my baby is 3 month now but from 1 month her potty colour is green and grey mix so is it normal or any problem pls help me she is on formula milk

A. it's normal.. no need to worry about it..! imbalance of foremilk/hindmilk, often resulting in frothy green stools. .It Can be remedied by limiting feeding times or sticking to one breast when feeding your baby. If your baby is on formual milk then it is also normal . Certain brands of formula milk resulting in green poop.
