Question:
May one delay a bris milah after a child has recovered and is medically fit for circumcision, in order to arrange a larger celebration, accommodate guests, or for another non-medical reason?
Answer:
No. Once a child has fully recovered and is medically and halachically fit for a bris, it is forbidden to delay the circumcision even for a single day without a valid reason. The bris is to be performed at the earliest opportunity, and one may not postpone it due to convenience, scheduling considerations, or to increase attendance. Furthermore, for every day that a father leaves his son uncircumcised after the obligation of milah has taken effect, he neglects the positive commandment of circumcision. Accordingly, as soon as the child is deemed healthy enough for the bris, it should be performed without delay.
