Mom and Dad (or Lynn and Michael, it took me a while to get the hang of the name thing).
My mother's parents were Grandma, Grandpa, and Grandpa Duggan.
My father's parents were Nana and Grandda (yes, without a final d).
BF's parent's are Mam (pron. like ma'am) and Dad (though not to me - I avoid all use of direct titles with his family if possible). His mother's mother is called Nana.
Until I was 15, Mummy and Daddy. Then I used their first names, as do my siblings. My daughter calls her grandparents by their first names, but calls me
Mummy, which I hate!
My mom is mom or ma.
I tried calling her Louise when I was a kid, but she told me I could call her by her name when I caught up to her in age.
I think I was around 13-14 before I caught that one and chewed her out
My stepdad is David, he's been David since I was 3 why should it change just because they finally got married?
My dad is dad or other, unrepeatable names.
My stepmother is 'that woman' or worse.
My mom is Mom, and my dad is Dad (or Daddy, I'll admit - I'm pretty much a Daddy's girl). I never knew my mom's parents - they both passed away when I was really young, but on my dad's side it was YeYe for my grandfather (Cantonese) but for some reason still Grandma for my grandmother. Yeah, I don't know why that is either.
I call my parents Mom and Dad. I used to call my mom Mommy. But my dad was always dad. My Grandparents on my moms side were Mimaw and Grandad. Dad's side Grandma and Poppy.
Mine were always Grandma and Grandpa, but when my son was about 2 or 3, he started this thing with my gpa calling him "bobo" so now thats what everyone calls him!! And thats been over 10 yrs ago.
My kids call my mom and my dad(god rest his soul) Papas, and my mom is Mimi to my daughter and Mamaw to my son and my in laws are Nana and Poppa.
I guess we kids just sorta shortened their names to make it easier to know who we were talking about. What is funnier is that my parents referred to their parents the same way...and still do to this day.
Mum's parents, though my memories of them are pretty sketchy, were Nana and Grampa. They both died when I was quite small, probably less than 4.
Dad's Mum was Nin, though where that came from I have no idea; I never knew his father, and he only ever referred to him as "my father", so I suppose I didn't miss much.
My Fathers side:
His father: Little Grandpa
His Mother: She died before I was born so I just call her "my dad's mother"
My Mothers side:
Her mother: Baba (The "Ba" sounds like it does in "Ball")
Her father: Giddo (rhymes with "key doe")
Her Grandmother: Big Baba ("Big" as in great, not large. She was only 4'10" tall)
