Chris,
Bud B's advice is the best and his prayer is echoed by us all.
For you personally, I worked for a while at Children's Hospital in Norfolk, VA...
I had to visit the NICU regularly to meet folks there... walking thru their watchin those tiny bodies hooked up to so many machines... one making their heart beat what looked like hundreds of times a minute... all the tubes, hoses, monitors...was the most terrifying thing I've ever seen!
And yet, many, many of those seemingly hopeless lil bodies grew strong and came thru and went home and developed into happy, healthy kids!
Our own Chip had much the same with his son having only half a heart I believe or it was hooked up backwards...and it took many surgeries before his boy came thru it...
Don't let HUMAN understanding undermine your faith or belief in the impossible when it comes to God and His children! Those tiny tots can take a lot more then we ever can...they just exist on Faith...without question.
Keep the Son in your eyes! Prayers continue!
