Not really after the fact. The large feet are caused by perspective distortion. Basically objects closer to the camera appear bigger. You can't really fix that as it is a consequence of physics. Sometimes when the feet are at the edge of the image you might be able to dial in some barrel distortion (in the lens correction panel in Develop, go to manual and slide the distortion slider to the left. This enlarges the central portion of the image with respect to the outside. However, generally the way to avoid this is to shoot the image with a long (i.e. tele) lens from a larger distance. This takes you as a photographer further away from your subject (the grandkids) and decreases the perspective distortion. This is in fact what most portrait photographers will do to avoid too large noses, too long limbs, etc.

This is a common effect with wide-angle lenses.
There is no fix after the photo is taken.
As Jao mentions, the only way to fix this is to change lenses before the picture is taken.
I appreciate the answers. I guess my only other alternative is to crop the feet out, but that does sacrifice some of the appeal.. I always did learn best through the school of hard knocks.
If you have Photoshop, you could try the Liquefy filter or the warp filter to try to make the feet smaller.
I doubt my skills at that would get good results.
