Wondering what type of theme would work well for your twins 1st birthday party? We know this is an exciting time, so read on for a round-up of 10 of the best twins’ first birthday themes!
A child’s 1st birthday party is a big deal, and doubly so when you have twins. You’ve made it through the 1st year, which is always the toughest, as you are becoming more accustomed to parenthood and meeting the needs of not one but two babies.
Twins can be a handful, but they can also make things more fun just because there are two of them.
Below are some exciting themes to consider for your twins’ 1st birthday party. They may not remember the party or the theme, but they will make for great photos and memories of your own as you celebrate making it through that totally bananas first year of twin parenthood!
1. “It was a magical ONE” (unicorns and dragons)
This is a timeless theme that works great whether you’ve got boy-boy, girl-girl, or boy-girl twins! You can get fun and whimsical with the “magic” theme and use unicorns and dragons for outfit, dessert, and decor inspiration.
- Cake idea: in the shape of a unicorn head or dragon egg
- Snack/party favor ideas: unicorn snack mix (with iced animal crackers, whimsical sprinkles, pretzels, and more), dragon and unicorn tattoos
2. “What a year, what a pair!” (famous dynamic character duos)
For all you pop culture fans out there, you can’t go wrong with a classic character-themed party. Dress your twins as character duos like:
- Mario and Luigi
- Mickey and Minnie Mouse
- Dora and Diego
- Thing One and Thing Two
- Phil and Lil (from Rugrats)
- Lilo and Stitch!
- Mike and Sully (or Sully and Boo)
- Harry and Hermione
The pairings are pretty much endless here! You can even get your guests in on the fun by having them come in character too!
3. “Welcome to our circus!”
A circus theme is all-encompassing, with numerous activities built right into the concept. Plus, raising twins really is a circus most days, so it’s more than fitting! You can go as big or as small as you want with this idea.
Hire an animal trainer to come to the party, rent a tent, invite a clown, or have guests make their own cotton candy. Your kids could be dressed as a lion tamer and a lion or two goofy clowns. The options are endless.
4. “You can’t have ONE without the other” (milk and cookies)
This theme leaves room for some creativity but also doesn’t have to be over-the-top if you want a theme that’s on the simpler side. Stick with milk and cookies as your decor inspiration or go with another “you can’t have one without the other” option (like peanut butter and jelly).
5. “These two are o-fish-ally ONE!”
If you want a theme that highlights that your twinnies are a full year old, this is a fabulous option that works for the whole gamut of twin combos (boy-boy, girl-girl, boy-girl).
You can use Swedish fish and gold fish for party snacks (or that how-many-are-in-the-jar guessing game). Plus, fish and all the associated ocean creatures can make for a super colorful aesthetic for any party!
Got twins? Us too! The Twiniversity Podcast with Natalie Diaz was created BY parents of twins FOR parents of twins, from your pregnancy days through your twin’s teenage years, this podcast covers it all. It’s all about parenting twins, offering plenty of strategies for making life better, parenting hacks, and, of course, humor. We are laughing WITH you every step of the way.
6. “Girls just wanna be one!”
If you have girl twins, this could be an adorable theme to guide your party planning. And of course, be sure to add Cyndi Lauper’s “Girls Just Wanna Have Fun” to your party playlist!
7. One prickly pair (or our prickly pair is one)
If you’re leaning towards one that’s clearly made for TWINS, this may be the theme for you. Cactus decor is super easy to find, and twins can sure make things rather “prickly,” so this theme says it all!
8. Pancakes and pajamas (or pizza and pajamas)
This is a fun yet simple and low-key theme that you can get creative with! Have your twins and guests dress in cozy pajamas and serve an assortment of pancakes like blueberry, chocolate chip, and more. This would make for a great morning or brunch birthday party to celebrate your double stack. And don’t forget the coffee, of course!
Or if you want to do more of an afternoon/evening shindig, go with pizza and pajamas instead.
9. 1 year with our 2 peas in a pod
Your little ones have been two peas in a pod since before they were born. They go everywhere together, and even when they started crawling, they were always right next to each other.
Continue the theme of their lives as the theme for their 1st birthday party. You can dress them all in green, and bring tie-in decorative items into play.
10. “Look whooooo’s 1! (owl-themed)
This is a great gender-neutral first birthday theme for twins to celebrate you and your twins being one year wiser! You can use plenty of natural DIY decorations (think: pinecones, flowers, etc.) or use the owl theme to guide your outfit and dessert choices. So many possibilities with this one!
Let your imagination roll with these party themes. All of them can become more extravagant if you’re looking to make a big impression on guests or can be simplified depending on your budget and the size of your RSVP list.
