You can bring to baby to check his jaundice level at polyclinic every alternate days if you are worry. If serum bilirubin level over 255 μmol/l (15 mg/dL), polyclinic will refer you to the hospital for phototheraphy treatment. If if is below the limit, you don't have to worry. For breastfeed baby the level tends to drop slower.
My no.1 took 2 months to totally clear the jaundice because it was due to breastfeeding jaundice. PD ordered a liver test for her to make sure there is nothing wrong with the liver.http://sg.theasianparent.com/help-my-baby-has-jaundice/
