The Bris of a healthy baby is done on the eighth day of life (counting the day of birth). This is so even if the eighth day falls on Shabbos, Yom Kippur, or any other Jewish festival. However, in the case of a baby born by Caesarean section, the Bris is not performed on Sabbath or a festival but the day following. Bris Milah may not be completed before the eighth day or at night. If a baby is not in perfect health — even if not seriously ill — the Bris is delayed until both the doctor and the Mohel agree as to the nutritional status of the baby. A typical example of this situation is newborn jaundice. However, a delay of one week following full recovery is required in the case of serious illness.
