No one child with ASD will have exactly the same symptoms as another child with ASD. Here are some signs of Autism: Limited or no eye contact, do not respond to pointing, do not respond to their name, flap hands, spin, rock, picky eaters, gags alot, constipation, language delay, repetitive words without understanding, regressed at about 15-24 months, destructive, sleeping problems etc. Visit your child's Pediatrician if you are concerned about your child's development. If you are uncomfortable with the doctor's advise then I advised you to seek a second or third opinion. Also pray fervently for your child, God does answer prayers.
