TJ has a bad habit of sometimes getting too close to people's faces.
With his blanket, which he flops all around, his hand, or sometimes his face. It is a phase, it will pass. Julia, however, doesn't know this.
He got too close to her face once too many times and CHOMP. She bit him right on the nose. He was crying and crying and she just walked away with her stumbling steps, got onto her red Mickey Mouse plane, with this very serious, "Yes, I am a badass baby, DO NOT mess with me" look and took a few steps backwards on it.
