This picture is from an article called "The Rescuing Hug". The article details the first week of life of a set of twins. Each were in their respective incubators and one was not expected to live. A hospital nurse fought against the hospital rules and placed the babies in one incubator. When they were placed together, the healthier of the two, threw an arm over her sister in an endearing embrace.
The smaller baby's heart stabilized and temperature rose to normal.
