sounds promising! quinn first showed interest (i.e., she noticed what we were doing on the potty, heh) at about 15 months, so that's when we bought the first tiny potty to help encourage her interest. over the next few months she did her business sometimes in the potty. but she was 28-30 months before she was really PT. i think it could have happened sooner--we sort of slacked off for a while....
