1. Wild One

Celebrate your wild little one with a jungle theme called “Wild One!” Decorate with balloons or cardboard cutouts in the shape of jungle animals like lions, zebras, monkeys, snakes, and tigers. Use colorful hues of green, gold, and brown. You can buy faux leaves or trees to create an epic jungle environment! This is a popular theme, so many party kits are available for purchase online, making it even easier to create an exciting party for your guests. 

2. Mr. One-derful 

Is your handsome little man turning one? Consider throwing a “Mr. One-derful (Mr. Wonderful)” party to celebrate your sophisticated little guy! Create a fancy party environment by decorating with gold, silver, black, and metallic balloons. Dress your little man in a white button up shirt and a black bowtie, and you can even add some suspenders to make his outfit extra special. Mustache party decorations also work well with this birthday theme. 

3. Baby’s First Down/First Year Down

Got a football lover in the family? Why not commemorate your baby’s first birthday with a fantastic football theme? Decorate with balloons and streamers in shades of green, brown, and white, and decorate with toy (or real!) footballs and sports gear. Your baby’s smash cake could even be in the shape of a football. You can create a “scoreboard” chalkboard sign to write your baby’s stats (height, weight, number of teeth, favorite foods, etc). You can print some photos of your baby, and arrange them in the shape of a goalpost. You can also buy a green metallic streamer curtain to use as a background, and add a big “1” balloon in front to use as a prop for a great photo area! 

4. Baby Shark 

Baby Shark is still all the rage with babies and toddlers alike, and would make a great first birthday theme. In addition to the many party kits available online, you can come up with some creative “under the sea” games and treats for your guests. Add a bubble machine, a ball pit, or a small baby pool filled with toy sharks to please young party guests. Serve ocean-themed snacks like Goldfish, Swedish Fish, blue Jello, shark gummies, or pretzels dipped in blue frosting! 

5. “Donut” (Do Not) Grow Up

Donuts are a sweet treat that make an adorable party theme! As parents, we all want our little ones to stay small forever, so a “Donut Grow Up” theme works perfectly for the occasion! Create a cute backdrop by hanging some streamer curtains or string lights, and placing a giant donut balloon in front. Decorate with balloons and streamers in pastel shades of pink, purple, blue, green, and yellow. You can even create a “one” display by using a donut balloon for the “O” and adding balloon letters for “N” and “E.” Find confetti that looks like sprinkles. And of course, serve everyone’s favorite sweet treat, donuts! Ask around for local bakeries that can cater for your party. 

6. “One In A Melon” (One In A Million)

This cute theme is all about watermelons! Decorate with shades of pink, green, and black, and have plenty of watermelon-themed decorations! You can buy watermelon party kits online for simplicity, and add extra balloons if you want! Use red checkered picnic blankets as decorations or tablecloths, and add a few picnic baskets and flowers around the rooms. Your little one’s cake can even be decorated to look like a watermelon (or, if you’re trying to skip the sugary treats, just serve your baby watermelon instead of cake!). 

7. Twinkle Twinkle Little Star

Celebrate your shining star’s first year of life with this simple party theme! Decorate in shades of white, blue, silver, and gold, and create an environment that looks like a captivating night sky! You can create oversized clouds using white balloons or cloth, and you can hang large star and moon balloons all around the room. You can buy twinkling lights or a light curtain to add to the shining effect! Make a banner that reads: “Twinkle twinkle little star, ‘onederful’ is what you are.” Your baby’s smash cake can be white with a large gold star on top! 

8. My Rookie Year

If your family loves baseball, this is the perfect party theme for you! Celebrate your baby’s “rookie year” with a baseball themed birthday bash! Decorate with red, white, blue, and black streamers and balloons, and find some cute banners to display pictures of your little one. Your baby’s cake can be designed to look like a baseball. You can also get a chalkboard and write your baby’s first-year stats like weight, favorite foods, special skills, first words, and more!

9. The Big One/O-fish-ally One 

There’s not much cuter than a fishing-themed first birthday party - and it’s easy to find decorations and props to fit this theme! Celebrate your little one “o-fish-ally” turning one by creating an adorable party scene filled with fishing poles, toy fish, balloons, streamers, banners, and bubbles! Colors such as blue, red, orange, black, and yellow work well with this theme. Snacks can include fish-themed treats like fish crackers or gummy fish. You can also make blue jello or pudding. Decorate a birthday cake to look like rippling water, and add gummy fish to add to the look. Dress your baby in a tiny bucket hat and vest, and he’ll be ready to steal the show!

10. Sweet One 

If your little one is as sweet as can be, consider going with this candy-themed party idea! When purchasing decorations, think about everything sweet: ice cream, donuts, lollipops, cupcakes, and more! You can find balloons in the shapes of many sweet treats. Bright, vibrant colors really work well with this party theme. For party favors, you can make your guests little bags of assorted candies! Don’t forget that fruit also counts as a sweet treat, so you can also do this party theme around fruit instead of candy and desserts.

 11. One-derland 

One-derland theme

Create an adorable party based on “Alice In Wonderland!” The invitations and party banners can say “(Your baby’s name) In Onederland,” and you can decorate with brightly colored balloons and streamers, a deck of cards, teapots and teacups, feathers, rabbits, clocks, and more! If you have a baby girl, find a party dress to look like Alice’s dress - a white and blue gown. This theme is the perfect opportunity to throw a cute tea party for your little one and her friends! 

12. Baby’s First Fiesta

This theme is so much fun for babies and party guests alike! The “first fiesta” theme makes it simple to pick out party food: a taco bar, nacho bar, tamales, enchiladas, or rice and beans work well for this theme. Decorate with balloons and banners in bright colors like magenta, teal, neon green, and yellow, and think about elements that might suit this theme like an inflatable cactus, a sombrero, or maracas! Use mini piñatas as a great photo prop!

13. My First Rodeo

Break out the cowboy gear and get ready to celebrate your baby’s first rodeo! Colors like red, black, beige, and blue work great with this theme. Decorate with cowboy hats, boots, cactus, bandanas, and other wild west items to create a cute look for your baby’s birthday party. You can even use letter balloons to spell out “My First Rodeo” to create some great photo opportunities! 

14. Hole in One 

Do you have a tiny golf pro at home? This first birthday theme will suit him (or her) well! Decorate with shades of green, white, and blue, and add golf elements throughout the party scene to set the stage for your little pro in the making. Adding fake grass to look like a putting green, and get cookies or cake decorated to look like golf balls. This theme is simple, and yet unique! 

15. Look Whoo’s One 

“Whoo” is one? Your little baby! Try this adorable owl theme for your child’s first birthday, and your guests will be impressed. Decorate with trees, flowers, and owl cutouts, and shades of pink, brown, and teal, for a sweet party environment that is sure to please.
