G.S.
That's so tragic. I had a friend who lost a baby, she needed people to tell her it wasn't her fault. But until you can get there, there are other things. As Toni and Julia and others have said, the meals are a great idea. I lost my "first baby" recently--my brother actually, but from the time he was a baby he was "mine." I have three girls now, and this is how I know I loved him like I love them.
When he died two years ago, I didn't want to be with people or talk to people or take a shower, or even get out of bed. And I didn't want people to see me that way. But to leave a meal on the doorstep regularly would make me feel as though someone who's a real friend cared.
I did have some close friends who did things like that and gradually were always there for me, no matter how strangely I acted, no matter how much I subconsciously lashed out--they were always coming back with more help, never taking offense, never pushing but just always there. I don't think I would have gotten through it if they hadn't been so "there" and so undemanding at the same time.
