Newborns experience a physiological jaundice period after birth, which is normal after treatment. Jaundice can be severe throughout the month, but it’s not particularly severe. It may be related to breastfeeding. There’s no need to worry, and it won’t cause intelligence issues. The value of pediatric jaundice is not high, and breastfeeding is good as long as the mental state is good. Generally, there won’t be bilirubin encephalopathy if the baby is born without conditions like oxygen deficiency, asphyxia, or pneumonia.
