

Something with brain activity and a beating heart is alive

Crushed23 · 19/03/2026 20:41

“Alive” is an irrelevant concept.

I’m completely pro-choice and I would consider a zygote “alive”.

Really?

StillWeRise · 19/03/2026 21:00

love to all those here who have lost babies
and also those who have had to terminate pregnancies for whatever reason

but

this alive/not alive debate is entirely irrelevant to the ethical dilemmas around termination, since we happliy and legally destroy life daily

its hard to imagine a woman who has gestated and given birth can claim to believe a foetus is not alive. If I was OP I would concentrate on trying to get the friend to think through exactly what she means by 'alive' and why she thinks that

good luck OP, I share your bafflement

Yes. I see you could be. A fetus is alive. What I meant was they can’t survive before a certain age.
Not sure what your point is ?

gamerchick · 19/03/2026 21:08

It's a weird question.

An unborn baby is classes as a parasite, it surpresses the immune system and takes what it needs from your body.

A tapeworm does similar. Is that alive?

You're either alive or you're not.

What you're asking is do unborn babies have any rights to go on living outside the body. Not whether it's alive or not.

Yes I was quoting the person who said they were not aware

No, she's merely asking if it's alive. It's been argued that it's not a living organism at all, which frankly doesn't stand up to science or common sense.

But babies can't survive independently either. They rely on someone to feed them, keep them warm, looks after them etc.

They don’t rely on another body to survive though. A baby can live separately from a woman whereas a fetus can’t.
