Z is driving me crazy with his grabby hands. He squeezes my arms and my belly fat all the time. While it is good motivation to get to the gym, it really is inappropriate behavior, and he is starting to do it to other people. When he and his brother are jumping on the trampoline, he'll stand behind him, put his hands around his neck, and squeeze. Again, something he should not be doing. Any idea on how to discipline for this? I'd love to do some positive behavior methods, but I am at a loss on how to do it for this issue.
