In the meantime, the problem has a simple solution - when I married, I left a girl's surname and didn't change any documents!

I had a friend named Dubin, married, his wife naturally did not want to be Dubina, left her girlfriend.
A few years later, when the child in the kindergarten began to teach how to name mom and dad by fatherhood, he came home and asked:
“Mom, what are you unborn to us?
My mother thought and changed her name.
Good luck to you and your cats!

First, parents should explain to the child the name of their mom and dad, not in the kindergarten.
Secondly, a child at a young age does not realize the degree of affinity to the extent that adults can. So, with the teacher, you should find out the question of what heresy she blows in the ears of children.
