With my father, sometimes daily and sometimes I may go a few weeks. With my mother, I may go months without talking with her. She lives 40 minutes from me and my father lives 4 hours. My mother has, I'll say, more going on to which I have subconsciously stayed away from. I have always had good relationships with both of them, so like u/one1won said, I grew up and my life got busy with my own family. My wife keeps in constant contact with extended family 4 states away and is puzzled that I don't call my mother on a daily basis.
