Hi new mom, newborn jaundice is common. Expose your little one to early morning sunlight for VIT. Mild infant jaundice often disappears on its own within two or three weeks. For moderate or severe jaundice, your baby may need to stay longer in the newborn nursery or be readmitted to the hospital. Treatments to lower the level of bilirubin in your baby's blood may include: Enhanced nutrition. I hope this helps.
