I like Crayons! Can I eat them?

Luke wants to do everything that Clare is doing.  So recently I offered Luke a crayon to color as well.  He enjoyed it for 5 seconds, then realized he forgot to put this new object in his mouth.  We went through this routine for 15 minutes.  We've colored a few times since his first introduction to crayons.  He is getting better with keeping crayons on the paper and not in the mouth.  Clare likes to remind him, "No crayons in the mouth, Luke.  Keep it on the paper.  See?  Watch me."
