Yeh, I think that the baby wouldn't last too long.
And I don't think it would know that it's alive.
Even normal babies aren't conscious of being a living being until around one( somewhere around there at least), let's say. And that's with the normal stimuli. I think that the totally paralyzed and unaware person, even is they survived to twenty, would be forever stuck in the pre-conscious mind of a newborn.
