How is pathological jaundice treated in a child who gets sick three days after birth?

Patient's question:

Patient Age: Newborn
Condition Description: Pathological jaundice for 1 day, currently doing well, but with slightly elevated bilirubin. Past Treatment and Effect: Under treatment, still unsure of the current condition.
Desired Help: Would like to ask if there are better treatment methods available.

Doctor's answer:

Hello, most newborns develop jaundice 2-3 days after birth, with it being most pronounced on days 4-5. Full-term infants typically recover within 10-14 days, while premature infants may take 3-4 weeks to clear. Pathological jaundice often appears within 24 hours of birth and lasts for more than 2 weeks, with premature infants experiencing it for more than 3 weeks. Your baby has newborn jaundice, which is mostly physiological and may gradually fade over time. If the jaundice worsens further, phototherapy (blue light) can be administered, and in necessary cases, a blood exchange may be performed to help the jaundice clear more quickly.
