D.,
My daughter was very difficult to potty train...and in the beginning it was her training me; me rushing to get her to the potty, sitting there for 30 minutes where she would do nothing, and then as soon as she pulled that pull up on...tada...look mommy I went potty. ::sigh::
In the end it was a combination of things.
A) I removed the pull-ups. I realized she saw them as an extension of the diaper and wasn't really uncomfortable when she messed them. So I got rid of them and bought some normal training pants that let her know when shes wet. She did not like that sensation.
B) I made a game out of it. I created a board...one side for peeing. One side for pooping. Anytime she peed in the toilet I gave her a small sticker for her to place on the peeing side. Anytime she pooped I gave her a large sticker to put on the poop side...along with tons of praise, hugs, and kisses and the Im so proud of you...you are getting so big comments.
C) I was never negative. I never reprimanded her for her accidents.
D) I never rewarded with food. I did not want her to associate good behavior with food. So that is why i opted for the stickers.
and last....
E) I told her when she didn't potty for an entire month in her panties...then she would get her grown up panties of her choosing and a toy of her choosing.
With all of this. She did wonderfully...the stickers alone motivated her. Just make it fun. And keep it positive. It will be frustrating at time. But the key is to get rid of the pull-ups. Outside of bedtime of course. I also used the incentive that once she slept through the night with out going potty in her bed, regardless if she was wearing a pull up or a pair of panties, for one month, she would get a toy.
