Goodmorning, I know this is years later to your original post but I have to tell you, YES the ADOS can be wrong! A mother knows her child the best so follow your instinct. Please also remember that every child is very different, and no child with autism will present the same way. DO NOT let professionals tell you otherwise. Diagnoses shouldn't matter but as I'm sure you've found out insurance companies think they do. Services that your child needs are directly related to on paper diagnosis. I hope by now you've got a more clear picture for your child. Good luck and God bless. AspieMom
