Okay here's the deal...my SO is Korean and has identical twin sisters(also Korean). We are having twin girls in feb or march. Our girls are di/di so more likely they're fraternal not identical. Anyways, he wants to give them both the same middle name which is also the same middle name as both his twin sisters, which is Kim. Is this weird? I'm not sure how I feel about it...I mean I want to be understanding that he wants some heritage there and wants to name after his sisters bc duh TWINS but part of me feels like the whole thing is odd. All thoughts and opinions welcome!
