Marriage is enough for some women to take their husband's last name while others wait until their children are born to make the change. Having a shared surname can make life a lot easier once a family starts dealing with life's paperwork and situations. Even after divorce or remarriage there are mothers that keep their ex's name to make matters simple. Of course, there are also ladies that never trade in their given names. Do you think it's important for a mom and her kiddos to have the same last name?
