only going off my experience we all know each is different.
But well done on getting so far along, i am guessing you are around 30 weeks now?

Nixon was born at 33+3 weeks.
he weighed 2296g or 5lb 1 oz which is quiet a good weight. They estimated between 1.8kg and 2.2kg so he was a big boy!
He was on hospital for 27 days
NICU for 5 days, SCN the rest.
He was on CPAP within his first hour and ventillated after that until day 5
Our first cuddle was on day 5
He had a few hiccups which required a lumbar puncture, catheter and brain ultrasound.
However when he turned a corner he never looked back and just got stronger and stronger
First bf attempt was at 35weeks, for the first 4-5 days it was more of liking then actually latching on.

Like Sally said having a tour of NICU/SCN was very helpful for us just understand how babys a simialr gestation and size do and to also see your not alone, we were so surprised to see almost 60 bays FULL. (we were at the Mercy Melbourne which was fantastic)
