This might be a stupid question...

I’ve never had kids (obviously, based on the question) but I was wondering.. after you give birth at the hospital or birthing center and it’s time to go home, do you put your baby in a car seat? Like an infant car seat? Or are you supposed to hold them? (while someone else drives of course). They just seem so small and fragile, like you would want to hold them. But I assume you’d use a car seat.
