No, I'd say it's just case by case, because I've heard when the baby was going to have all these supposed defects or whatever and the doctors encouraged the mother to abortion but when the time came the baby was fine.
I had a Neighbor girl when I was a kid who had some condition, her lips were purple, idk what she had exactly, the doctors said she wouldn't live long, she grew to about 13 or so until she died. That same family also had their first son die soon after birth, their other sons seems to fair alot better but then there's Ester, she was born with down syndrome.
I've had a cousin who only lived for hours.
Life isn't easy by any regards. But I still believe having that precious time to live is infinitely way better than to just snuff out a life.
