Hi, like you I tried potty training my child at ard 24 months but it was a complete failure, I figured she wasn't ready physically and emotionally. So instead of stressing us both, I stopped. I simply offer her a choice of diapers and very pretty princesses underwear during every diaper change. My rule for her is she can choose either one but if she chooses the underwear she would need to pee and poop in the potty. And I talk to her about using the toilet (show her how the toilet bowl works, how the flush works, how the potty works) and I place the potty near her play area. 7 months later at 31 month, she chose the underwear out of the blue and did very well. we only have very few accidents and they were very minor ones, like she pee-Ed a little in her underwear and was able to stop and rush to the potty.
My guess is your child is probably not ready either physically or emotionally, and stressing her about it may be counterproductive. This link below may help you.
