Eczema help

My daughters skin has looked like this for as long as I can remember. Her eczema seems to spreading rapidly and after numerous doctors visit I just get sent away with a new steroid cream or moisturiser. She is miserable. Any advice? I feel like the worst mum ever because I can’t help her. Also since pictures taken this morning she is now covered in head to toe including face and nappy area. We have seen a doctor today who just gave us new cream.
