My DD has selective mutism. She was diagnosed at 4. We realized there was something wrong (other than shyness) when she went to 3k (school and teachers she LOVED) and never was able to speak one word the entire year. She started therapy a month before 4K and is not progressing yet. She has not spoken at school. She also will not speak to grandparents, other kids, aunts, uncles, cousins etc. Only immediate family. She also has trouble with even making eye contact with others and will not speak with me when others are within earshot.
It's more than just clamming up in social situations, it's debilitating. She cannot ask to go to the bathroom at school, she is not able to say she is hungry, sick, thirsty etc... She will not use sign language, cue cards or make eye contact. Luckily she is only at school for two hours. I am petrified of what is going to happen next year (full days). She will prob. end up peeing herself before going to the bathroom and she will not eat due fear the lunch room. yikes!!
