It sounds like your daughter is mostly doing ok and that you're going in the right direction. My daughter is 9 years old and she still has problems holding her pee in too long, not telling anyone about it, then having another accident. My daughter always denies there is a problem too, until the last minute when she has to go all of the sudden, and may or may not be able to make it to a bathroom before she pees herself again. I feel awful for her, but nothing I try seems to help her get control.
If your daughter is already able to handle this most of the time herself, thats a great sign and you should be proud.
I dont quite see your concern on this matter, perhaps let her be in control of her own bathroom habits , in focusing on it you may make her anxious .
