Katie Likes Her Pampers Swaddlers Box

A couple weeks ago, Wife put a box of Pampers Swaddlers next to the changing table. Ever since then, whenever Katie gets changed, she turns hear head and stares at the side of the box. The box is yellow with some teal and a picture of a mother holding a small baby. Whenever Katie stares at the side of the box, she immediately starts laughing and cooing. She could be hysterical, but the moment she looks over at that box, she is happy as a lark, smiling and trying to talk to the box. Why? I have no idea. Does she like the picture of the baby? Maybe, but the picture is upside down from her angle and seems like it would be hard to see. Could it be that Katie's favorite color is yellow? I started thinking that and started putting other yellow things in front of her, but those other objects get no reaction from her. I have absolutely no idea why Katie loves this box so much, but it is the most adorable thing to watch ever. Wife wants to get a video camera just so we could post a picture of Katie trying to talk to her box.
