Debbie:
Welcome to RetouchPRO. I wish the circumstances that inspired your post didn't pull at my heart like they do.
Before I forget, this site is packed with
PSE tips if you haven't found it yet:

As time goes along you'll discover there are sometimes numerous ways to solve a given problem. This is a classic example.
I used a method similar to what Paulie advised. First I added a Hue/Saturation adjustment layer (click the add adjustment layer icon [1/2-filled in circle] at the bottom of the Layers Palette). Drag the Saturation slider to the right a bit. This will mess up everything else color-wise, temporarily. Don't worry about that for the time being.
Now, CTRL + I (to invert) the H/S layer, undoing the H/S effect.
Set your foreground color to white and choose the brush tool. Turn on the airbrush setting (see
http://www.arraich.com/elements/ref/tool_airbrush.htm).
Opacity ~ 50% and flow ~ 50%, start airbrushing on her skin areas, which will selectively reveal the effects of the H/S adjustment layer. Adjust brush opacity/flow if needed. Switch to black and airbrush any areas where you "over did it."
Because some of the areas are nearly 50% gray (neutral), the H/S adjustments won't affect them. So then I added a layer per Paulie's suggestion (blend mode = color) and airbrushed a little skin color in areas I thought needed it.
One way to get decent skin color (and your brush tool has to be the active tool) is while holding down the ALT key (your brush will temporarily turn into the Eyedropper color sampler tool) click on an area of skin that has some color. Doesn't have to be Susie's skin... could be anyone in the image. This will populate the foreground color, which I used to airbrush in
My prayers are with you and your family. Hope this gets you moving.
