Well, from birth to age 2, most parents are already trained to change diapers. I'd rather be trained to put my kid on the potty and not change a diaper.
We introduce the potty, make much ado about it, practice using it, then go straight to undies. We did this around 21 months with my first. SHe had an accident or two a week until 2, then was done. She had an accident or two a month until maybe 3 months after that. She told me when she needed to go, or just went.
