MY baby!!

We met up with a friend at the park today. We sat the babies up next to each other to get a picture, and suddenly Kate got... I don't know... jealous?? protective?? Whatever it was, she did NOT like that other baby getting too close to her sister and she felt the need to claim her turf. It was really funny; I've never seen Kate act that way towards Caroline. I just kept snapping, 'cause that's what I do...
