Hi Vanessa, my middle son was born at 25 weeks, 1 lb 11 oz, I was not even allowed to take him out of his isolet until he was 2 lbs, which was a great day! Meanwhile, we had an outstanding lactation specialist at the NICU (my husband called her the Breast Police, cause if we got below a certain number of containers of BM in the NICU freezer she would be on the phone!) I rented a fantastic pump from the hospital, it was NOT covered by our health insurance, but it was SO VERY much better than any pump I had ever used....
The hospital was very nursing friendly, I even brought in a bottle of wine to have a nip while I was holding my son and pumping in the NICU. He was fed BM through a tube while I tried to hold the pacifier in his mouth to develop those sucking muscles. It was not easy, I also had an 20 month old toddler.
We pretty much lived at the hospital. A staff member would amuse my older son while I pumped, drank wine, rocked the preemie with a binky in his mouth.
I pumped at home 'on demand' as if I had a baby to nurse. I didn't work so I had the time and the inclination to do it, it WAS a lot of work.
He only was just learning to latch about a week before he came home three months later, at4 lbs.
They were concerned with growth, so they suggest Alimentum as a supplement to BM since he'd been taking a bottle well, I mixed it half BM half Alimentum (sewer water my husband called it, awful stuff!).
I WAS able to nurse him (though not exclusively) until he was about 8 months old (5 months gestationly)....
I had TONS of support though and all the time in the world to make it work.
Most important thing was really he had BM from his tube and nothing else. And that he was getting bigger making progress.
My other two children were exclusively nursed so I was determined to make it happen.
He is now a normal healthy 16 yo junior in high school and frankly the very LAST thing on my mind is whether or not he was BF or bottle fed.
You bond with her feeding from your breast or a bottle, the important thing for her is your intense mom love and closeness.
Please don't beat yourself up if you cannot exclusively BF. I admire you for even trying!
Good luck and congratulations!!! Hope this helps!
