How do you respond when your child says something like this? LO is 2.5 and says these things often (usually when she's tired). She does at least say them politely ("Leave me alone please" or "please don't talk to me!"). I'm hesitant to react negatively because I want her to be able to express herself, so I usually say something like "Ok I understand just let me know when you're ready to talk." But I have no idea if that's the right thing to do. How do you react?
