If you've spotted mucus in your little one's diaper, here's what it might mean – and when to check in with a doctor.

Possible reasons for rectal discharge or leakage of stool include an infection, cancer, rectal prolapse, an abscess, a fistula, or hemorrhoids. A person may notice mucus in their stool.

When blood from your nasal lining dries, it can mix with the mucus and turn brown. But brown mucus isn’t always because of blood. It could also be dirt, dust, or discolouration from inhaling smoke.
