The family of a young girl from Leeds are trying to raise thousands of pounds so that she can continue vital treatment for a rare condition.
Zoe Lightfoot has Infantile Neuro Axonal dystrophy. It only affects one in a million children and reduces life expectancy to just five to 10 years old.
For the past year the four-year-old has been taking part in a drugs trial to try and slow down the progression of the disorder, which has had a big effect on her speech and ability to stand or crawl.
So far they have reached more than £26,000 out of their £40,000 target.
