You seem to be reaching out for help. I don't know whether this will help or not, but: My son did not speak intelligently until he was 4 years old. I proved to be exceptionally intelligent and not on the spectrum at all. He, and every other kid I've come in contact with in 79 years of coming into contact with children, carried around a beloved object, to the exclusion of other objects, for several years while very young. I myself carried around a particular doll; and I'm not autistic. In general, if you are reaching out to help and if this is help: I would say take all this stuff from doctors with a grain of salt. Often, what they say is not based solely on their evaluations of the health of their patients but is instead based on evaluating the difficult they might get into if they do not recommend "further testing" or the equivalent.
