I asked my OB when we would most likely be past the threat of NICU. She said with the boys measuring on track and my having had the steroid shot, they could probably go home anytime after 34 weeks!?!?
Does this sound right? Any 34 wk old babies get to go home right away?
Re: Twins born at 34 weeks
my hospital sends all 34 weekers - and younger to the NICU for observation at a min. I never had a steroid shot and my boys were in there for 13 and 16 days, born at 34w2d...mostly there to learn to suck, swallow and breath...only on cpap for the first 12hrs.
good luck!
33w4d-my baby girl went home after 5 days, and my son 9 days.
They had one steroid shot, and just needed to learn to feed, regulate body temperature, etc. I was SURPRISED how fast they got sent home, and the doctors/nurses mentioned being at home was the best thing for them once they got to a certain point. 
I had my babies at 35 weeks on the nose and neither needed any NICU time. We did have the steroid shot.
I think every day towards the end makes a huge difference.
