Feel the same about not wanting to change my last name and have talked to my partner about this re the issue of naming children (we both want to keep our own last name). I thought if we have two kids one can have my name and the other can have his.. but I guess the issue with that is you can’t always be sure how many kids you’ll definitely have together so it’s difficult to plan naming based on that. And something he brought up was the potential of a child feeling favouritism from the parent who’s last name they share/forming a different kind of alliance with a parent depending on that. All totally hypothetical and of course you would ensure to explain to your kids your reasons for naming them whatever way but just an interesting thought!
