Humanistic Judaism offers alternative methods for welcoming new baby boys and girls into their family and as members of the Jewish people:
Brit Shalom is a ceremony designed for male Jewish babies who are not
circumcised. It can be scheduled either for the 8th day following birth, or
another date that is more convenient for the family.
Simchat Bat is a ceremony designed to welcome a baby girl into her family
and as a member of the Jewish people.
Simchat Ben is a ceremony designed for a baby boy who has
been non-ritually circumcised (i.e. by a doctor) to be welcomed into the family and as a
member of the Jewish people.
