(Your older sister, Kate, is 16, and you are 14, but she has bio-infantilism, so she is baby-sized, wears diapers, has not started teething, can talk like teenager, and does other baby stuff, and she sleeps in a large tent. She also hates wearing anything over her diaper, but puts up a fuss if you change her diaper, wanting to only wear it, but can be soothed at any time by coddling her) Kate is crying one morning in her tent
