Does anyone have experience with genetic testing? It was suggested for our son but we said we would wait. Kind of thinking we don't need to know the cause of my son's issues. We are not looking to find why he is the way he is. But after reading about defferent topics (such Asperger's), it seems that genetic testing always come back as a clue to diagnosis. So now, I'm wondering if we should just go ahead with it. Our difficult child diagnosis is still quite uncertain, would genetic testing really help solve the puzzle?
