Honestly I don't really get it. To me having the same surname as my husband and children is a visible sign of being a family unit - not being made up of a blended family. That my husband is their father. but that's also why I got married. Might be traditional but that's the way I like it.
Yeah, this is spades. ^
I really don't see an issue with the woman just taking the man's surname, and the kids having his surname too. It makes life SOOO much easier. Don't care what anyone says, all having different surnames DOES cause issues throughout life. If it hasn't YET, it will do!
All this 'my kids are having MY surname, and he can deal with it' thing that some women come out with is just cringeworthy. And yes, as I and @londonqueen and several others have said, people will assume their father is the stepdad (if the mother and children have the same surname, and the dad has a different one.)
They may not say anything, but they will assume that, unless told otherwise. Sorry, but they really will, even if you think they don't.
I do roll my eyes at these women who say 'I am NOT taking HIS surname, and not giving my children HIS surname; because patriarchy!' And then go on to do the lion's share of housework, childcare, domestic duties. and life admin.
Seen it happen over and over. Refusing to take his surname, if they do get married, and refusing to let the kids have his surname, (because patriarchy!) but still sliding into the role of domestic servant!
