Stacey Herald is 35 years old, just 2ft 4in tall and already has two children.
She suffers from Osteogenesis Imperfecta, which causes brittle bones and underdeveloped lungs.
She lives with her husband and two kids in Dry Ridge, Kentucky.
And Stacey is pregnant once again. Amazing.
Her first daughter was born in 2006 weighing just 2lbs and 1oz.
After 28 weeks, doctors performed a cesarean section.
The second daughter was born after 34 weeks of pregnancy.
Now both girls are taller then their mother.
