Any more details on the shoot to help us out?
Inside, outside? Equipment? (I assume your pentax and maybe a flash?)
Outside, I would say find a shade and use fill flash.
Inside everything is going to be straight flash. A low sync speed (more abmient light) and bouncing or diffusing or multiple sources would improve the pictures. High speed film, but not too high.
The big advantage I see in this situation is that everything will happen in the same spot. This means you can set up and shoot ever kid exactly the same. Get your exposure and framing set and then your done. Just set the cameraon a tripod, talk to the kid and santa, click click... next.
With the tripod you can sync slower (1/30 or 1/20) before the motion of the kids sitting become too much. You will also have a chance to get the flash off camera.
Maybe a tripod is the wrong idea, but definitely try to get some more details about the conditions and what is expected of you for knowledgable people who will read this in the morning.
