I am curious how many people call their in-laws mom and dad? Growing up I remember my mom calling her MIL "Ma" and more recently my best friend has been calling her MIL "Mum" for years, before they were married as well (her MIL is from England so Mum is what her H calls her).
The thought of this never crossed my mind. I am very close to my parents and mom and dad are special names to the ones that have raised me. I also have a step mom and step dad whom I just call by their first name (I was about 16-17 when they each came into my life).
My SIL (we are both married to brothers) started calling MIL and FIL "mom and dad" as soon as she got engaged to BIL. (I had already been dating H about 3-4 years when she started dating BIL and they got engaged and married soon after). H and I have now been married 8 months and I sometimes force it but it just feels weird to me! I already have a mom and dad! I know I am over thinking it but H's parents are so sweet to me and consider me a daughter that it makes me want to show them how much I care for them as well (and I do understand I do show I care for them in many ways besides calling them "mom and dad").
As I struggle over here with either doing it or not doing it, I would love to hear what others have to say!
