Baby Rare Aggressive Leukemia

My two and half months old baby girl has been in ICU for 4 days now.
We sent her to Emergency Room at 3am on 3/24/18 due to weakness of breathing and huge stomach. ER doctor found out she has an enlarged liver and transferred her to Lucile Packard Children’s Hospital.
Oncologist said she has a very rare type of cancer called neuroblastoma, only about 200 case per year in the United States.  
Her liver is larger than adult’s. The liver tumor is bigger than adult’s hand.
Cancer cell has been found in her bone marrow after the bone marrow testing, indicates she is in the highest cancer stage.
She had her first chemotherapy on 3/26/18. As of 3/28/18, her tumor has not shrunk yet. Radiotherapy might be needed later on this week.
One of the cancer genetic test results will take up to two weeks in order to determine if my baby girl is in the intermediate risk or high risk classification.
Please save my little baby girl. My husband and I and my first daughter want to bring my little baby girl home!
