answer:In today’s world, mothers often have different last names than their children, so I wouldn’t worry about feeling uncomfortable in school settings and the like. Since I’m divorced from their father and have remarried, I now have a different last name than my children and it’s not a big problem. The only con is that people who know you primarily through your children will refer to you by their last name…I am often called “Mrs. Children’s-last-name” at school or the doctor’s office. Since it’s my ex-husband’s last name, that could have been an irritant, but it’s no biggie. More and more, I like the idea of combining the two last names for children, either by hyphenating or making up a new name altogether that reflects both last names. For Smith and Johnson, for instance, it could be Smithson.
