We started early on to say "let's go potty", and I will bet our neighbors think we are nuts because, even though she is six, I still say it. She seems to not get as distracted if I keep her focused by saying it. I also tell her "let's go poop", and she does (I know when she usually needs to-once in the morning and once in the late afternoon). Funny, I can't really say that she is that well trained though. We do have our times when we find a puttle or a pile in the house.
