This is something that always confused me since I first read the book.

"About twelve o’clock that night was born the Catherine you saw at Wuthering Heights: a puny, seven-months’ child..."

I still wonder how a baby born at only seven months would survive and thrive, especially since I doubt neonatal care was that great in the 18th century. Is it possible Nelly miscalculated how far along Cathy's pregnancy was or that the second Catherine was just lucky?
