I talked to my son today and this is what he told he. They had a meeting with the gynecologist (spelling?) last night and she told them every scenario is possible. From going home with 3 baby's to going home with none at all. Last is of course worst case scenario. It's also possible the small twin brother is serving like a 'donor' for his brother and that means the small one won't survive.
She told them to be prepared for anything possible, to live day to day and try not to worry too much.
So I took out my embroidery machine and I'm going to make a winter quilt for my grandson. I have to do something and I don't want to make quiltblocks right now.
