Hoya, (I have not read the whole thread), but as a mother of a once premie, I can tell you, as long as the issue was with your wife, your baby will be ok. Mine was. Neonatal is great, just make sure that her eyes are always covered, they didn't when my son was there, I think now they do. All the light hurts their eyes.
Good luck, she will be ok, mine did.
