The battle of the sippy cup

I'm desparately trying to get Reese to drink from a sippy cup. We are now on our fifth different type of cup, and still no luck. Today, we may have had a breakthrough. Rather than tossing the cup on the floor or screaming at the sight of the cup, Reese actually touched it, picked it up, took one sip, and put it back down. That's all. No screaming, no cup on the floor. I have hope.
