I can understand your concern.
You cannot do anything at home to prevent newborn jaundice.
baby's liver cannot handle the load so it gives rise to new born jaundice,
just take him to a pediatrician and he will take care of the child.
by the way, i want to know what kind of supplements are you talking about?
and also whose medicines have you mentioned here?
please make some sense from next time onwards.
