I finally have a photo of Sophia saying “BIIIIIIIIG” and making the matching exaggerated action of showing something big with her face and body all tensed up almost as if she’s convulsing. Its really cute to watch. We always wondered who taught her that. She just did that on her own accord one day when she saw a very normal sized cat near our apartment and my personal suspecion was its a reference to the leopards and jaguars that we saw earlier that day at the zoo. But nobody can be sure. Its just her thing.
