My little boy has always been a bit different. Some of his tendencies may be an inherent part of his personality but others appear more symptomatic such as severe speech delay and no infant babbling, obsessions with household appliances such as the washing machine and preference for turning on and off taps and lights exhaustively. He has also been prone to making and repeatedly following circuits since he was a baby. He has episodes of facial passivity and can be inclined to disappear into his own little world. Apart from all this he is very affectionate and loving and does have episodes when he is more sociable. Hearing problems have now been ruled out. Has anyone experienced something similar and has it been diagnosed as autism or something else?
