DS is 11 and the things he loves are:
Anything with wheels: he has 3 bikes, 2 skateboards, a hoverboard and a scooter 🙈Accessories for these like ramps, kit for his main hobby which is BMXing.
His MacBook, AirPods, Beats headphones, IPhone, Apple Watch, anything Apple basically.
His football net, football accessories or kit, basketball net, hockey stick and baseball bat, ball and glove set.
His paddle board although that might not be the best Christmas present unless you happen to live in the Southern Hemisphere.
Art supplies, books, he’s only into Harry Potter lego now really but he also wants the Mario sets.
Surf/ skate/ bike brand tshirts, hoodies and trainers.
He really wants a Switch but getting hold of one is proving very difficult! He rarely plays on his PS4 though so I’m not sure a switch would be any different.
Some of these would work for girls too.
