Thanks for replying. She has about 30 words she uses to label and request essentially. She does not combine words and babble a lot. She does understand speech but, her receptive language seems limited. She has a short attention span. So, it is difficult to teach her new things. I keep reading to her and teaching her body parts. She does not repeat words when I encourage her to. Then one day, she will use one word in context and I realize she was listening. I am really freaking out now because someone suggested Rett syndrome. Could that be it?
