This week, 52 Lives is trying to help a 2 month old baby girl get to hospital safely.
We heard about this little girl from one of the medical professionals who is working with her.
When she was just a few weeks old, she was diagnosed with neuroblastomas on the brain - it is a type of cancer that affects young children.
She is undergoing chemotherapy at the moment, has a line going straight into her arteries for the treatment and has to be tube fed.
Her mum takes her to Great Ormond Street Hospital in London for regular treatment, a journey which cannot be made by public transport as she has a low white blood cell count which makes her susceptible to infection.
This is where all of you come in.
The baby's mum is an amazing woman - positive, caring and incredibly strong. But she has very, very little money. She is having to make the regular journey to the hospital by taxi - something she simply cannot afford to do. But, with her daughter's life at stake, she can't afford not to.
