What to do with missing body parts

[JTanksley]

I just started on this photo and now I've come to a part where I don't know what to do with the hands and feet. Here are the Before and afters. I think I could make a nice crop but i'm not sure if cropping was allowed.

Thanks!!

This is the blue channel after levels. The mother's left hand shows up a little better. I cropped a little off. I'm assuming this is an 8x10?
