For some reason, I have it ingrained in me that a baby boy's name before the bris is a secret and should not be shared. Are there any sources for this, or is it something made up?

  • The time between birth and bris is considered a 'dangerous time' for the baby. A sick person can change their name to fool the Malach HaMavet, so perhaps not having a name at all could be considered a similar protection for the child. (no source) – zaq Sep 14 '11 at 19:38

    @yoel Were you told to do that only after you and your spouse decided on a name, or did even the planning/suggestion stages have to happen on paper? – Double AA Feb 26 '13 at 21:31

    @Ze'evFelsen Can you source that? – Double AA May 12 '14 at 20:15

I don't know of a halachic reason, but I can think of some good practical reasons. With naming after people being a way to memorialize family members who have passed on, different family members may have different ideas about which family member is most important to remember. You really don't want to go into a Simchah with In-laws fighting with each other and with you over which deceased relative was more worthy of being remembered. The custom that parents must decide the name, combined with the practice of not announcing the name in advance minimizes (although doesn't eliminate) lobbying and arguing and hence bad feelings.

Not announcing the name in advance also leaves the parents' options open to change their mind up to the time of the Bris. I've known parents who went back and forth over which name to choose right up to the time of the Bris. If you announce the name in advance it makes it much harder to change your mind.

  • Reminds me of the Chelm story of parents fighting ove which side to name the baby after. She wanted after her father (Moshe the horse thief) and he wanted after his father (Moshe the embezzler). The rabbi said, name him Moshe and we will see which side he takes after. I have heard of cases in which both sides pointed to a relative on its side that the baby was "obviously" named for. In actuality, the baby was named for a famous tzaddik (no relation). – sabbahillel Jun 10 '14 at 13:13

This is a good question which wasn't really answered in the last seven years. I found a number of sources

  • R Moshe Taub (here, part 1) quotes Rav Gedalia Shor, that we wait until a boy’s bris to give him his name, as opposed to a girl who typically receives her name before she is eight days old. Since until the bris the boy is somewhat incomplete, his purpose is also unclear. Once the bris is performed he is then ready for his name

  • Halachablog brings up sources in the Rishonim (Siddur Ri Ben Yakar). The reason being that it is only after the removal of the orlah (foreskin) that the baby is in his perfected state and prepared to receive his Jewish name (Chesed l’Avraham 2:52 from the kabbalistic master R Avraham Azulai)

  • R Eli Mansour writes the Sephardi custom is to follow the Sod, the opinion of Kabalistic teachings, and refrain from naming the baby until the time of the milah (Hishmat Abraham), even in cases the milah is delayed.

  • Tzitz Eliezer 18:54 brings these and other opinions, tracing what he calls "this holy minhag in Israel" to the times of the Second Temple

See here for more on the special case of a sick baby whose brit mila is delayed - where poskim are split whether to give the name before the brit mila or wait.

  • "to the times of the Second Temple" That's a cute way of referring to the New Testament (Luke 2:21) – Double AA May 15 '18 at 14:35
  • I can't tell if all of these sources are only talking about the epochal conferral of a name on the child, or including casual addressing or referring to the child by a given name. The question seems to be more about publicity of the name than either of these. Do any of them address casual (public) references explicitly? – WAF May 16 '18 at 20:39
  • @WAF I remember I read somewhere not to refer to the name even between father and mother but I don't think it appears in the sources above. I had seen others which I don't list. – mbloch May 16 '18 at 20:47
