This was my dd, now 3.5. She didn't fully learn to use the potty until about 3 months ago. I tried stickers, candy, new panties, praise, everything. So, I started to set the timer for every 2 or 2.5 hours and remind her to use the potty when it would go off. Ultimately, it came down to her choosing to do it. Also, I had to fully get rid of the pull ups because if she had them on, she would just go in them.
