Just an update on my son. i have noticed some improvements over the summer.
He has more words now and makes more attempts to speak. If he is having trouble saying a word, or can't say it at all,he prompts me to say the word to him a couple of times by pointing to my mouth and watching the movements my mouth makes when I say them. He can follow most directions. He also recently started answering Yes or No questions sometimes.
This happened without having any formal speech therapy (no services in the summer ) so I an cautiously trying to gain some optimism. If he made those improvements without help then I am hoping getting it now will make a huge difference.
