After we found out about the donor, we decided it was time to set up a listserv for parents of the kids. Some of us had already been in touch through the Donor Sibling Registry, which is great for finding people but not so great for communicating as a group.
If I had contact information, I added someone to the group. I also messaged everyone on DSR asking if they wanted to be added. I even contacted someone from the donor's condolence website whose message hinted she was a parent.
Somehow, some way, the donor's mother is now a member of the listserv. This morning, she sent us all a message talking about her son. Wow. An excerpt: ... knowing that all of you strong and amazing women and your beautiful children are here is more of a blessing than I can express.
What a lady. Seriously. We will definitely be writing to her, now to figure out what to say.
