One of my summer camp students (3 years old) is a chatterbox at home but has not said one word at school. He parallel plays with the other kids and has told his mom that he has fun at school. We sing some songs after snack time and he smiles but does not sing. Today, his mom told me she is planning on getting him evaluated if he does not start talking at school soon. She had told me it takes him some time to talk to new people, but this appears to be taking longer than usual. My research keeps leading me to Selective Mutism. Whether it is that or shyness, I have been careful not to put pressure on him. This has gradually led me to stop initiating conversations because I don't want him to feel anxious. He seems comfortable in the classroom; he does not cry when his mom drops him off in the morning, he is good at following directions and appears to be having fun. Since he is content, should I just let him be? Has anyone had experience working with a child like this?
