Please help this family

My brother, a hardworking man, the sole provider for his family, was in an accident yesterday. Doing, of all things, hanging Christmas lights. He fell from his roof, fracturing his skull, breaking both wrists and breaking his right femur. He is currently in surgery having one of his wrists and his femur repaired. His wife is a stay at home mother, and they have 3 boys and are also raising our little sister. With him being the sole provider for their family he will be out of work for some time as healing from his injuries can take possibly up to a year if not longer. My concern is giving them some financial help with him being out of work, as they do have a mortgage, utility bills, a car payment, children to feed, as well as Christmas coming up. If you could find it in your heart to help my brother and sister in law in this time I would greatly appreciate it.
