All wheelchair-bound little Harrison Thompson wants to do is play with his older brother.
Three-year-old Harrison was diagnosed with type 1 spinal muscular atrophy aged just one, meaning he is unable to walk and is confined to a wheelchair.
But his family say the youngster constantly amazes them with his thirst for fun and adventure.
Now his uncle Ryan Struggles, from Church Gresley, is raising money to buy Harrison a specialist £25,000 wheelchair which will allow him to get around better so he can finally play with his brother, Lennon, aged four.
The hi-tech wheelchair is not available via the NHS and Harrison's family are determined to raise the money because it would make his life so much easier, they say.
They want to get a SnapDragon power-chair, which will also mean he can get outside to play too.
The wheelchair includes a lift which would also allow little Harrison to sit on the carpet at nursery with his friends and reach the desks when he starts at primary school.
His uncle, who lives in Reading Avenue, says the family are confident the chair will improve Harrison's quality of livings he can do things with his brother.
The family has staged fund-raising events during the past year and are looking to raise £500 through a donating page on the internet. And now Ryan, 36, will complete a sky dive to add £375 raised so far to the pot.
Ryan's sky dive challenge is being supported by the Turbo Trust, an organisation that helps disabled people gain mobility using power-chairs, and takes place on Sunday, May 27.
The 36-year-old says he is paying for the sky dive personally, with the money raised via sponsorship going to Harrison's fund. The youngster lives in Wainfleet, Lincolnshire, but most of the family are based in the Church Gresley area.
The family know they have a long way to go to reach their target, but they are determined to collect the money to help Harrison, said Ryan.
He said: "We have been fund-raising for a while to get him some equipment he needs, it's not all provided by the NHS.
"One of the things he can't do is interact with his brother Lennon very well. We are hoping the SnapDragon power-chair will help him run around with him."
Ryan and four friends will take to the skies at Langar Airfield, in Nottinghamshire.
Ryan, who is a mechanical engineer, said: "It would mean everything to my sister. She's fought so hard for him in pretty much everything that she has had to do.
"Harrison has got to the point in his life where it is fundamental he gains mobility to prevent learned helplessness from becoming a behavioural trait that is irreversible."
