My two year old is extremely stubborn. She knows how to talk just refuses to do it unless she has an audience. Her doc is having her evaluated because she never said a word at her appointment yesterday just made noises and baby talk. How do I get the extremely stubborn two year old to start talking big people talk more and baby talk less? I spend hours trying to teach her new words she just looks at me and screams stop. She doesn't want to learn unless it's something she decides on like opening doors and unlocking doors and unhooking car seats etc. and it's frustrating.
