Big sister, little sister

We think Sofia is starting to get used to having Olivia around because she likes to check in on her every once in awhile. Sometimes in the morning while Sofia and I are eating breakfast she will ask "Where Olivia?" And when Olivia is crying she always states "Olivia crying now." My favorite is when we hear Olivia pass some gas and Sofia will jump and tell me "Change Olivia diaper." It's nice to see her so concerned with the little one!
