A child passing black stool may be due to consuming foods such as pig liver or duck blood, or caused by taking iron-containing medications, which are usually normal and will return to normal after a period of time. Additionally, if a child has conditions such as portal hypertension or gastric ulcers, gastrointestinal bleeding may occur, leading to black stools.
