I felt draw to respond to your post. I am currently my fourth week of bed rest with my second child, but your post reminded me of my first child. I went into labor unexpectedly and it could not be stopped. We did not realize that I had an incomplete cervix until my second pregnancy.
My daughter was born at 26 weeks and 3 days weighing 1 pound 15 ounces. She went through struggles with an open heart valve, breathing, feeding, and weight gain among other things and spent 76 days in the NICU, but now she is 21 months and other than being smaller than her peers no one would ever know she was born premature. She is our little miracle.
I know your journey with your son will not be easy, but hang in there. Miracles do happen. You are in my thoughts.
