你这种两个孩子一个姓母亲一个姓父亲还是正常，但是有一个男孩一个女孩，肯定只能是女孩随你姓。如果你只有一个孩子或者你两个孩子都和你姓就不可能，说到底就是男方有“后”了，以后要嫁出去的女孩子就随你姓无所谓，和其他人说的冠母姓还是有本质的区别
It's normal for two of your children to have a mother and a father, but a boy and a girl can only have a girl's last name. If you have only one child or both of your children, it's impossible for you to have your last name.
