Cousin bonding

My sister and her almost-2 year old son, and 4-and-a-half month old daughter are here visiting from San Francisco. We decided to have a sleepover at my mom and dad's house so the kids could spend some fun time together. We loved it! And everyone got to practice holding baby Makenna. (Most of the good pictures are on my sister's camera, but I thought I'd post the few I got.)
