I have a 34 month old. About 3 weeks ago I notices some brown and/or black specks in her urine but didn t see anymore any other time. Yesterday and today, I have again began to notice them. Once yesterday and twice so far today. I would think it would occur after she hadn t gone for some time, but there seems to be more if she goes then tries again within the hour. She is showing no signs of discomfort, doesn t have a fever and is acting normal (playing, running around, etc). What could this be?
