To me its weird, is it an american thing? Whats wrong with calling your mom and dad mom and dad?
I'm not American though. And English is not my native language.
But it just felt too close to continue calling them m'man and p'pa while I became an adult. I was a "rebel teenager" and didn't want to spend time with my family. Much less call them "mom and dad". And they stopped using the diminutive of my name years ago anyway. So I just did the reverse.
