"Right! Thing!" Sirius slapped his forehead and then rushed back over to Remus' side, wrapping an arm around him and getting distracted again, just looking at Draco. "Such a cute boy! The best boy. You are the best boy, Harry, did you know?"

Harry didn't know, but he did gurgle. And tried to go for the hair again.

"THING!" Sirius remembered once more, reaching into his pocket and retrieving a wrapped up little present. He enlarged it to its proper size and then handed it over to Harry, smiling at him. "You can open it."

He could not. But he could chew on the wrapping paper beautifully. Which delighted Sirius. "Look! His mouth is red." Brilliant stuff.
