Harry gave Oliver's house a backyard makeover with Helping Hands, which is supported by the royal's charity, WellChild, which aids families and caretakers of seriously ill kids. The redhead spent time with Oliver and his brothers as he worked with volunteers to transform his garden into an outdoor space he and his family can safely use and enjoy.

Oliver has Wolf-Hirschhorn syndrome, a rare chromosome disorder that causes him to have profound and complex needs. His new backyard, the charity's 300th project, will help him develop physical skills and encourage independence. Oliver's mom, Elizabeth McOmish-Rooney, explained to Harry that Oliver wasn't previously allowed to play in the backyard with his brothers, Samuel, 9, Joseph, 8, Thomas, 6, and his twin, Jak.

Harry, who has been working with WellChild since 2007, later traveled to Leed's Children Hospital to learn more about children with tracheostomies.
