Do hospitals use any painkillers for labor?

And if they don't why not? I don't think they do cause then they wouldn't feel the pain right? But there's always pain during labor, at least last time I heard of it there was, maybe now they use morphine and shit but I don't believe they do, I think labor is still the same as its been for centuries, if the baby is coming out already, the baby won't be in the mother long enough for the painkiller drugs to do any harm right? morphine kicks in within seconds, if they start pushing then the baby shouldn't get effected by it right šŸ™ƒ
