I called him Daddy until I was four. Dad ever since. I’ve always called my stepdad by his given name.
Father. We were old-fashioned that way (although my sisters and I also coined the nickname “Pudder,” which we used a lot, too).
I like my boys to call me Papa, and they do.
Papa, with short a’s on both.
Now it’s just Dad.
I called him Daddy when I was little, then transitioned to Dad sometime in elementary school. Then, in early high school, I started calling him Daddoo, which I’d heard on Animaniacs and liked. I still call him Daddoo most of the time.
My father was generally referred to as ‘that asshole’, and I never knew him. I called my stepfather by his first name.
“Dad” I’m white, in my early 30’s, and grew up in Michigan. My 2 1/2 year-old son calls me Daddy (sounds more like Da-yi). I assume it will transition to Dad later on.
Daddy, then Dad. Sometimes I still call him Daddy.
I’m white, in my early 50’s, and was born and raised in Houston, Tx.
Dead.
White, Jewish, late twenties, grew up in NJ. I called my father Daddy when I was little, Dad when I was between the ages of six or so and my mid-teens, when I reverted to Daddy. My siblings stayed with Mom and Dad after the switch, but I still call my parents Mommy and Daddy. This creeps out Mr. GilaB, actually, but tough noogies.
My mother says that I went through a brief phase at around six when I called her ‘Eema’ (the Hebrew word for mother, used by many of my peers), but I don’t remember it, or if I also called my father ‘Abba’ (Hebrew for father) at the same time.
I always called him by his first name. I think I picked it up from an older cousin, who for some reason never used “Aunt [Whoever]” or “Uncle [Whoever].” And my dad’s just that kind of person - almost everyone calls him by his first name.
ETA, I’m 41, and grew up in western Kansas.
Dad - 30s, female, white, grew up in Upstate NY.
Previous poll before we could poll.
Dad, but probably Daddy when I was really young. When I hear people use other words, it’s just jarring.
Wanja, while papa or vader is more usual in the netherlands. That’s just hoe my brother and me were taught. It was a nickname given to my dad by his nest brother, who thought my dad looked russian with his big beard. THE last five years i call him by his given name, becAuse hè usually has volunteers with him, and THE name wanja takes too much explaining. “hi! Can i speak to Reinder?”
I call my father “dad.” For some reason, he and his brothers called their father “Pop,” which I see has no votes yet.
I’m 40s, female, born/raised Chicago area. Dad is 70s, born/raised in Chicago & the suburbs.
20m Northern England. As One And Only Wanderers notes, everyone calls their male parent Dad here.
When I was little, he was Daddy. As I got older, that got shortened to Dad. Then I went through a “preppy” phase right around 1980 (as did half the country!) and started jokingly calling my parents “Mummy” and “Fa.” They thought it was funny–to this day they still sign things like cards that way. 
I’m Swedish so I voted pappa, which would translate into “dad”.
Old Man. However, that is a term from Ham Radio to refer to the guy that owns the rig. Dad, me and bro all have our licenses and when we found that in the study guide - Dad became Old Man.
Still is to this day, though he forgot to renew his license (still got mine).
Caucasian, Georgian, born mid 20th century CE.
I called him ‘Dad’ until I was about 15, after which I called him by his first name.
From the time I stormed out of my childhood home at the advanced age of 17 years old until I was about 22, I didn’t call him much of anything except ‘asshole’.
From 22 until his death a few years ago, he was ‘Dad’.
I miss my Dad.
