A couple of recent news stories have highlighted the way that science, society, and the legal system are changing the definition of what it means to be a family. Just ask Natasha Bakht and Lynda Collins. Ms. Bakht and gave birth to her son, Elaan, seven years ago after using a sperm donor to get pregnant. From the moment Elaan was born, Ms. Collins was there for the family, eating meals, attending appointments, even joining them on holidays. Both women felt Ms. Collins had become a second momma to Elaan. But since they were not a romantic couple, it was not easy to for Ms. Collins to become Elaan’s adoptive parent.
