My NB has jaundice and i have heard breastfeeding causes the jaundice level to rise is it true? Any mummy can advice how to reduce the jaundice level?

my PD advised me to ensure baby is feeding well in order to produce wet diapers (to flush out the jaundice). he mentioned that if the bm is insufficient, it might be good to top up with formula to ensure baby drinks sufficiently in order to have good output.
