Is it true that Jewish parents aren't supposed to name their children after their own parents?
Some Jewish people do name their babies after a relative who is still alive, but many Jewish people follow the tradition of not naming a child after a living relative, particularly those relatives who are young. This means that you rarely find Jewish children named after their own parents.
Traditions and customs form an important part of Jewish life and this depends on your family beliefs and practices. When it comes to baby naming, Ashkenazi tradition is almost entirely to name the baby only after a relative who has already died, while some Sephardic traditions allow for naming the baby after an elder relative. Generally speaking however, no Jewish tradition supports naming the baby after their own living parents.
