My 20 month old rarely responds to his name, is unable to follow simple directions and started showing signs of regression in communication. We are doing an allergy elimination diet as well as seeing a pediatrician that specializes in autism. Part of this may be selective listening, but watch carefully to see if he regresses at all in his speech. If he does, find a DAN doctor who is able to run allergy tests. You can find a list of DAN doctor's on the Dr. Sears website.
