I have a relative who cannot conceive, and she adopted a daughter from an orphanage. She went to the doctor, who gave her an injection, and she started producing milk. She breastfed the girl; does this make her her daughter and her husband's daughter through this milk? Has he become her father? What is the ruling when the girl grows up? Is she considered his daughter and does she need to observe hijab from him? Has she become his stepdaughter after his wife breastfed her?
