7 weeks actually is not that early. The mortality/morbidity rates especially with increased monitoring and medical technology now is so high it's not quantifiable, my personal estimate is he has a 99.9% chance or better overall.. Given the Hospital he was born in is one of the best in the country he'll be just fine.
My heart goes out to the woman we ran into on the way out of the ICU that had just lost her grand child...
We lost my first son early on in the year, I'm more worried and thinking of how I can help the people I've run into than the actual increase risks my son has. But I'm monitoring it all very closely. It's a lot to take in, especially a month and a half earlier than you were prepared to deal with it.
All I feel right now is love, and a grand desire to try to do better, for him, if I have to better my self in the process so be it, I just want what is best for everyone altogether, and trying to focus while diffusing on how to do that best.
The next few years are going to develop me more than my son I think. I hope the growth will reflect in him mentally more than physically.
