Yes.
as per our pedia po
if breastfed, up to 1week
if formula fed, up to 4days lang.
as long as di iritable o matigas ang tyan ni baby..
also, always do tummy massage at yung bicycle kicks exercise, leg rotation kay baby atleast 2x a day to help sa tummy nya.
if after a week or kahit 4days at wala pa ring poop, best is to consult your pedia na.
