dont know anything about a potty training guru, but i do know what worked with my sister, when i was potty training her. when she was about a year old, i bought a calender and marked the date that she would turn 18 months old, and told her that i would be introducing her to a potty in about six months, and then i marked off the days on the calender, and then when she turned 18 months old, i went out and bought her a potty and some "how to use the potty" books, and told her that big girls use the potty, babies dont. and you are a big girl now, so i am going to help you learn how to use the potty. no tears, no stress, and by the time she was two, she was completely potty trained, with no accidents.
