Ben's favorite thing to "help" with is unloading the dishwasher. In efforts to keep the items clean, I always sacrifice one or two items to his cause (usually a ladle or spatula) and then rush to empty the racks as fast as I can.
This time I handed him the garlic press. As I turned away I thought, "I'd better take that back before he pinches his fingers in it". However, I turned back around to find him expertly crushing his little freeze-dried yogurt snacks at the counter. He had no difficulty knowing what to do with it and how to open and close it effectively; and without harming his capable little pinkies. He had a great time rubbing the resultant snack powder all over the counter too.
