Yikes! Poor couch! I would, for a period of time, only let her roam about when you are home to watch her, and say "No!" when she starts to attack the furniture! Is the living room right off the kitchen, or is there another room between with less tempting furniture? How old is she now? One month old seems to be awfully young, and it's possible she's teething, so make sure she has plenty of okay things to chew on, that are tastier than the couch!
