Medical exp for severe car accident

My son Dakota Staples was in a very serious car accident on July 27th 2018 where he was the passenger. Doctors weren't sure if he was even going to make it. He was in ICU for 2 weeks with a bleed in the brain, swelling in the brain, contusions on the brain, protruding disks in the neck, ligament damage in the neck, a fractured lumbar, intestinal bleed of the duendum, fractured arm, fractured leg, and 6 cracked bones in the foot. He spent a week on a ventilator and in a medically induced coma. He has undergone several surgeries, so far one to repair the intestinal bleed, one to fix the fractured lumbar, one for the fractured leg, and one for the fractured arm. Dakota has had a feeding tube in from day one and a stomach drain. He is unable to eat or drink as of yet. Today he was moved to a Transitional Trauma Unit where he is in an observation room. He cannot walk yet. Once he is finally discharged from the hospital he will need to go into an inpatient rehab. His medical portion of the car insurance is close to being exhausted, he will have numerous medical expenses for months if not years. Any little bit will be greatly appreciated and a tremendous help.
