Recently they added a UV light that is a strong blue color. They said that because her kidneys/liver aren't fully developed, this light will hit her skin and help break down things in her blood similar to how a kidney/liver would. A number of other babies in the ICU had this, so it's fairly common. As you can see from the picture below, it kind of looks like a bug zapper.
It also messes with your eyes. Once you stare at the blue light for a long time and then look up, everything looks orange for about 30 seconds. You'll see our daughter with a mask over her eyes to prevent her from getting agitated by the strong light. I had to convert this picture below to black and white so it wouldn't be so blue. Next to her left hand is my ring.
