We were drawn to this endearing picture of these wee, snuggling preemies in an incubator, and then read the story that came with it.  Here it is:
In the first week of life for this set of twins, each was in her respective incubator. One was not expected to survive.

A hospital nurse (with a brain and a heart) defied hospital rules and placed the babies together in the same incubator. (Hello-o!  Isn’t this what they’re used to?) When they were put together, the healthier of the two managed to put an arm over her sister in a sweet embrace.  

Not long after, the smaller baby's heart rate stabilized and her temperature rose to normal.

Something tells me these sisters will be very close, growing up… don’t you think?
