Aw babe, alam ko yan ang worry mo, honestly green poop can be normal lalo na kung exclusive breastfeeding pa, pero since it's been 4 days at pakonti-konti na ngayon, it's better to check with your pediatrician or kahit sa midwife ninyo para ma-assess nang proper. A few of us moms dito sa community had similar concerns at lagi ang advice ay mas okay mag-consult na lang kasi every baby's different, at only a doc can tell kung may feeding issue or something else going on based sa overall behavior niya (if active pa, feeding well, may wet diapers).
