It is good and proper to have a celebration for a Bat Mitzvah in the same way that is done for a Bar Mitzvah - to invite family, friends and acquaintances and have them participate in the celebration. At this occasion, the Bat Mitzvah girl should recite the Shehechiyanu blessing over a new garment and - if she is learned - she should say words relating to the day, read the Song of Devorah and the first two verses of Channah's prayer.1See Ben Ish Chai, Year 1, Parashat Reeh 17; Shut Yaskil Avdi vol. 8, Orach Chaim 17; Netivei Am 225 at the end; Shut Iggerot Moshe, vol. 1, Orach Chaim 104; Shut Yabeah Omer vol. 6, Orach Chaim 29:4. The Song of Devorah is Judges 5, [the mentioned verses of] Channah's prayer are I Samuel 2:1-2. And the father of the girl should recite the blessing of exemption from the punishment of this one (exempting a parent from responsibility when their child becomes an adult).2See Rama, Orach Chaim 225:72; Kaf HaChaim, Orach Chaim 225:15-16. And they should bless her and say to her, "Our sister, may you become thousands of myriads."3Genesis 24:60. And she should, of course, go beforehand to the synagogue to pray, but not to go up to the Torah.
