  • The premature birth before 37 weeks of gestation and this type of jaundice recovers normally within 3 weeks.
  • Different blood types of mother and infant that cause antibodies formation lead to breakdown of Rbcs.
  • Non breastfeeding or inadequate amount of breastfeeding.
  • If the infant got a bruise during birth.
  • Viral infection.
  • Hereditary liver diseases or diseases that cause breakdown of red blood cells.

Causes of jaundice in older children:
