Bilirubin levels are usually the highest when the baby is 3 to 5 days old. At a minimum, babies should be checked for jaundice every 8 to 12 hours in the first 48 hours of life and again before 5 days of age.
If bilirubin levels are high, substances formed when bile is broken down may accumulate, causing itching all over the body. But jaundice itself causes few other symptoms in adults.
