No.

Pearl has learned the word "no." She first said it after she whacked me with a large lotion bottle in the nose and I said to her, "OW! NO!" She then said, "no, no, no, no." Now she loves to walk around the house chanting it every now and then. She has taken to saying it most often when she is in the bathroom and starts to walk behind to toilet to access the plunger and toilet cleaner. She says, "no, no, no" as she walks closer and closer (I have told her "no" for doing that a few times...).
