If a woman gives birth to a second son naturally when the first son was born by caesarean section, that child is not redeemed either. Additionally, a first-born male does not require redemption if his birth was preceded by an earlier miscarriage by the mother that occurred after the third month of pregnancy. However, if the miscarriage occurred during the first 40 days of pregnancy, redemption is required. If the previous miscarriage occurred after forty days, but before the fetus developed distinguishing characteristics, redemption of the first-born is still required, but the blessing said by the father is omitted.
