I have a question, me and my mam have had a huge argument resulting in my partner not wanting her to see our son. So long story short, me and my wife have been married 6 years come halloween. I gave birth to our son 4 years ago, now my mother during said argument mentioned the fact that my wife is not blood related to our son. And that she is his step mother. My question is, what is her title? I don't believe she's his step mother, she is his mother just as much as I am. We were married before he was conceived.
