When we went down to visit the Maternal Infant Care division we spent a lot of time talking about premature babies. These are the little guys you see in incubators at the hospital. (Before I continue let me say that I know almost nothing about babies. I don’t have one and spend very little time with them.)
Okay … So the thing that I found most interesting from the trip is why incubators exist (and specifically why GE has added some of the features they have to the products they make). So basically a premature baby is tiny, it was meant to spend some more time with it’s mother before it was ready to face the world on its own. Something happened and it wasn’t able to do that, so now all of a sudden it finds itself out of the womb, but it hasn’t yet developed to the point where it’s really ready to fend for itself.
So, part of the reason you put a baby like this in an incubator is to regulate it’s temperature for it. Basically, if the baby had to keep itself at 98.6 on its own it would waste a ton of energy. Because the incubator is doing the job the baby can focus those calories on other stuff, like growing. The same is true with moving a baby around: Every time you jostle a baby and they need to readjust themselves they waste those same valuable calories. 
Which is why GE added the Baby SusanTM to their Giraffe Omnibed (this is no joke, it’s really called the “baby susan” … see photo above). It does exactly what it sounds like, allowing nurses to get at babies without having to move them every time. Nice to see kitchen innovations making it into the hospital. In case you still want to learn more, here’s some of our GE hosts explaining this stuff:
