What we did was each come up with a short list of boy and girl names. We gave them to each other, crossed of the ones we didn't like and ranked the rest. We ended up with about 3 names. Then, with DS1, we waited to see what he looked like and chose that name.

If that happens to be the same name your friend has used, then so what? It's about what the child and adult will carry as their identity for the rest of their lives. Not what someone else thinks.

I kind of believe children choose their own name.
