5. Leyla Mafi (Age 9)
Leyla Mafi is definitely one of the strangest cases in our list of 11 youngest birth mothers of all time. She was prostituted by her own mother since the age of 8 and her clients were, among all, her own cousins. 11 years later, she was diagnosed with a mental disorder, that made her remain at the mental age of 8. At the age of 9, she gave birth to her first child and got twins 5 years later. As all of this wasn’t bizarre enough, she was sentenced to death at the age of 19 for debauchery, incest, and illegitimate motherhood. After the defense had made a statement, her sentence was reduced to public beating and prison.
