Children Children under the age of Bar and Bat Mitzvah are generally included in the lighter mourning practices as training for mitzvah-observance. Thus, they will also refrain from listening to music or getting haircuts during the entire Three Weeks. However, young children are allowed to wear freshly washed clothes, and parents are allowed to launder those clothes for their children during the Nine Days. The Nine Days typically coincide with summer camps for Jewish children in America. While swimming and water sports are avoided, camps often run special study programs and Holocaust education modules. On Tisha B'Av itself, campers gather to listen to the traditional reading of the Book of Lamentations and engage in creative projects that express the themes of the day. Exceptions On Shabbat, all forms of mourning are suspended. Therefore, observant Jews eat meat at their Shabbat meals and drink wine or grape juice for Kiddush as usual. Similarly, while during the rest of the week one cannot wear freshly laundered clothes, on Shabbat, this is allowed. Throughout the Nine Days (excluding Tisha B'Av), guests at a seudat mitzvah — for example, a brit milah ceremony, a pidyon haben, a bar mitzvah seudah on the boy's birthday, or a siyum — are allowed to eat meat and drink wine. Some yeshivas, kollels, and other study programs try to plan the completion of a volume of Talmud or Mishnah to coincide with the Nine Days so that a meat meal may be served. The last Lubavitcher Rebbe, Rabbi Menachem Mendel Schneersohn, requested that a siyum of a Talmudic tractate should be held every day of The Nine Days. Chabad now broadcasts the completion of tractates on its website. An exception to the prohibition against new construction is made in the case of a building constructed for a mitzvah. Thus, a synagogue, yeshiva or mikveh may be constructed or decorated during the Nine Days. Shabbat Chazon During each of the three Shabbats of the Three Weeks, a different Haftarah is read in the synagogue after the Torah reading. These are: Divrei Yirmiyahu (from the Book of Jeremiah 1.1-2.3) (In most years, this coincides with Pinechas. In leap years when the preceding Rosh Hashanah was a Thursday [or, in Israel, when the following Rosh Hashanah is a Monday], it coincides with Matot.) Shim`u D'var Hashem (from the Book of Jeremiah 2.4-28) (In the leap years stated above when Matot is
