Hello my kid is 2 year 6 month old or Abhi ham Finland me hai last 2 days se mera beta black potty kar raha hai is this normal?

A. Active black colour motion is very common to be seen if you’re giving any kind of iron supplement to the child then you will see that it will happen to anybody whether it is a child or an adult and sometimes it could be due to the kind of food that you are giving like a dominant colour and the food can also change the motion colour
