Hello i have noted your concern, neonatal jaundice if it is physiological, it will be self limiting no treatment is required and usually ends by 2-3weeks in term babies, but if jaundice persists more than 3weeks it is always pathological and there must be some ongoing abnormalities going inside the body.
Next Steps
kindly visit pediatrician once for proper evaluation treatment and management.
Health Tips
do not self medicate or try any home remedies
if it left untreated, worsening of jaundice might effect the brain of the baby, so do not neglect of there is no improvement in the condition.
