Hermione must've blacked out several times from the instant the healers arrived. Afterwards, she seemed to remember very little about the birth. Or it was just a part of her brain that decided she shouldn't remember some parts.

But when the tiny wails could be heard in their bedroom, it was like something inflated inside Hermione's chest and everything made sense again.
