Yeah, I think we always share in the loss when a friend of family member loses a baby, especially in a circumstance like you described. That baby, born or unborn, is a member of our community, and we all miss out when the life slips away.
I know very much how you are feeling because coincidentally, I also have a friend who just lost her baby at ~8 weeks. She has always been a parenting role model for me, as she already has 3 children and handles herself so well with them. She's a LLL leader, has her kids in Waldorf, extended bf'ing, positive discipline... I learned a lot about how I wanted to do things by talking with her. She was so excited for me when I became pg with and gave birth to my DD and it was fun to finally be able to talk with her about my own experiences. This time around, we were actaully pg *together*
and the thought of that was really fun and joyous for both of us. Now we are mourning the loss of her child together.
It's very sad, but she has actually, once again, been a role model to me, as she has been very balanced about the whole thing and has amazing prespective on the situation. Death is just as much a part of living as successful preganancies and births. And I think we're all the healthier for it if we can truly accept and embrace that.
Sounds like you and your friend have a true, caring connection. You are lucky to have one another and I'm sure you will be sharing smiles and good times again soon.
