The soonest for the ability to exist, with a ton of equipment and help? Or the soonest without needing to live in the NICU?
This is a big difference, obviously. The longer baby stays where it's supposed to (the womb), the better chance for survival with less/none of the equipment to keep them alive. Babies can require the NICU at "term" too, so it all varies.
I think the very earliest born & lived was about 21 weeks, I think. But very scary and sad. A hard existance . :-(
