Is "pasa" the same as bigkis? If yes, I would advice against it. Even hospitals do. According to my baby's pedia, the goal is to dry umbilical cord stump but with "pasa" or "bigkis", moisture is actually trapped which is why it's not recommended.
Our pediatrician advised not to use "pasa" para daw mahanginan yung pusod at hindi magmoist.
