Uhhhhh they'll marry young but they typically don't birth preteen-young (not saying there weren't cases, just it's not the norm...).
People usually died during child birth for other reasons (like hygiene and infection), and not because of body devolopment. Even smaller bodies can give birth safely, the baby just ends up suiting the size of its mother (doctor verifiable).

In ancient times at 13 your an adult its 18 now what we know now even compared to 20 or 30 yrs ago our whom aren't stable during our teen yrs . And I don't think theres a guy in existance in any era that will wait. Back than a girls only reason for existing was to bare sons cause daughters cant inherit that was there reason for polygamy.
So youre telling me all these guys having feelings for or are at least 20 or over 20 and shes 10 and it doesnt stop at 20...theyre even over 1,000 Of ageΣ(  ̄□ ̄||)
