Mae Fox's parents have put together an appeal on Youtube to help them raise the £70,000 they need for an operation in America.
The four-year-old, from Doncaster, has been given the chance to have an operation in America - which will hopefully help her walk.
Mae Fox's mum, Amy Wildsmith, says it would give her daughter independence if she could walk.
The parents of a four-year-old girl from Doncaster face a race against time to raise tens of thousands of pounds for surgery which could change her life.
Mae Fox has cerebral palsy and needs a walking frame and wheelchair to get about, but now a hospital in America is offering treatment to help her walk - but it comes at a price - and with a deadline.
To get about she crawls, uses a wheelchair or a walking frame - or her new favourite toy - a bright pink car.
But now her parents have launched an appeal to raise £70,000 by Christmas for an operation next january in America. The dream is that the suregry would allow Mae to walk unaided.
