Chores for Sam?

So, it goes like this....I'm in the living room, folding laundry. Sam is playing. He wanders into the kitchen, which he does often, though he usually comes back because there's not much cool to play with in there. But this time, he doesn't come back. Instead, I hear a familar sound. I rush into the kitchen to find that Sam has gone into the laundry room (I guess I left the door open), scooped out a scoop of dog food from Oscar's bag, and then put it into Oscar's dish without dropping a single morsel. Oscar was happily enjoying an extra meal. Sam was proudly standing there, watching Oscar eat, and still holding the measuring scoop. Maybe it's time to assign this to Sam as his daily chore:-)
