I had another thought about this today. You can try what we had to do for so many things: do it ABA style! Put your hand over his hand and go through every motion with him. Get him to get the paper, crumple it up while physically guiding his hand. Repeat as often as it takes, decreasing the amount of pressure you put on his hand till he does it on his own. Don't talk about it, just do it matter-of-factly. Kate
