Hi All! I've lurked here from time to time, just looking for answers and sometimes just to realize husband and I are not alone in raising DS. I have 2 kids, DS that is 4 y/o given Autism Spectrum Disorders (ASD) diagnoses at 2, but they are now saying they believe he maybe ADHD, Obsessive Compulsive Disorder (OCD), ODD, but won't diagnose so young. My other little one is 15 months, and shows none of the delays / social issues my older one showed. So it my older son in question here. He has had a compulsion to say the opposite of everything since language started during ST. At the time the therapist really blew off my concern for this odd habit, but now its grown into him being argumentative with everything. To the point that husband and I find ourselves avoiding interaction with him because its so exhausting and unpleasant. He denies reality. That's the best way I can describe it. Example: If we were in an aisle at the store, he might point at someone and say, "I don't see anyone there". At which point husband or I might say "yes there is a woman there." And he will say "No there's not." This would go on, so we don't even acknowledge these statements. When he was learning to talk with ST, if we said a word like "downtown" he'd get very angry and say "NO! UP town". If he saw a red light, he yell that the light was green. The therapists kept telling us that we should be amazed at his understanding of opposites, and to let it go, and it would stop. He used to argue with the TV and talking toys. We had a toy that said "Its learning time" and he'd yell "No it kearning time" Or "zearning time" or whatever rhymed, because if he couldn't think of the opposite, he made up a nonsence word. This behavior has decreased over the past year. Its like he is so driven to argue that it is his primary way to interact. The therapists and doctor don't really have any suggestions, and won't officially diagnose him this young, which I understand. I'm just wondering has anyone ever seen this before?
