How long is a normal hospital stay after having baby natural?

My SIL only stayed one night. With my son Induced because of preeclampsia and my son had jaundice. So we stayed a week. So I don't know if one night is normal? Trying to see what to expect if I have a natural birth this time. 25 weeks with my second boy.
