Welcome to HCM
We understand your concerns
I went through your problem descriptions. I suggest, why, in the first you suspect that your child has Semantic pragmatic disorder? The Semantic pragmatic disorder is related to autism
, Asperger syndrome
Let us wait for the diagnosis. Before concluding, please check with two or more psychiatrists / physicians. Your son is just 2 and half and still he can cope up with the help and nurturing you provide. He need love and affection and not diagnosis and medicines.
Hope you understand. Available for further clarifications.
