Mom, Mommy, or Madre (started when I was taking Spanish Class and she was encouraging (cough...annoying...cough) me to practice... so I started calling her madre to annoy her and it kind of stuck)
I call her by her real name in public usually because when your in a crowded store and yell "mom" way too many moms usually turn around.
When she is lecturing me on something I usually replied with "yes, mother".
So I guess I use almost every form... lol
