Yay .jenny! Their first laughs are so precious! I remember when .adriana did it, I had her on my bed while I folded laundry, and every couple of minutes I'd go play with her, and I was standing over her and I'd look down and put my hands on either side of her and go "boo!" and she laughed! I called my mom so she could hear it, but of course she wouldn't do it when I was on the phone lol.
I agree, you need to get that on video so we can all see her beautiful little self!
