Today some fellows showed me an incredible Wikipedia entry. Yes, weird world. Lina Medina, a Peruvian child, is the youngest confirmed mother in medical history as well. She gave birth at the age of 5 years, 7 months and 21 days, which means at four she already got pregnant!
Apparently, "her menarche had occurred at 8 months of age (or 2 1/2 according to a different article), and that she had had prominent breast development by the age of 4. By age 5 her figure displayed pelvic widening and advanced bone maturation" (in Wikipedia). The curiousest thing is that nobody knows who is the dad of that children. Her father is the main suspect but he never condemned due to the lack of evidences.
Anyway, by curiosity I took a look at the list of youngest birth mothers and realised the fact is that the three first children on the list are all from Peru. Worst part: they were raped...
Still should I say, impressive!
