Example of the developmental problem: the child is about 2 years and 4 months old and has not spoken one word, he just usually yells or grunts or makes other noises to show is happiness or sadness but he does not speak. He wont always respond when you say his name and he does not even know how to say his own name. I have known this child since birth and have never heard him say a single word. Is that typical? or is something to be concerned about?
SO what's the best way to bring this up and mention something?
