 The location of the gathering is determined by where the father of the new baby spends Shabbat, since he presides over the event.Thus, a Shalom Zachar usually takes place in the home of the newborn (even if the newborn is still in the hospital), although it may also take place at the home of grandparents, in-laws, or even friends with whom the father is spending Shabbat.Typically, mainly men and boys drop by to convey their congratulations, to have a bite to eat, to share words of Torah, and to sing songs welcoming the newborn and thanking God for the birth.
