so my ds was diagnosed with pddnos last year. at this point i will state that i am not his biological mother, so to make a long story short: he was a neighbours child who was put into care and then she suggested we take him in and at that point i found out that she and my bf had a 'thing' right before i met him and may be the father...... anyways, today he had an appointment at a genetics clinic to get looked at and tested for fetal alcohol and drug syndrome based on a referal from his psychiatrist. they did alot of measurements on him and then graphed their findings and came up with the possibility of fragile x syndrome. after some reading up i find that a lot of fragile x kids are on the spectrum as well. he is going in next week to get the dna work started. i guess i don't really have any specific questions. i am looking for someone who may have experience with this or be in the same boat. i am of course hoping this comes back negative but would not be surprised because of his overly aggressive behaviour.
