My daughter had this same problem and I took a different position. I told her that she was responsible for getting herself to the potty and not me. I stopped suggesting that she might need to go and we had a few accidents. I'd ask her what she was going to do about it and she would go and get a towel to clean it up (potty) and then I'd hand her a wet cloth. For poop, I had to supervise the cleanup more and also, I would hand her the poopy underwear to soak in the toilet. Then when I did laundry, I got her gloves to squeeze them out and then carry them to the washer. Basically I gave her as much of the cleanup responsibility as I could. That made it much more unpleasant for her and much less unpleasant for me. She only had a couple more accidents before she started getting herself to the bathroom on time.
