Are they in any kind of danger?

Not really.  Thirty-two weeks is fairly close to the safety zone, since the NICU has done some amazing things with kids with much lower gestational ages.  Add to this the fact that our girls are proving to be relatively advanced for 32-weekers.  I'm not kidding about this.  Modesty prevents me from mentioning that Anna actually showed a suckling instinct today that we were assured shouldn't show up until 34 weeks gestational age.  They take after their mother, who was always a better achiever.  Both Anna and Evelyn took bottles of formula today even though tube feeding is de rigueur in the NICU.  Christa and Jen (each of whom had reason to know) both assured us that 32-weekers would look monstrously large compared to others in the NICU, and they were proven right.
