My son is 14 months old, and from birth he refused to be held. We would have to put him in his bouncy chair or swing in order to get him to calm down. My mother in law could not understand this and whenever we visited she would try to force my son to be held, and he would cry and cry until she finally gave up and put him down. Eventually (months later) she came to terms with it and agreed that he's simply not like the other babies that she's been around and put him in his chair where he obviously felt more comfortable. Now that he's older and walking on his own, he will come over and give us hugs, but only on his terms. If we try to hug him longer than he's willing, he'll throw a fit and wiggle out of our arms.
He is showing other early signs of autism such as hand/arm flapping, spinning, lack of separation/stranger anxiety, obsession with parts of objects, repetitive behaviors and vocalizations, speech delay and soothing with objects. Considering that both my husband and I have AS (in the process of being diagnosed, but professionals seem to be in agreement so far), I would be surprised to find out that he's not on the spectrum at this point. He's starting the assessment process tomorrow morning.
