Will be praying for your granddaughters! The things they can do today is so wonderful. We have had three in neonatal intensive care over the last few years and one of them was one of our twins. Not as serious as yours but I have seen babies in crisis in there and they have pulled them through.
Jesus is with them watching over them as they struggle through this crisis. May he surround you all with love and comfort!!
Looking forward to the day they get to come home!!
