Many newborns experience jaundice during the first week of life, however a paediatrician should evaluate the bilirubin level of a 6-day-old baby. Gardenal should only be used if a child specialist expressly recommends it and is not typically administered on a regular basis for typical infant jaundice. With proper nutrition and, if necessary, phototherapy (blue light treatment), most newborns get better. A newborn should never be given medication on your own since the incorrect dosage can be dangerous. Seek urgent medical care if the baby is very sleepy, not feeding well, has fever, or the yellow color is increasing.
