I can only tell you what I saw at our local NICU/SCN. There were twins born at 30 weeks, currently 34 weeks, wearing clothes from home, having cuddles from mum, and sleeping in a humidicrib. Just as I was discharged, they went to open air cots at 34 weeks. So it is going to depend on your babies, but at 1.5+ kilograms they are going to do pretty good, even from birth (usually). I know it is scary, but medicine these days is phenomenal. Thinking of you xoxo.
