Our daughter started potty training last month when she turned 3. She also needed the similar surgery that your daughter had. We are also experiencing the spotting just before she makes it to the potty. I have noticed it getting better with time. I've talked to other moms who don't have these medical problems they also have these problems. If it persists after the summer I'm calling the urologist but I don't think I'll need to because it is getting better. I'm just curious as to how long your battle has been going on. Good luck!
