Koivu loves to play with his sister. His favorite game is to jump up and pull the blanket and pillow off the couch if I'm not looking. If I go into another room to get something, my blanket and pillow will be on their dog pillow when I return to the room. He doesn't like to let me out of his sight. Needless to say, I haven't been able to get a lot of work done unless they are sleeping. Koivu loves his stuffed duckie that quacks when he chews on it. He's all around a sweet boy.
