[|AI|]  one-week-old baby who is dependent on milk diet only usually have this kind of stool pattern. This is called transitional stools. Initially baby passes greenish black stool then greener than yellowish green then by day 6 or 7 yellow bright goldens. After birth the flora (healthy bacteria) of babies gut start to develop which causes this change in stool color, after 7 to 10 days stool will remain like this.nothing to worry. Please try to give breastfeed as much as possible. Exclusive breastfeeding is best. Formula feed has nothing to do with this change in color.
