Feeling a little blue? Sonia will help cheer you up with this video:
If you're curious to know what I was doing to make her laugh so hard, you're going to be disappointed (unless you have the same sense of humor as a seven month old baby). I was putting something on my head and letting it fall off, over and over and over. That's it. No silly faces, no silly noises, nothing. She also laughed when I did the same thing to her Ernie doll-- I put a little hat on him and let it fall off, and she laughed like a hyena. Goofball!
