Yes- I am positive it was Livie spitting on the couch. The wall. The floor. The TV. Yesterday she spit it Isabel's hair. Eew. And she just now chased Taj spitting at him. I don't know what to do with her. Duct tape, perhaps??
Oh, and no, I can't prove the boogers were her's. Maybe they were Sei's- except he wasn't home...
