I call mine Mom or by her first name and daddy.

My father asked to never call him Dad. He said he would rather me call him a-hole than dad. For some reason he gets offended by it. He says dad is what you call a man who is your step dad.

Anytime I'm not talking directly to him, I refer to him as dad or my father.
