Hi Reddit. I (23f) and my husband (24m) are expecting a baby due in early 2026. For some background, my husband comes from a culture where it is accustomed for individuals to only carry the husband’s last name. In mine, we have both the last names of our parents. To the issue at hand-I’ve had numerous conversations with my husband where I explained to him that I want my last name to be first for our baby for a number of personal reasons. My husband is fully on board-his family isn’t. My in laws, whom we live with (long story) have asked us to reveal the name of our baby to them. We have refused time and time again, however my husband and I got so tired of this being an everyday pester to the point where we just told them. When we told them that our baby’s last name was (mine)(his), they flipped. They began to berate us, more specifically me, about how I could possibly think they’d accept this. They went on and on about how I was ending their (husband’s last name) lineage. It never occurred to me that this would be a legitimate problem, being this is something between my husband and I. Aita? Edit to add: It’s my house, the in laws live with me under my roof.
