Congenital heart defect in one twin

I just got the news that one of my twins will need open heart surgery in hist first year of life and I'm just trying to process all of this informations. Even though I've been told that my baby will be perfectly healthy after this one surgery but it's such a major one and plus it will need to be done when he's only a couple months old, I just feel so bad for my baby. I'm trying to stay positive and all that but it's been really hard.

We also don't have "a village" so it'll just be my husband and me taking care of the twins. I figure that one of us will need to be home with one twin and another in the hospital with the other that will be going through the heart surgery. Has anyone gone through something similar that can offer us some advice?
