Planning a milestone birthday party for your soon-to-be one or two year old? Since those first few years always fly by, it’s important to celebrate your baby’s big day in the most memorable way. So, we’ve rounded up the most popular 1st and 2nd birthday party themes to celebrate your not-so-little-anymore *tears* birthday girl or boy!

1) Magical One Rainbow Party 

Rainbows and one year olds go together like birthday cake and frosting, so this stress-free party theme is a guaranteed hit. Simply decorate with balloons and party fans in a rainbow color scheme, and layer some classic Happy Birthday banners on your baby boy or girl’s high chair.

For tableware, it’s all about these rainbow plates and matching runner. We also recommend these darling mini party hats, a must-have for every kids party!

The best part about this first birthday party idea is that you can mix and match any way you’d like to make it special for your little one. So, you can keep things simple and use classic birthday accents (like this multi color cake topper), or you can add decor inspired by whatever character or show your kiddo is currently loving. Trust us, this birthday theme compliments everything from Winnie the Pooh to Sesame Street!

2) Station No. 1 Fire Truck Party

If your birthday boy loves fire trucks, then this first fête idea is perfect! We recommend using lots of red and blue decorations and fire truck balloons.

We love these bright red fire truck plates and matching napkins. They feature an adorable “Engine No. 1” embellishment, making them ideal for first birthdays. To complete this party set-up, we suggest including some colorful table accents and a sprinkle covered cake. 

There you have it: the perfect fire truck-themed birthday party to celebrate the big 01! But if your kiddo prefers a different set of wheels, we have a truckload of other vehicle party supplies you can shop here

3) Once Upon A Time Princess Party   

If you want to bring a little more magic to your baby’s big day, consider throwing a fairytale princess-themed party! This Once Upon a Time banner and cake topper make for a perfect first-birthday party touch. As for other decor, think pretty pink tableware, sparkly banners, and crown and castle balloons–and don’t forget the tiaras!

No fairytale fête is complete without a glittery crown, and this multi-color pack is essential for transforming into a pretty princess. But why have just one accessory option when you can have two? 

We also adore these princess party hats with tulle embellishments. A must-have for any royal celebration! For more fairytale favorites, check out the rest of our princess party collection here!

4) Admit One Circus Party

Since parenting can sometimes feel like a circus, you might as well clown around. That’s why this party idea is fabulous for any wild one year old! All you really need for this theme is a spread of circus-themed tableware like these lion plates, or this melamine dinner set; and some roaring good decorations.

Circus snacks are also crucial, so we recommend serving some buttery popcorn in classic buckets. Throw in some animal crackers and confetti cake, and you’ll have yourself the ultimate circus celebration! In need of a little more fanfare? Step right up and shop our entire circus party supply collection!

2nd Birthday Party Themes 

Now that we’ve covered the first big milestone, let’s move on to #2! Second birthdays are just as fun, especially since your little one is older and more perceptive of the partying. So without further ado, here are our favorite themes for turning two!

1) Ballerina Two-Two Party

If you have a petite prima ballerina, this idea is tutu perfect for their second birthday party! For decorations, we suggest a balloon garland in various shades of pink. But if you want to keep things simple, this foil ballet slipper balloon is also magnifique.

As for additional accents, we love these pirouette plates layered with these ballerina slipper napkins. And since smashing cake is so one-and-done, we recommend having ballet-themed cupcakes for this 2nd birthday theme. For even more ideas, chassé your way over to our ballerina party blog post, and shop the rest of the collection here.

2) Choo Choo, He's Two! Train Party

All aboard! Here’s another terrific vehicle-themed party idea for any train obsessed two year old. All you really need are some train shaped plates, napkins, and party garlands. (Bonus points if you can throw your party on an actual train!)

If you’re wanting to take a vintage twist on this theme, feel free to try out this adorable DIY! Simply round up some old picture books, then stencil, cut, and hang up any phrase you’d like. We went with the classic “Choo Choo,” but the options are endless.

3) Two The Moon And Back Party

Looking to throw an out-of-this-world 2-year old birthday party? A space-themed celebration is always a guaranteed blast! We recommend decorating with rocketship balloons, moon and star garlands, and all things holographic. 

For a stellar tablescape, set out some space-themed plates, astronaut napkins, and rocket shaped party bags filled with galactic goodies. And if you really want to spoil your little spaceman, shop the rest of our collection of outer space toys and party supplies. 

Those are all the first and second birthday party ideas we have for now, but we’re always keeping an eye out for more inspiration to share. No matter what theme you decide to go with, it’s all about celebrating your kiddos big day with friends and family. Wishing your little one the happiest birthday, and you the best of luck!
