Top 10 First Birthday Party Themes for 2026

Still the most popular first birthday theme in Chicago, and for good reason. "Wild One" is a play on words that works perfectly for a first birthday. It's versatile - you can go full safari, boho jungle, or somewhere in between.

How to pull it off:

• Decorations: Green balloon garlands with gold accents, tropical leaves, animal figurines. A balloon artist can create an incredible safari arch.
• Cake: Safari animal cake or a simple one-tier with "Wild One" topper and greenery. Gold and green color palette.
• Outfit: Animal print romper, khaki outfit with a safari hat, or a custom "Wild One" onesie.
• Activities: A traveling petting zoo takes this theme to the next level. Several Chicago vendors bring goats, bunnies, and chicks right to your party.
• Best for: Backyard parties, park pavilions, venues with outdoor space.

The groovy, retro smiley face theme has exploded in popularity. It's gender-neutral, cheerful, and incredibly photogenic. Think 70s vibes with a modern twist.

How to pull it off:

• Colors: Mustard yellow, muted orange, sage green, warm brown, cream.
• Decorations: Smiley face balloons, daisy garlands, checkered tablecloths, retro "One Happy Dude" banner. Chicago decorators love this theme because of the bold color palette.

Another perfect first birthday pun. "Donut Grow Up" gives you a fun food theme that's easy to decorate and even easier to cater. Plus, every guest gets donuts.

How to pull it off:

Bonus: No Theme Required

Not every first birthday needs a theme. A beautiful color palette (think: dusty rose and gold, sage and white, or classic blue and white) with a gorgeous cake and good company is all you really need. Some of the most stunning first birthdays we've seen in Chicago are simple, elegant, and focused on family rather than Pinterest boards.

The best theme is the one that feels like your family.
