My brother has just turned eleven and licks the tips of his fingers. He doesn't necessarily seem aware that he is doing this, although, when told to stop he does. At first, it was questioned whether it was an aspect of anxiety but he does it all the time. He can casually just watching the television and he will lick his fingers.
It doesn't sound like he has aspergers, my daughter is 7 and has aspergers syndrome...she doesn't like to look people in the eyes it took her until she was 4 to talk she wasn't potty trained until 5 and has been in special needs classroom since pre-k. I don't know why he is doing it but can guarantee that he doesn't have A.S. please don't try to put him in the autism category and have him misdiagnosed. Unless he has more symptoms kind of like my daughter then you should consider A.S.
