My June baby in May

My son's due date was June 12. May 15 my water broke at home and I delivered him at the hospital. We had hoped he'd be ok because I made it to 36 wks 0 days but unfortunately his lungs were not ready and he had an unknown infection. His lower right lung collapsed. Now we are waiting to see if he improves or if the entire lung collapses. He was 7lbs even and 18.5 inches long. The nurses in the NICU are shocked at his size and we hope it means it will be easier to recover.
