Someone needs to research hallucinations as that is the cause of all mind disorders in children. I have done research on it and mind development and both are about images; shock and distorted images. Looking at their symptoms like spinning even suggest it. Different in Girls and boys is because of innate different likes and hormones/different response level. Spectra is obvious due to differences in hallucinations, intensities etc. It is time to find out what is causing hallucination in infants, and young children; and you will not see them. That a fallacy about hallucinations as all you see is their reaction; and in young children, that is the illness. we need to look for the cause and or causes as there may be many and or just one main one.
