my baby is 2 month 10 days he is passing stool in green color from last Sunday why it is and is it normal or any issues ?

A. Actually, green poop is common in both breastfed and formula-fed babies, but it's more common in formula-fed babies. While breastfed babies tend to have poop that's yellowish (and sometimes slightly greenish), formula-fed babies have poop that's more brown: usually tan, yellow/brown, or green/brown.
