While Joshua seriously studied his toys, he simply enjoyed tearing up paper towel with sheer delight. I used a piece of paper towel to wipe his mouth, then placed it on the piano. He is at the height that he can reach the piano cover, and he picked-up the paper towel. WOW! He started to tear it apart, and then uttered a giggle with sheer delight when he listened to the tearing sound. That certainly fascinated me too. So I giggled with him. That action seemed to qualified me as his buddy (or co-conspirator) in his mind. He gave me such wonderful smiles, later he took a nap on me comfortably. He woke up without looking at me as if I were a stranger. I think he felt that he can now confined in me after he and I have gone through the tearing up paper towel adventure together.
