" But instead here you are standing up, making the contractions back off, perhaps back to 30 to 35 seconds. But they’re coming closer, so you think standing is making things go faster, but remember, it is the long, strong contractions that get your work done and open that cervix. If lying down brings on longer, stronger contractions and you’re getting up to get away from them, then you may be defeating yourself. Standing up may trigger closer contractions but frequently makes for shorter contractions "
