34+5 preemie?

I was diagnosed with preeclampsia and while my physician is trying very hard to keep our sweet boy in, it looks like we may have to deliver earlier than 37 weeks. I've already had one shot of betamethasone for his lungs and I go today for the second. He is 34 weeks and 5 days gestation. I was hoping to hear from moms who had their baby around this time and how baby did as far as breathing, feeding and NICU stay. I'm so worried about him being okay I've cried most of the morning.
