My baby of 1 week old always poo during or after eating. She is on breastfeeding n supplement. Her poo is yellowish and kind of watery. Am worried.

There is no need to worry as long as the stools are normal and not watery (watery stool are those that sink into the diaper)

Ma'am, supplement are not necessary, at 0- 6 months baby need only exclusively breastfeeding.
