Does your little one love farm animals? Try using a song they already know and love: Old MacDonald as a 3-year-old birthday party theme! Farm animal decor like hanging garlands and blow-up animals is super easy to find. You could even hire a petting zoo to come by for the kids to experience real animals, up close and personal!

2. Celebrate dinosaurs with a 3-rex birthday party

No one is too young (or too old) for a dinosaur birthday party! Since T-rex is factually the coolest dinosaur, dress your little one up and find some dinosaur decorations for a 3-Rex party. Be sure to include some themed party games like a dino egg and spoon race.

The only thing more important than the decorations is choosing the right venue for a 3-year-old’s birthday. Peerspace happens to have party venues for all ages and occasions. For example, your 3-Rex birthday party could be hosted at an outdoor backyard venue like this one in San Francisco, CA!

3. Throw a three-esta birthday party!

Celebrate age 3 with a three-esta party! You can include colorful paper picado banners and Mexican food. Have a custom pinata made with adorable broad hats and dancing music for guests. Don’t know where to begin? Check out Peerspace’s list of fiesta party ideas to get you started!

4. Get dressy with a threenage birthday

You still have a decade to go before you’re dealing with an actual teenager. But let’s pretend for a day with a threenage birthday theme. Dress up your 3-year-old like a little teen, put on popular pop songs, and include a little dancing!

5. Be cute little bees with a bee three party

A bee three birthday party is so much fun to plan! From honey-flavored desserts to bee costumes for the kids, you have a lot of creative potential with this 3-year-old birthday party theme. Make some balloon flowers using a yellow balloon surrounded by white ones and let the kids dance around them like little bees!

6. Swing from the threes with a monkey party

Is your little one an active scamp, swinging all over the place? Celebrate their inner monkey with a party to match! A swing from the threes birthday should have jungle decor with a few bananas placed here and there. With some cutout monkeys and a monkey suit for the birthday boy or girl, you’ve got an instant monkey party. Look for Curious George party invitations, decorations, and our Curious George party ideas to get you started.

7. Get medieval with a knights and princess party

Celebrate fairytales and chivalry with a knights and princess-themed 3-year-old’s birthday party! This is a fun theme for boys and girls alike since they can dress up as either. Include a few stories and fables featuring knights and princesses, medieval games, and a castle cake for added fun.

8. Be young, wild, and three for the day

A young, wild, and three party is one of the most fun 3-year-old birthday party themes because you can take it one of two ways! Some parents opt for a groovy party theme where it’s all about the freedom and style of the 70’s. Others opt for more of a wild animal take, with jungle or safari decorations, clothes, and food. Both are creative and fun approaches to any 3-year-old’s birthday!

Adjust our retro 70s party ideas and safari birthday party ideas to better suit the personality of your little wild thing for their party!

9. Ditch the wolf at a Three Little Pigs party

Storybooks offer a lot of potential for 3-year-old birthday party themes. One even has three in the name: “The Three Little Pigs!” Tell the Big Bad Wolf to stay home and bring this fun fairy tale to life with piglet decor, costumes, pink cupcakes, and games like pin the tail on the piggie.

10. Be three as a bird together

Fluffy yellow chicks, bright bluebirds, and clucking chickens are just a few of the feathered friends you can invite using this birthday party idea! Serve some marshmallow peeps as snacks or place them on top of the birthday cake. A few bird toys and egg shaped chocolates in a twig bowl makes for instant decorative bird nests that double as snacks for the kids.

11. Let her be Elsa with a Frozen party

Frozen is one of Disney’s most popular birthday party themes for young children. So how about letting the birthday girl be Elsa for the day, while you decorate a winter wonderland party venue for her? A few marshmallow, candy, and pretzel rod kits let party guests make snackale snowmen together. Don’t forget custom Frozen birthday invitations for the parents so everyone knows what the theme is going to be! 

12. Invite the neighborhood party animals over

What 3-year-old isn’t in love with bears, birds, snakes, and other critters? Invite the local party animals over for some fun with animal masks and balloons! This birthday party theme gets even better if you tell parents it’s going to be a dress up occasion. That way, they can dig out their favorite adorable animal costumes for the event and bring animal-themed gifts and snacks! 

13. Let them bloom with a born to be a wildflower theme

We all know the hit song so how about making it a little more adorable by tying flowers to the theme? Born to be a wildflower is a great girl’s party theme where you can include flower bouquets, floral hair ties, and flower-like party dresses! If there’s room for a crafts station you can even have the kids make flowers and flower-printed hats using construction paper!

14. Serve tea for three during a tea party

Tea parties get adorable quick when you dress up the little girls in party outfits and serve them tea alongside stuffed animals and dolls! Teach them how to pour sweet tea or juice without spilling anything and serve sandwiches cut into cute shapes and cookies. Be sure to use disposable cups and plates with floral print that won’t be so easy to break as actual tea cups.

15. Take them to Candyland

Kids dream of visiting Candyland one day, where the streets are made of chocolate bricks and the clouds made of fluffy cotton candy. So why not bring Candyland to life with this amazing theme? Pastel candy decorations are only the beginning, though. You’ll want a snack table to match, with lots of variety, like Twizzlers, chocolate eggs, and ice cream. And a Candyland birthday cake should be the grand finale!

16. Enjoy the show at a three-ring circus

Have you ever been to a circus-themed birthday party? This creative birthday theme includes animals for the kids that love critters. Yet it stands apart as a truly unique theme since you can include clowns, lion tamers, actors, magicians, and other ideas that wouldn’t fit in most of the other birthday ideas. 

17. Dive under the three together

A 3-year-old’s ocean birthday party could mean embracing “The Little Mermaid,” “Finding Nemo,” sharks, Spongebob, or something else entirely! Some of our favorite decorative snack ideas include sour green candy straws as seaweed, mermaid tail cupcakes, and sugar cookie seashells.

18. Blast off with a three-2-1-liftoff party

Space is always cool, no matter how old or young you are. Is your little astronaut ready to head to the moon, collect space rocks, and meet some aliens? Make the birthday event a three-2-1-liftoff party! You can include crafts like painting space rocks (lava rocks with colorful paint and glitter) as well as someone in an alien costume to get the kids screaming with delight.

19. Host an ice cream social birthday party

An ice cream party is the best theme for an outdoor summer birthday. The kids get to stay cool with a sweet treat. Plus you can make an activity out of serving them by building an ice cream station with colorful sprinkles, crumbled cookies, and other toppings. Once each kid has the ice cream sundae of their dreams, it’s time to dig in! 

20. Let them be dogs for a day with a puppy party

Dog-loving kids are going to adore this birthday party theme! Give out puppy ears and let the kids show up dressed as their favorite canine. You can serve birthday cake and snacks out of custom dog bowls with each kid’s name on them. The dog bowl dishes also double as party favors for the kids to take home after the end of the birthday.

21. Celebrate summer with a luau party

Do you want your 3-year-old’s birthday party to feel like a tropical vacation or beach party? Make it Hawaiian-themed using a few of our luau party ideas! Serve up some pineapple-flavored snacks and help them make flower leis and grass skirts to really get into the spirit. 

22. Pop everything with a pop-it party

We all know how much little kids love breaking things! So how about including all kinds of poppable items with a pop-it party? Bubble wrap, confetti-filled balloons, and bowls of confetti for tossing are just the beginning. You can include a bubble machine so they can chase bubbles around the yard and give out some pop-able toys as party favors at the end.

23. Sail the seven seas with a pirate’s life for three theme

Bring out their inner buccaneer with a pirate-themed birthday party. Besides pirate costumes, how about building a little ship for party games and parent photo ops? Pirate-themed games like a scavenger hunt are a lot of fun. A few chocolate gold coins scattered around the cake are sure to disappear by the end of the party!
