Culturally, the Sundanese people adopt a bilateral kinship system, with male and female descent are of equal importance. In Sundanese families, the important rituals revolved around life cycles, from birth to death, adopting many of the previous Animist and Hindu-Buddhist, as well as Islamic traditions. For example, during the seventh month of a pregnancy, there is a prenatal ritual called "Nujuh Bulanan" (identical to Naloni Mitoni in Javanese tradition) which traces its origins to Hindu ritual. Shortly after the birth of a baby, a ritual called "Akekahan" (from Arabic word: Aqiqah) is performed; an Islamic tradition in which the parents slaughter a goat for a baby girl or two goats for a baby boy, the meat later being cooked and distributed to relatives and neighbours. The circumcision ceremony is performed on pre-pubescent boys and celebrated with Sisingaan (lion) dance.
