Oh Grasshopper

Cole has this new obsesssion with bugs! He will find them just about anywhere and pick them up and bring them to me to see, *lovely*! So on this particular morning, the older kids had pointed out a few grasshoppers to him. He chased several around for a while until this poor grasshopper didn't hop fast enough. He loved picking it up, staring at it, and showing me! In the end, the poor grasshopper met his death, Cole just pinched him on the neck and basically popped his head off :( Any ideas on how to teach an almost 2 year old boy how to be gentle with bugs? Advice appreciated!
