21 Creative 1st Birthday Party Themes 

Is your littlest member of the family about to celebrate their first birthday party ever? If so, congratulations! We know how excited you are to plan something spectacular for them. So how about a few creative 1st birthday party themes to get you started? Let Peerspace give you a hand with the party planning. After all, it’s what we do best!

1. Throw them a one-in-a-million party

Let everyone know how truly special your dear one is with a one-in-a-million 1st birthday party! Use personalized decor with your baby’s face; custom-made garlands, plates, bowls, and gift paper are the way to go here. Color choices are up to you but many parents opt for minimalistic shades to go with the simplicity of 1st birthday party themes like this.

2. Choose all the colors with a rainbow party

Children love colors and if they haven’t yet picked their favorite then include all of them with a rainbow party! Rainbows have symbolic meaning as well; they symbolize happiness, hope, good fortune, inspiration, and change. All things that we wish for a 1-year-old!

Rainbows as a 1st birthday party theme should be celebrated in a colorful venue. Did you know Peerspace has venues for color-themed birthday parties? For example, our vibrant rainbow room in Central Los Angeles, CA, has endless potential for rainbow parties and photoshoots!

3. Plan an adorable “bee-ing one” birthday

Let’s face it: bee outfits look adorable on one-year-olds! As a birthday party theme, “Bee-ing One” has a lot of possibilities. From bee-themed decor like flowers to yellow honey cakes and striped gift paper, you can throw a memorable 1st birthday party with ease using this idea! It’s also ideal for boys and girls alike. 

4. Relive your favorite fairy tales with a “one-ce upon a time” theme

Children of all ages love stories about fairies, elves, princesses, and knights. So how about recreating the world of fantasy with a “One-ce Upon a Time” theme? Your color choices are going to include a lot of pastel pinks, blues, greens, and other similar colors, with plenty of fairy dust in the form of glitter!

5. Throw a puppy party to make them even cuter 

Are dogs your birthday boy or girl’s favorite animals? Then put on some dog ears for them and make it a puppy party! You can have little stuffed dogs with party hats placed strategically around the venue. We’d also make some cookies shaped like dog biscuits for guests to enjoy!

Our unique dog birthday party themes let you celebrate your furriest family member in style. Check them out!

6. Visit Candyland with a “sweet one” birthday

The whimsical beauty of Candyland is one reason why 1st birthday party themes like this are perfect for youngsters. Imagine decorating the venue with giant pink frosted donut balloons, peppermint canes, and larger-than-life sprinkles. The cake should look outrageously colorful, with frosting touches that replicate ice cream scoops, foil-wrapped candy, and cookies, even!

7. It’s their berry first birthday party

Your little one is as sweet as strawberries so why not make fruit the theme with a berry first birthday party? If you decide to go with strawberries then you’ll want pink and red decorations, invitations, and a strawberry cake. The same goes for blueberries or other berry choices. Looking for tips on food options for color-themed parties? Check out our articles on red food ideas or blue food ideas to get you started!

8. Bring over all the animals for a farm party

Little pink pigs, adorable baby lambs, yellow chicks, and other farm animals are a wonderful theme to work with. After all, baby animals aren’t as cute as your little one but they sure come close! Your decor options are just as much fun, with bales of hay, tractors, cow-spotted table covers, and more to consider. 

9. Go down the rabbit hole for an “Alice in One-derland” birthday

Few stories are as charming and whimsical as Alice in Wonderland! If this is one of your favorite fairy tales then bring it to life with an Alice in One-derland Birthday party! We love how the above example brings the story to life, complete with an adorable Alice, fluffy rabbit, a mushroom, and tea party garden plants.

10. Bundle up and celebrate in a winter one-derland

The puns never cease when searching for creative 1st birthday party themes! Fans of Frozen should think about a winter one-derland birthday for their littlest member of the family. White and blue go very well together as party colors, for starters. The theme is all the better if the birthday party happens to be a winter date! 

11. Sweeten up the day with a “one in a melon” party

Pink and green go so well together, especially when used for a sweet “One in a Melon” birthday party! Watermelon is the theme of the day so try finding a cake frosted to look like one. This is a colorful party theme that’s one of the most unique on our list and ideal for an outdoor summer birthday party when you can serve cool watermelon slices! 

12. Head back to nature with a “wild one” birthday party

Is your one-year-old an active little scamp? Then a “Wild One” birthday party is just right for them! Dress them up as a little bear or tiger and decorate the venue with a jungle theme. Hang a monkey or two from the ceiling along with some animal-printed garlands. This 1st birthday party theme is more popular for boys but there are plenty of girls who qualify as “wild ones!”  

13. Visit the Hundred Acre Woods with a Winnie the Pooh party

Winnie the Pooh is another one of our favorite stories for children that make wonderful birthday party themes. Pooh Bear decorations like stuffed bears or even a cake that looks like him are easy to find. A little red t-shirt for the birthday girl or boy of honor is a must-have as well. And don’t forget a few of Christopher Robin’s favorite friends to tag along; Tigger; Rabbit, and Eeyore props should be included!  

14. Let them be loud with a lion party

We all know how much our little ones love to work out their lungs when they want something – and they want it now! These little lions deserve a 1st birthday party theme to match, don’t you think? A lion-themed birthday uses similar decorations from our “Wild Ones” idea; jungle or safari colors are best. But you’ll want to stick with lions for the animal decorations, cake, and any outfit you might dress them in.

15. Brighten their day with a color party

Red, blue, yellow, green, pink…What color do they like best? Color parties are fun for all ages, adults included! Dress them up in an outfit to match the occasion, along with colorful decor and some of Peerspace’s color party food ideas! If your kid doesn’t yet have a favorite color then go with traditional hues like blue for boys and pink for girls.

You’ll have an easy time making color the theme of a 1st birthday party if you choose a venue that’s designed for the idea. Peerspace has venues like our retro pink room in Los Angeles, CA, where you can instantly have a space for a rocking color party.

16. Celebrate her magic with a “she’s magic, that one” party

A new child coming into the world is truly a magical affair! Make the joy and wonder you feel at her presence the theme you choose with a “She’s Magic, that One” party. Best of all, magic is an idea that lets you use ideas from many of our other 1st birthday party themes, including princesses and fairy tales.

Love this idea? Then our adorable princess birthday party ideas are on hand to provide more inspiration!

17. Go fishing with an “o-fish-ally one” party

Nautical 1st birthday party themes are definitely a thing! If your little boy is shaping up to be a man of the seas then celebrate with an “O-Fish-Ally One” birthday party. Nets, fish, poles, and the sea are a few places to start. But check out the truly creative cake idea we have here, with wave-shaped frosting and fishing bobbers as decorations.

18. Make it a monster party for your little one

If you call them a little monster on occasion, celebrate their inner tyrant with a monster-themed birthday party! Decorative eyeballs, fuzzy monster cupcakes, and a birthday outfit for the boy or girl of honor are some ideas to use for this theme. Monster parties are especially colorful themes to work with as well if you’re looking for something bright and cheerful.

19. One-der woman is here to save the day

Unleash her inner potential with a superhero-themed birthday party! And what could be better than Wonder Woman? Or should we say “One-der Woman?” Blue, gold, and red are awesome colors to decorate with, especially when a cape and crown in these colors are part of the outfit the birthday girl will be wearing.

20. Blast off with an outer space party

Celebrate their first trip around the sun with an outer space party! Astronauts and aliens await your little adventurer if you choose this party theme. Moons, stars, and planets should be central to the decorative scheme. And how about a cake that looks like the Sun or an alien’s face? 

21. Throw a “mr. one-derful” party for a handsome little gentleman

Dress clothes can look absolutely adorable on a one-year-old! We love this party theme because it’s a delightful twist on a more sophisticated adult look. Gold, black, and white are colors we associate with a cocktail soiree or New Year’s Eve party, but they sure work well for a 1st birthday party like this one.
