SEIF 2
Women, like men, are obligated in the Mitzva of Kiddush. Even though it's a Mitzva Asei SheHazman Grama (a positive Mitzva that only applies at certain times), from which women are usually exempt, however, since Hashem said the Mitzva of Kiddush and the Mitzva of keeping Shabbos at the same time, it teaches us that everyone who is obligated to keep Shabbos must also make Kiddush. Since women are obligated to keep Shabbos, they are also obligated in Kiddush.
