The first stool passed after birth is thick & black & ''tarry''. This is the Meconium. The frequency and appearance of the stool thereafter may vary from newborn to newborn and may change with changes in diet.
The Breast fed child usually has soft ''grainy'' stools ------looks like mustard seeds or finely scrambled eggs. (sorry about the analogy).
Strangely, some breast-fed kids may have 6,7,8 stools per day, while some may go 6,7,8 days without a stool!!
Stool appearance or frequency becomes important when there is a change from the norm without a corresponding change in diet, or when it is associated with other symptoms such as regurgitation of feed, fever, lethargy, reduction in appetite.
