My eight year old son cannot speak or communicate at all, he has daily meltdowns, and cannot stand on his own. He is like a baby that never hit any milestones. He's never crawled or pulled to stand, and loud or sudden noises make him cry. He is missing a piece of DNA (chromosome 9q22.2) but we are unsure if it made him disabled. He has a diagnosis of partial agenesis of the corpus callosum, microcephaly, and infantile Autism.
