I feel for you bro. My 2 year old daughter just had a 1/2" hole fixed in her heart. They were weeks away from having to do open heart surgery. Work is work, and we all put in our time, but the investment we make in our family takes so much out of us when something goes wrong. I get choked up a bit even thinking about it. I sincerely pray your little guy will come through this stronger than before, and with a great story to tell of God's grace.
