The girls had an epic wrestling match on an air mattress, which was HYSTERICAL to watch. At one point Isa flung herself head-first off the side. Rather than bursting into tears, as I expected, given her faceplant in the carpet, she was laughing like crazy. They also spent a fair bit of time during the weekend talking to each other. I have really fond memories of playing with my cousins at the picnic every year and I'm glad she's going to get the same experience.
On an entirely unrelated note, tonight (as I typed this entry) is the first time that Isa has fussed herself to sleep. Normally, if she doesn't fall asleep right after I leave, she fusses. The fussing has always escalated to real crying, which is when I go in and try to calm her. I kept hoping that someday she'd figure out to just stop fussing and go to sleep. I guess someday is today. :)
