My son is almost 9, smart, does well in school, has ADHD, and is an overall "good" kid. He is very sensitive in the fact that he cries easily. If someone in power (teacher, parent, grandparent) speaks to him in a loud voice or critizes him, then he will cry. While doing homework, if he gets a question wrong or has to redo a part, he will cry. I was a sensitive child too and still as an adult. I am a single parent. When he cries, I comfort him and try to figure out why he is crying. Most of the time the response is "I don't know." Is this normal behavior? Could there be more to this than just a sensitive child or is it just in his genes?
