We have told our son that he has FAS because his birth mother drank alcohol during her pregnancy. We have not told him that he has a low IQ which may or may not be associated with FAS. Each child with FAS has some different characteristics due to genetics, how much alcohol was drunk at what exact stage of development. Our son is very impulsive and has very little understanding of numbers. He has also been diagnosed with Reactive Attachment Disorder and Post Traumatic Stress Disorder. He was neglected, physically and sexually abused which complicates things. He will definately need us to be guardians since kids with FAS often have little concept of money. I’m not sure what you mean when you say your daughter lives in a fantasy world.
