Mishawaka police officer Bruce Faltynski and his wife, Shelby, added Myah to their family on Friday, which was National Adoption Day.
Myah was a newborn when she was surrendered earlier this year at a Safe Haven Baby Box in northwestern Indiana's Lake County. The baby boxes are named after the Indiana Safe Haven Law, which enables a person to give up an infant no more than 45 days old anonymously and without fear of arrest or prosecution.
"We are so grateful for Myah's birth mom. She made a really courageous decision," Shelby Faltynski told WNDU-TV.
In March, she and her husband finalized the adoption of their 8-year-old daughter, Kaia.
Weeks later, they received a call from Indiana's Department of Child Services informing them that another child -- the newborn the couple named Myah -- also needed a home.
After she was surrendered, Myah was admitted to a hospital's neonatal intensive care unit, where doctors determined she had suffered a stroke. But the Faltynskis say she is now doing well and is meeting all of her young milestones.
