trigger Autism Spectrum Disorders (ASD) symptoms? I have noticed minor things from difficult child for a couple years now but things seem to have become so much worse since he hit puberty. easy child/difficult child has only really been displaying behaviors since he hit puberty. Just wondering if anyone else has had this happen with any of their difficult child's and their diagnosis's. easy child/difficult child is becoming more Autism Spectrum Disorders (ASD)-like by the day. I'm afraid to admit it but it might be time for me to admit I have 2 difficult child's. UGH.
