I am not quite sure what you mean by help her develop normally? What exactly are your expectations? How severe is her ASD? The child is going to have a different developmental path than their peers. ASD is not a curable condition. It is just treatable depending on what sort of symptoms come up and what she needs individual help with like sensory processing issues.

Right now the only thing I can think that would be beneficial is probably what you are already doing. Child psychologist and a occupational therapist. And a lot of understanding!
