Your baby won’t remember their first birthday. You will, and so will the grandparents, which is why first birthdays are often the most carefully planned party a child will ever have. Here are the themes we see families fall in love with.
Wordplay themes
Party sites like The Bash list playful “one” themes among 2026’s favourites. Our most-loved versions:
- Wild One: jungle and safari, perfect for active little explorers
- Little Star / Twinkle Twinkle: dreamy, soft and timeless
- One Happy Camper: tents, pine trees and woodland friends
- Berry First: strawberries in soft pinks and reds
- One-derland: an Alice in Wonderland tea party
Storybook themes
Peter Rabbit, Winnie the Pooh, Bambi and Little Prince feel gentle and classic. They photograph beautifully and won’t date.
Animal themes
Woodland animals, farm, teddy bears and safari all suit babies who are starting to point at animals and make the sounds.
Adventure themes
Hot air balloons (“Oh, the places you’ll go”), little aeroplanes and travel themes suit parents who love a story about the year ahead.
Styling tips for first birthdays
- Soft, calm palettes so the baby isn’t overwhelmed
- A photo corner for family portraits
- A cake-smash setting if you want those photos
- Comfortable seating for grandparents
- A quiet room for naps and feeds
