I wish I could get pics of mine playing like that, but as soon as the flash goes off on my camera, Emily stops.
I sort of have the same problem as far as getting pictures of my two playing. As soon as I reach over to pick up the camera, they both stop what they are doing to watch me .

I am hoping if I just keep picking up the camera it will become so ordinary that they ignore it but it is tough, they both tend to become instantly alert as soon as I move.
