I didn't need bribes for my dd, she was a natural . Couple of days wiping up pee (no clothes, naked cute botty aahhhhhhhhh) and then sorted. Used pull-ups when out and about, had dd2 as well, no way was I dealing with accidents in the middle of Asda with 2.
One tip I used was I sat her on the potty when I was hanging washing up and said 'whose pants are these? whose top is this? etc ad nauseam and she sat there quite happily. Sent me mad however.
