This is an issue that my DH and I are also dealing with. We don't have any kiddos yet, but since I kept my last name when we married, and DH has his last name, we're not sure what we are going to do about last names of our children. DH is all for giving the children a third last name, but I'm not completely sold on the idea. I'm glad someone posted who said they liked having a unique last name because I always thought it would be awkward for a child. Last names are pretty important to me, which I guess is why I felt so strongly about keeping mine. I have a very unique last name, and I only know 5 other people who have it. My dad changed his last name when he was in his 20s, so I was the first person born with the name, and I kinda like that small fact! At any rate, good luck with deciding what to do with your LOs last name. I don't really have any advice, I just wanted to chime in since we're dealing with the same issue.
