My dd was born at 30 weeks due to pre-eclampsia, but she was also iugr.
She was 980g and was in nicu for roughly 1.5 months, this was 6 years ago so my memory is not accurate on exact duration.
Upon birth (planned cs) she had a great apgar score and went straight to nicu with dh, I went to visit first the next day.
She was fed via longline at the beginning then through ng then expressed bottle fed before coming home. She needed cpap at beginning and the blue light for jaundice. But was off both within a week. We could hold her within a day or so and over the weeks gradually took over all the cares of nappies, clothes and feeding. The nicu staff were great, very organised and caring. There was a room for expressing and freezer storage of expressed milk. Hospital grade pump to rent really cheaply.
There was no judgement on how long you stayed with your baby. I noticed other mums wanted to stay all day but I preferred to visit for a few hours at a time several times a day/night instead and was never made to feel guilty.
My dd didn't have any ROP problems, and dodged NEC, she had a minor bleeding the brain, apparently this is a common thing with babies born at this gestation and had no problems from this to this day.
She did have an inguinal hernia (no idea if prematurity had anything to do with this) which was fixed at 3 months and a large facial birthmark, apparently also more common in premature birth.
These were literally all her "problems" from prematurity, but apart from the birthmark (which has ongoing treatment) and the general initial smallness there are thankfully no effects of being born that early.
What happened was unexpected and not pleasant but babies born at 30 weeks and even a bit earlier, even with iugr have great prospects to be ok.
Good luck to you, I wish you well!
