The 76th mitzvah is that every woman who gives birth is required to bring an offering; a yearling sheep as a burnt-offering and a dove or young pigeon as a sin-offering. If she is poor, she brings two doves or two pigeons — one as a burnt-offering and one as a sin-offering.
Her atonement is also1 considered to be incomplete until she brings her offerings, as it is written,2 "When her purification period for a son or a daughter is complete, she shall bring a yearling sheep...[the kohen shall then make atonement for her and she shall be pure]."
