Born at 31+3, in the NICU for just under 5 weeks (discharged at 36+2). The major issues were bradys/desats and feeding. Her NG tube was taken out three days before discharge, and was the last major hurdle.
To chime in on the BF/bottle issue, I gave up my dream of exclusive breastfeeding and stopped pressing it when she was in the NICU. My girl would struggle and get worn out trying to breastfeed, fall asleep (and thus be un-bottleable) and that would go down in her chart as a 'failed feeding' and she'd have to get the NG tube. Every day she needed the tube was a day longer in the NICU. When I stopped trying to BF her and succumbed to the bottle, she had the tube pulled and was out in 3 days. Now that we're home, she is still not breastfeeding well--she gets tuckered out, falls asleep, and doesn't finish the feeding. I have to pump right afterward to keep my supply up, and then of course as soon as I've pumped she wakes up and wants to feed and my breasts are empty. Bottle has just been easier on both of us (her and I). She has to be starving to want to breastfeed, and I have to be engorged to produce milk at a rate that will keep her interested. Breastfeeding dream dashed, but at least we have her home...
