A 2 years and 6 months old boy, it's my friend's son, doesn't know any words, not even mama or daddy. When he was over 1 year old his white blood cell count was high, from 23,000, 17,000 and now 12/11,000 count. Which we don't know if it is really significant to his case. Hearing was tested and it's normal. The child was playing alone but when he hears the sounds of the TV shows he likes,he stop playing and watched. The child is picky on the foods he eat.
