Five Trendy Themes for Children's Birthday Parties 2023

When it comes to decision-making, there's one audience that knows exactly what they want for their birthday party: kids! It's always fun letting our party-planning imaginations run wild, and one of the key challenges is keeping up with their latest fascinations. In a blink of an eye trucks are out, dinosaurs are in, and all your plans for a digger-themed bash are up in the air. With their interests moving at speed, we share the top children's birthday party themes we expect to be big in 2023.

The Little Mermaid

Making its long-awaited summer splash, Disney's live-action version of The Little Mermaid enchants a whole new generation. Under-the-sea adventures are always great source for captivating party decor: think bubble balloons, treasure chests, pastel corals, and cute sea creatures cutouts to set the scene.

Little ones adore the film's cutest characters: we're picturing a Flounder-inspired craft zone where budding artists can create miniature sand masterpieces. Older children will be spellbound by an immersive cave of curiosities, filled with Ariel's treasures and interactive bubble show from the sea king. An iridescent landscape of jellyfish lanterns could illuminate the space and a storytelling sea witch might even be on hand to tell a tale or two.


Eighties computer game legends Mario and Luigi are also making a comeback to the big screen this year. When it comes to bold birthday party themes, it doesn't get much more colourful than this, with plenty of iconic characters to inspire decorations and entertainment programme.

A racetrack would be the perfect focal point and can be incorporated in so many different ways: from race course building and Scalextric track hire to retro racer ride-ons for little ones and the real go-karting for older children.

Of course, it wouldn't be a celebration without an appearance from the moustachioed plumbers themselves. For extra kudos, we can install a mini-arcade of retro video games to keep nostalgic parents happily occupied too.

Addams Family

For children that aren't all about glitter and bright tones, there's a more rebellious idol in town - Wednesday Addams. The hit Netflix show, partly directed by the gothic fantasy king Tim Burton, offers some pretty spooktacular party ideas.

Make a monochromatic statement with a cobweb balloon wall, fill the ceiling with a cauldron of bats, and use light projections and smoke machine to complete the Addams Family vibe.

As a homage to Wednesday's psychic powers, we can invite the guests fashion their own crystal ball while tucking into devilish snacks served by Cousin Itt. And don't forget about science show turned into a potion making workshop and a magic show for the thrill-seekers. For the grand finale, go with a stylish paper disco and a funky dance class to recreate the memorable Rave'N dance from the series.


We predict polka dots, black polka dots with a crimson to be exact. No, this isn't a mini-beasts theme (although that's another one we can get on board with) - it's modern-day superheroes - Miraculous Ladybug & Cat Noir.

These Parisian teenagers are inspiring a new generation with their magical tactics for fighting evil. Central to their powers are cosmic beings - Kwamis, the perfect colourful emblems for a creative face painter to mimic! We envision the dress up corner and green screen video making workshop also being a big hit for that party theme.

With two lead characters, this is the ideal chance for BFFs to buddy up for a double celebration. It's a great excuse for a super-sized two-tier birthday cake and personalised masks for their guests to take home.


From eighties cartoon to nineties live-action film - the Teenage Mutant Ninja Turtles have been reimagined several times over the years. The latest offering in the franchise sees a super-cool computer-animated version (Teenage Mutant Ninja Turtles: Mutant Mayhem), set to be one of the biggest film releases of the summer.

We can't wait to bring a slice of New York to proceedings with playful nods to their underground home. If ever there was a party that called for a slime alchemist, it's this one - and when it's time for a bite, authentic food vendors will be on hand to serve iconic NYC slices - Michelangelo's favourite snack.

Oh, and don't forget our digital graffiti wall and parkour workshop - for these who want to become a true kind of the streets of New York along with their favourite heroes!
