Infant with neonatal jaundice after birth is very common. Normal jaundice in healthy infants is called "physiological jaundice". Physiological jaundice usually starts the day after the birth and reaches the highest levels in 3rd and 4th days and gradually diminishes. Yellow colour on the skin and sclera of the baby is remarkable. Jaundice, usually on 2nd-3rd days, starts on the face and steadily spreads to the down parts of the body. Frequent breastfeeding in this period is useful. Neonatal jaundice is not a contagious disease. The baby should be examined by the doctor within the first 3-5 days. If neonatal physiological jaundice is not healed within 1 month, liver analyses should be performed.
