I don't have a child in speech therapy but I do have an ASD child and can tell you that conflicting specialists are a problem. My son has global delay disorder which deals with fine and gross motor skills. We had 2 different therapists working with him, each of them had their own goals, etc. I was very confusing to my son. It is my opinion that working with one therapist at a time is the way to go. If the therapy at the school is working then I would just continue that.
