You've given Tuesday's blog of the day the title 'My ASD child is not a genius but he is amazing'. ASD isn't an adjective and shouldn't be used like this - it's like saying Down Syndrome child or Special Needs child, which I'm assuming (hoping) you wouldn't do.
You could use either 'autistic child' (which is how the blogger refers to her son in the post) or 'child with ASD'.
