Surgery for newborn with TGA

This is my nephew Brian Cha, born on 7/31/2019. He was born with a heart defect known as transposition of the great arteries with ventricular septal defect, This basically means the positioning of his main arteries are in the wrong order and his body is not getting oxygen-rich blood.

The surgery is being done at Children's Hospital in Seattle and I believe they have some sort of grant to help parents offset the cost of huge operations but the expected cost is somewhere in the hundreds of thousands of dollars. 

I am submitting this gofundme on my brother's behalf and am asking for any help anyone can give because they have 5 other children and could use any help they can get. Any amount will be appreciated.
