Celebrate your September birthday kid with a knock-out party. Need a party theme? Then you've come to the right place. We've compiled some excellent ideas for their unforgettable bash. No matter which one they choose, they are guaranteed to have a party to remember.

Fall Equinox Party

fall birthday party


Welcome the crisp weather and embrace the changing color leaves with a Fall Equinox party. The first official day of fall is September 22, but no need to wait till then for a fall celebration! Keep the activities outside to enjoy the crisp air and run headfirst into all of the fall activities. Collect all the different color leaves and carve some pumpkins. You can even take the party on the road to an apple orchard and go on an apple overload. Finish off the party with a pumpkin cake topped with fresh cream cheese icing to truly get you in the fall spirit. 

Teddy Bear Party


Kara's Party Ideas

Make your cuddliest dreams come true with a teddy bear birthday bash in honor of National Teddy Bear Day (September 9). Let your guests RSVP "plus one" to include their bear friends, and decorate the party space with super cuddly teddy bears — giant ones included! Set up a teddy-themed craft station where kids can make ears to match their teddy. Or go the extra mile and channel your inner bear with a teddy bear face painting tutorial.

Dream Day Party


Kara's Party Ideas

World Dream Day falls on September 25, so it only makes sense to throw a sweet dream sleepover party to celebrate all of their wildest dreams. Now, this party won't be like a typical sleepover. Go the extra mile and set up individual tents for the kids to spend the night and have your kiddo tell their friends to come dressed in their fanciest PJs. They can spend the night munching on unicorn s'mores, making dream catchers, and sparkly dream jars. Have them finish off the night with a movie marathon in their personal tents so they can fall asleep and dream the night away. 

Superstition Party

September birthday theme ideas


With Friday the 13th falling in September this year, it only makes sense to start the spooky season a little early with a superstitions party. For this theme, the creepier, the better. Fill the room with open umbrellas, fake black cats, and decorate with the number 13 all over the place. Have the kids test their luck and make a superstitions obstacle course: see if they can cross the sidewalk without stepping over any cracks and dodge all of the ladders. Then they can wind down with some cake and read all about the craziest superstitions from around the globe

Batman Party


Hostess With the Mostess

Take the kids to visit Gotham City and celebrate National Batman Day (September 18). Send up the Bat Signal on the invites to let guests know they've been called into action. Then test out their superhero skills, and see who has it in them to help protect Gotham City. Thank can take a break from trying out all superpowers and focus on their superhero suit with a customized cape, just like Batman himself. Have them finish off the day in Gotham with a Batman-themed cake. Want even more ideas for the Batcave? Check out Hostess With The Mostess for some more Gotham-themed inspiration. 

Football Party



Blue 42! Hut, hut, HIKE! help them score a touchdown with their birthday party this year and tackle a football theme to mark the start of football season. Invite guests to wear a jersey from their favorite team. Turn the backyard into a giant tailgating party full of games like cornhole and the bean bag toss. Don't forget the food! Indulge in stadium favorites like hotdogs, wings, and sliders. When they can't take another bite, switch gears and have the kids customize their own football with their favorite colors. Finish off the celebration and give their throwing arms a little bit of a workout and break open a football-shaped pinata.

Fashion Show Party



Oh, hey, New York Fashion Week, sorry we can't make it this year! Instead, we're celebrating a September birthday with a stroll down the runway in the trendiest designs at a fashion show-themed birthday party. Pull together a basket of clothes that all of the kids can choose from. Let everyone mix and match different pieces, and when they have the perfect outfit, hit the runway! Have kids pick out a few of their favorite songs and press play to set the mood for the runway walk. When the show is over, switch gears and have them design some clothing of their own. Take plain t-shirts from the craft store and give them fabric markers, rhinestones, and scissors to transform a simple shirt into a must-have item of the season. 

Shang Chi and the Legend of the Ten Rings Party



Move over, Captain America — there's a new superhero in town! Celebrate the release of the latest Marvel movie and the newest superhero, Shang-Chi, with a party in his honor. Invite party guests over for a mission worthy of Shang-Chi himself. Since Shang-Chi is known for his incredible hand-to-hand combat, kids should brush up on their beginner martial arts moves before they head out. Once they've mastered the basics, they can take their skills to the next level and learn how they can craft their very own version of The Ten Rings

LOL Surprise Doll Party


Mom Trends

Channel their love for the one-of-a-kind dolls and bring them into their special day with a LOL Surprise birthday bash. Open up an at-home salon so kids can try out some of the looks from their favorite dolls. When they're all glammed up, they can jump in the photo booth to capture the moment. While they wait for their turn at the salon, they can head over to the crafts station and design a custom outfit for their favorite doll. To finish off the celebration, channel the inner surprise of the dolls and cut open a pinata cake. They'll be just as excited to see what's inside this cake as what’s in their LOL Surprise Doll package. Head on over to Mom Trends for even more surprising ideas for the party!

Talk Like a Pirate Day Party



Ahoy matey — cheers to ye birthday kid! Quick translation: hello friend, and happy birthday to your birthday kid! In case you didn't get the gist here, we're throwing a pirate party to celebrate National Talk Like A Pirate Day (September 19). Have your child invite their fellow shipmates over for an adventure out on the sea. Before they start treasure hunting, make sure each of the kids has an official pirate name. When they've returned from their adventures at sea, make them walk the plank (don't worry, this is a good thing) and dig in on a treasure chest cake. Don't forget to send the crew home with some good loot! Find more birthday party ideas over at Project Nursery.

Pinata Party


Sally's Baking Addiction

Let's be real — everyone's favorite part of any birthday party is breaking open the pinata. So, why not make the whole party about the pinata? That's exactly what your kid can do do at their pinata-themed party. When their guests arrive, send them over to the crafts station, where they'll get started on making their very own pinata out of paper mache. While their pinata is drying, let them explore the candy station, where they can pick out what they want to put inside their pinata. If they want to be surprised, set aside a few mystery bags for them to choose from. The celebration wouldn't be complete without a cake — a pinata cake, that is. Cut open the cake and watch the candy break free.
