My Sister s son, he is now 3 1/2 yrs. When he is around 10 months, he used to interact quickly. He will grasp things quickly and react properly. We were very happy about that. After that my sister gone to abroad and she came 2 months before. We noticed that he is not having eye contact with others. Not sitting in one place for more than 2 minutes. He is enjoying himself. He is playing and living in his own world. Not responding and not replying. But good thing is he hears wahtever we say, sometimes he looks at. He observes everything and when he is alone he is repeating whatever happened before or whoever he saw before. Not he is not talking, sometimes he talks something very slowly. Doctors please advice what we can do. Please let us know how to cure this.

DearWelcome to ChatDoctorWe understand your concerns went through your details. I don't think there is anything to worry in the children behavior. He is living in his own world, playing and creating a situation where he can play with himself. I strongly feel there were no playmates for him to play with. In such cases, the child Chat Doctor.  This too is part of development and is healthy. You mentioned, he is not sitting in one place for more than 2 minutes, and he is avoiding eye contact. You have observed these two closely. Fidgeting child without eye contact in every aspect, irrespective of any given occasion, could spell trouble. In that case you should consult a child psychologist. Nothing to worry though, can be corrected with therapy. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
