Just given my four year old daughter a bath and noticed light blood satins in her pants - looks like spotting in a menstruating woman. But she's only four! She claims to have no pain when weeing or pooing so I don't think she has cystitis or an anal fissure ( which she did have when she was two - the fissure, I mean - so I think I would know about that). Couldn't tell when I examined her down below where the blood may have come from. She is fine in herself. Anyone got any experience of this?
