Will neonatal jaundice reappear after blue light therapy?

My child was premature and spent a significant amount of time in the hospital. After discharge, I noticed that the jaundice has started to recur. I want to know if neonatal jaundice is prone to recurrence?

Will the jaundice in children with sickle cell disease come and go?

Newborn jaundice may increase, especially pathological jaundice, which requires timely treatment.

The normal range of newborn jaundice is based on the reference of serum bilirubin levels, with full-term infants not exceeding 204μmol/L (12mg/dl) and premature infants not exceeding 255μmol/L (15mg/dl) considered normal. Additionally, children with physiological jaundice, apart from skin yellowing, have little impact on appetite and spirits, and the symptoms usually resolve automatically within a month.
