The Cause Of Feces For An 11 Month Old Baby Is Black?
Black children's feces can be caused by:
Coloring the child's food before
Medicines consumed, for example: supplements added blood, iron
The process of bleeding in the stomach
In conditions where the child is in good condition and no other symptoms appear, then you should not worry first, but still monitor the development of the baby's stool, you can even bring a stool sample to be examined in the laboratory.
Black will appear normally if your child's food / drink is previously dark or if your child is taking supplements with iron. This does not require special handling and will disappear by itself. But in other conditions, it can be dangerous if not handled properly.
Give children drink more often
Avoid dark foods / drinks
Avoid temporary use of iron supplements
See a doctor
