HELP 1 year old baby for Skin Grafting Surgery

Makoto, my 1 year old baby, was born with severe internal bleeding on his tiny right hand. Because of this he has to receive skin grafting surgery under general anesthesia at the University Hospital in Hirosaki, which is 4 hours away from his home. Doctors couldn't find the cause for the bleeding. Seeing the wound broke my heart. It healed, but now he has wound contracture which makes it difficult for him to move his thumb and index finder. The bone hasn't been growing well either. The Plastic surgeon mentioned that he needs the skin grafting to achieve better movement. He will have to stay at the university hospital for at least one month. We won't be able to get paid from my work because I’m staying with my son. This directly affects our financial situation. I'd like to raise enough money to stay with Makoto and support him as he needs without concern for money. Please help our family. We are grateful for any donation received.
