Lives with order - father does not accept ASD diagnosis

My best friend (F37)is having a rough time with the support worker assigned to facilitate the court order and produce the lives with plan. 

The support worker has confirmed the father (M40) does not accept his son (M6) has ASD (because he was not pre warned about the diagnosis referral). He has stated his son does not show any traits his cousin (also diagnosed has). 

The social worker has stated they cannot make him support ASD needs and is happy about the care being provided.

My best friend has been told she is not to take her son to the Dr's and imply any outburst, episodes or anxiety related symptoms are related to the lives with order. She has been told that her completing a child safeguarding course is hindering things as she is reading too much into the traits and symptoms her son shows after contact. I.e. lashing out, excessively scratching his arm until it bleeds, nightmares etc. 

Can anyone provide any advice for this?

She has tried to set up a calming routing for when he comes back from his father's, it works for a little bit but then the smallest thing can undo the calming routing and it is back to square one. She has bruises and cuts from where he lashes out the days he comes home.

  • Go back to her solicitor and get more information? It's difficult when there's a court order in place. It sounds as though the parents have split up, is it the split and its surrounding hostility thats causing the child to act out? If he's itching enough to scratch himself so badly he bleeds, then could it be an allergy to something like milk, soaps, laundry products etc
