Do you know about Selective Mutism? – 您知道什麽是選擇性失語症嗎?
Selective Mutism (SM) is an anxiety disorder in which a child who is talkative at home is unable to speak in other settings, such as school. Parents often notice signs of SM when a child is 3 or 4 years old, and may spend a whole year in preschool without saying a word.
