We day-trained my 2.5 yr old (32 mos) about 3 months ago, but she still won't tell us when she needs to use the bathroom, and has occasional accidents. I worry about her getting a UTI from holding her bladder for too long, and I also worry that she is not completely emptying her bladder.

If your toddler had a UTI, what symptoms did they experience? Was the testing for it very traumatic?
