OMG dark knight I too had premature twins so I understand a little of what you are going through.
please let **nothing get between you and the safe delivery of your sweet baby and LIFE of your wife and little one**. You, of course, have totally done all the right things, and if baby needs blood so be it. Sadly relationships with parents in this situation take a back seat for now.
I hope with all my heart things go well, make SURE your wife bed rests as much as possible . Lets hope the delivery doesn't take place for another 4 weeks to be safe. I guess you know all the in's and outs by now, I'm sure the doctors have informed you.
Please please take care of YOU and your wee family and keep us informed as much as u are able, or feel like of course.Be assured our thoughts and love are with you.
