Re: I need sleep
SIDS really is rare. It just happens to be more common than the other causes of mortality- in the developed world, at least, where most babies survive infancy. In the less developed parts of the world, you'd be way more worried about diarrhea than about SIDS.
No-one knows what causes SIDS. It seems like the leading hypothesis is some sort of physical abnormality in brain function that can cause a baby to stop breathing or prevent a baby from rousing from sleep when she is in physical discomfort/peril. There's not much you can do about your baby's brain function, if that's the root of SIDS- but there's a lot you can do about the environmental factors that are associated with increased risk of SIDS. Like making sure your baby sleeps on her back, not smoking, getting adequate prenatal care, and sharing a room with your baby at night.
Side-lying nursing doesn't mean that the baby sleeps side-lying, too. Ideally, you nurse, and then when baby unlatches you gently roll him back onto his back.
