Actually, you don't have to worry. My nephew can't talk until he is almost three years old. His family used to be worried to death, but now he can talk all day. As long as you go to the hospital for a comprehensive examination, it doesn't matter if there is no problem. I believe the baby doesn't want to talk now, but he doesn't want to talk. Really don't need treatment. Don't be fooled by some unscrupulous businessmen using your anxiety.
