as for early training...I had a friend who serioulsy sat her daughter on the potty (more like held her up on it) from 6 months until she could sit on it herself. She was fully trained by 15 months. It was rediculous. Not the norm obviously and I couldn't actually believe she would go pee and poo at that age on the toilet but sure enough I saw it with my own two eyes. I have never and will never tell a daycare family that one or come a year and a half I will have kids showing up in undies LOL
