Mine wasn't prem or small, but was in SCN. I did get 2 hours skin to skin and could breastfed, but shortly after it was clear he had severe respiratory problems and they took him away and I wasn't allowed to feed due to them not knowing what was wrong, so he screamed from hunger for more than 24 hours but, nurses encouraged as much skin to skin, as that does help milk to come in, plus 3 hourly expressing, which was stored. They then used that to tube feed him. 48 hours later I was allowed to breastfeed. Just be there as much as you can. Most nurses will be encouraging you to express.
