In the Torah it says that Hashem changed Avraham’s (Abraham) name from Avram to Avraham at the time of his circumcision. In keeping with that tradition, a Jewish boy is given his Hebrew name at the time of his Bris Milah. Judaism places a great deal of significance on a child’s Hebrew name.
A Hebrew name is a gift which lasts a lifetime. It is a symbol of Jewish identity and a banner your child will honor and cherish, linking him to his family heritage. It is often customary to name the child after someone who led a righteous life so that the child will try to emulate that individual. Ashkenazi Jews often name their children after a dearly departed relative, while Sephardic Jews sometimes name their children in honor of living relatives. In the case of someone who died at a young age, another name referring to life, or the name of a person who lived a full life is added. Consulting with your Rabbi or spiritual advisor is always commendable with regard to your customs.
WHEN TO DELAY A BRIS MILAH
A Bris Milah is never performed if it poses any danger to the infant. The doctor and/or mohel’s advice to delay a Bris for health reasons should always be heeded. In case of jaundice (yellow pigmentation of the skin), the bris cannot be performed; it is delayed until the bilirubin in the blood drops to a safe level. The bris may then be performed without endangering the child. In cases of some illnesses, a delay of seven days following full recovery is required. It is forbidden to postpone the bris for any reason other than health of the child, or in order to obtain a proper Mohel. It is the responsibility of the Mohel, in consultation with the doctor and the family, to determine if a delay is necessary according to Jewish law.
