Non-profit organizations such as Make-A-Wish specialize in giving once-in-a-lifetime experiences to children with deadly illnesses. Though vacations and expensive items are the most common wishes, a lot of children wish to meet celebrities. This can result in one-on-one meetings or even the celebrity taking them to visit the set of whatever they're working on.
However, the Make-A-Wish Contribution takes this even further. Sometimes, a child's wish request will result in them causing something in the work to exist. This can be a cameo, a background detail inspired by them, or suggesting an idea that ends up in the work.
Sometimes is a case of Throw It In! or a Promoted Fanboy. This can be an Actor-Inspired Element if the person is acting in the work, or a Memorial Character if the child passes away. A sub-trope of Reality Subtext. Compare Contest Winner Cameo and Official Fan-Submitted Content.
Note that this is exclusively an American trope, as the Make-A-Wish Foundation only operates in the U.S., through there's similar organizations in other countries.
