My son who is 6 yrs old and Rocks,he sits on the couch or in the car and rocks back and fourth,not all the time but when he is upset or tense,instead of hitting 99% of the time he finds some place to sit and rock and cry.He has done this since he could sit up,He also ask me the same things many times I answer him but he continues to ask.As a baby he would rather lay in his crib or his Johnny Jumper then be held .I once told people I was almost glad when he got sick then he was a little more cuddley.His cousin has Autism,what is weird is the almost had the same kind of birth -both c-sections,both of them had their heads turned in birth cannel,both me and my sister had infections and fevers after their birth.My son gets sooo obessed with certain things spider man,Mario-Lugivideo game it was all he could talk and pray at the dinner table about.Do you think he has slight Autism?
