She may have sensory issues. She sounds a lot like my older daughter at that age. Things with her did not really peak until about age 7 when I realized she was starting to get worse, not better, for her age. The raspy voice makes me think of something else that we have going on as well, which is strep problems. A lot of the parents at the support board I frequent say that their children have constant raspy voices.
A lot of times children with chronic strep issues do not present with typical fever and sore throat like you usually think. They will instead present with a variety/range of other issues like sensory issues, fatigue, random aches and pains, day or bed wetting, allergies, dark circles under eyes/glazed look in eyes/wide pupils, fixation or ocd type behaviors, liking to lift heavy objects and lug them around, having to have/do things "just so", panic or rage for no logical reason, random fevers or other weird symptoms that are not linked to anything that you can figure out, strange rashes or skin problems that come and go, sleep issues, being "precocious" with language or motor issues (on the flip of that some are delayed as well), tics or repetitive behaviors (sniffing, throat clearing, nose picking, skin picking, lip biting, eye blinking, etc are some milder ones)
PANDAS is the acronym that is used to name the condition for strep issues that affect the brain in small children. What happens is the body does not react in a typical way to fight a strep infection and instead attacks itself (particularly the basal ganglia) and you see a whole variety of symptoms, depending on the severity and depending on the child.
