the most common cause of enuresis in a toilet trained child for more than 6 months is urinary tract infection , she may not have fever but still she can have it . for that a urine analysis and urine culture is needed and of positive , antibiotic toward the bacteria found in the culture is prescribed . but if the culture is negative , then try to take more notes about how many times she do it through the day and if possible measurement of the amount is advisable , and that is helpful in the diagnosis of neurogenic bladder , latter on she needs ultrasonography of the kidneys and bladder . careful exam is needed for evaluation , both genital and back exam is very important in cases of enuresis . so I highly recommend to take her to the pediatrician to examin her and assess her condition. I hope this helps
