An Update on the Cups

Today Alison was running all over the house with her cup of milk. Camlyn was in hot pursuit of her and a cup in his hand. I stopped him and told him that if he took her cup, I would take his. He looked at me, smiled, gave me his cup and took off after Alison. Stinker! He might not speak much but he does understand! Any ideas on ending the cup war would be appreciated.
