Hi, it sounds like you are looking for PCIT (Parent Child Interaction Therapy). I only know this because I am currently trying to set up the same service for my family as recommended by my sister (she is a psychologist). A trained therapist comes in, observes interactions, makes recommendations, and provides strategies. This is not a cheap service by any means but in some rare cases, insurance may cover. I would contact your insurance company, pediatrician, psychologist, and/or school support team to see if they could recommend someone. I hope this information helps!
