Hi, NewDad! Congratulations on the birth of little Samuel! Like others have said, the next few weeks and months are going to be a roller coaster. As much as I don't wish them on you, you will have plenty of bad days along with the good. Please know that there is a wonderful support system here if you or your wife ever need someone to talk to, vent to, cry with, etc.
It sounds like Samuel is one tought little guy. I hope he continues to do well and will be home with you soon! We know that your life is going to be pretty hectic in the coming weeks, but please try to update us if you get minute.
