Como dizer "Eu te amo, papai" em inglês

Happy Father's Day to all you fathers out there! My boy's five, going on six!

How a young child would say it:
"I love you, daddy!"

How an adolescent might say it:
"I love you, dad!"

How, if a male older than 15 might say it, it would sound very infantile:
"I love you, daddy!" (he should be saying "dad" and NOT "daddy")

How a kid in a strict family might say it:
"I love you, father."

Alternative ways to say it:
"I love you, pops!"
"I love you, old man!"

And to my very own old man, pops, father, dad and daddy:
"I love you, Bob! Happy Father's Day!"
