Donor Sibling!

A while back, I posted on my sperm bank’s sibling registry that I was expecting a baby girl on August 2nd. Since mine was a newer donor, I wasn’t surprised that mine was the first post.

But then the other day, I got an email from another mom who’s expecting a baby girl from the same donor! She and her partner are due in November, so my baby will have a donor/half sister just 2-3 months younger than her. I’m so excited! I never had any expectations that she wouldn’t have any donor sibs, and actually kind of wanted her to have them. Since my family is so small, and she may not end up with any siblings or cousins (ok, we have one pseudo-cousin who turned 6 today), I thought it would be really cool for her to have these other “family members”. Not necessarily a huge number, but a few.

I don’t have any specific expectations of what type of or how much contact there would be, but even just sharing pictures, stories, emails, etc. would be cool. And I’d definitely be interested in meeting other families in person at some point, unless my daughter just really wasn’t interested. But even when she’s young, I think it would be nice to have some sort of contact, and then things could always change if she got older and chose not to continue any sort of relationship.

So, I emailed the mom back, and she emailed me back again, and said she and her partner would definitely be interested in sharing pictures and having the girls write letters to each other when they’re a little older, and possibly meeting up at some point if the girls are interested, depending on how things develop. And that if there end up being other families who join the registry, maybe there could be a reunion in a different city every year or so. Sounds good to me!

I’ll send her pictures of my baby when she’s born, and I’m sure she and her partner will do the same, and we’ll take it from there. But what a unique, interesting experience it is to connect with another mom of a baby conceived from the same donor. I love it!

  1. My daughter has 20 half-siblings!! While the number sounds overwhelming, it is wonderful. We have had several reunions so far and meet up in smaller groups often. It is amazing to see how some of the siblings just click with each other and compare the similarities. I was nervous about contacting the group at first but it has become a great thing in both of our lives. I call them all my “in-laws.” 🙂

    1. My son is 14 months old and I know he has Donor Siblings out there, but I’m terrified to look for them!

  2. I am looking for a donor and am at a loss of how to choose. Your daughter is beautiful. Can you share how you choose or would you be willing to advise your donor information.

    1. This blog does not have a discussion feature, but our posts are usually written by our members, and many are from our 24/7 online Forum which has postings and conversations on all topics related to becoming and being a single mother by choice, including choosing a donor. If you’d like to join us, go to and choose the membership option. We’d love to have you with us!

  3. I’ve met my daughter’s sibling. We Skype about once a month and are planning another visit. We are 3000 miles apart, but want the girls to know each other. It’s great!

  4. I have met 2 of my son’s siblings and we enjoy a relationship with them and their families. It is not close as there is geographical distance, but the kids get along well.
