i suspect that she does know she is peeing in her pants during the day. she just doesn't care. she is busy playing and it is just easier to pee than interrupt what you are doing. so it back to square one with some remedial training. if she understands money give her a bag of quarters and tell her that she can keep all of the ones that are left at the end of the week. but if she pees in her pants she has to pay you two of the quarters (you can up the price as the training continues). soon she will get the idea. you will need to remind her to pee at least every hour or two so set the timer on the stove to buzz when it is time for her to go pee. if she does give her a quarter for her bag. good luck.
my potty trained 3 year old wakes at night to pee but does not know she is wetting herself during the day. she does have some accidents at night but wakes most of the time sometimes goes to the toilet during the day but mostly doesn't make it or urinates without knowing ie doesn't move wiggle is unaware until i point it out and say's she hasnt pee'd
