This is Lina Medina, the youngest 5 year old mother in history, 1939
Lina Medina was born in Ticrapo, Peru and became the youngest confirmed mother in medical history. At the age of 5, she delivered a son that grew up with her thinking she was his sister. At the age of 10, he found out that Medina was his mother. He died at the age of 40 and Medina is still alive but refuses to give any interviews.
As might be expected, sexual abuse was immediately considered as the reason for her pregnancy. The father of Lina was arrested on suspicion of rape and incest but was released due to lack of evidence. Lina Medina never revealed who the real father of her child is, or the circumstances surrounding its impregnation.
