Delivery on Friday!

So I’m now scheduled to have my c section this coming Friday at 36 weeks instead of 37 weeks. Twin A dud not grow as much as they wanted her to and are worried her placenta may be not doing it’s job correctly. So they said she will grow better out rather than in. She only weighs 4 and a half pounds right now though, so I’m very nervous for her….twin B is already weighing in a just over 5 and a half pounds and they don’t think he will need any NICU time. Anyone have any advice? Any positive stories about their premie twins to share? Just feeling a bit of a nervous wreck right now….
