Determining if a child’s mother’s blood type is O. Whether a child’s jaundice is slow to recede depends on the specific circumstances. First, the slow receding situation, if the child’s blood type does not match the mother’s blood type, this will often cause the child to develop hemolytic jaundice, thus causing the jaundice to take much longer to recede. Second, it does not cause the jaundice to recede slowly in children. If the child’s blood type is also O and is the same as the mother’s blood type, this will not cause the child to develop hemolytic jaundice. The jaundice in children is just ordinary physiological jaundice, and the jaundice remission time is not much different from that of children of the same age.
