My son was diagnosed at 3 yr, 5 months...he is now 15 yrs old. DS was very sharp...I can remember taking him to a doctor appt at approx 15 months and the doctor remarking on how precocious he was...and it wasn't echolalia. Charles hit all his milestones early, particularly the social ones...then at around 18 months he stopped talking one day. We still had occasional good days, and he'd been far ahead so even though he wasn't progressing he was still at the right spot at his 2 yr check-up. I sensed something was wrong, and the summer he was 3 I took him in...DH is AF and we were being transferred to Iceland...the doctors said DS was fine, not to worry. Five months later we had a diagnostic team from England check DS out, got two diagnoses that day...PDD-NOS and ASD...same thing, different terms from different professionals. The AF sent us back to California, I became involved w/ a strong parent's group and Charles had an ABA program w/ oversight from the Lovaas team within 6 months of diagnoses. After a short time the regional center began paying for the program, and our school district has always paid for whatever I asked for. Right now we're doing biomed stuff...out of pocket...this seems to give the best results ever. Yesterday's Thanksgiving was the best he has had since he was three yrs old...he always sat at the table, had beautiful manners...but yesterday he was into it !!! Had nothing but 2 yogurts for breakfast, than didn't eat till dinner at 4:30...happy and waiting in the living room when our guests arrived...willing to try new foods. Then this morning he wanted to listen to Christmas carols in the family room...the season has kicked in.
