My son is 6 years old. For as long as I can remember he always had a fear for the dark. I just blew it off as something he will outgrow but it seems to be getting worse. He scares very easily and when he gets scared he is truly frightened. He notices every little creak and every noise and he will look around and say 'what was that?" He will run and hide under something like a coffee table. When someone talks too loudly he gets scared, when his baby sister cries he hides, he sees or hears something on tv that sounds weird he hides. There has been times he is playing with friends and he hears something and he goes running. I am very careful what he watches on tv because he seems sensitive to certain things and noises. Is this a hypersensitive child or is this something he will outgrow? Is this normal behavior for a 6 year old?
