When was the term "dad" used?

-Was is at least 1950? I'm writing a story, taken place in 1954 and I'm curious if I can use that term, or I have to use like papa, father, etc.The TV show "I Love Lucy" was filmed and set during the '50s and when the Ricardos have their son he refers to Ricky as dad. The term itself dates to the 15th century.dad

recorded from c.1500, but probably much older, from child's speech, nearly universal and probably prehistoric (cf. Welsh tad, Ir. daid, Czech, L., Gk. tata, Lith. tete, Skt. tatah all of the same meaning).

I was born in 1952 and always called my male parent "Dad" or "Daddy," and I could talk by 1954, so sure, go ahead.
well depending on where one is from is the main point. Like me im from the middle east we say baba or abi. In some parts they say father and some say dad, papa.. it really doesn't matter.
You can use any term in your story. The word Dad is being used from a long time ago.
