OK, this is what I did in about 2 min. I added contrast. I use PSE, so I upped it I think to 16. But you can't do that with white-whites in the shot or they blow out. So before I added contrast, I highlit the white whites on the shirts using the magic selector wand thingie and then chose "select...inverse" and then added contrast to everything but the white-whites.
Then I went to her face, generously selected her eyes and removed shadows AND added a litle more contrast. I did the same with baby.
If you convert to B&W, unless you add some contrast, you have too much bland greyscale for most shots. You need to up the contrast to add interest and to make skin not "wierd" looking.
I have no doubt better conversions can be done, but that's my 2-minute attempt.
