my baby is 4 and half month her poop is dark grey(ash) colour from some days i am giving iron drops as per pediatrician recommendation.. she is on both breast and formula feed.. is ti normal please tell me

A. That is because of the formula feeding that you are giving to the child as well agile any time having formula can lead to the motion colour dark green to green and that is considered very normal and common currently it’s because of the milk that you are doing
