We want those sweet memories to pop in photos and still be fun in real life. It doesn’t have to be expensive—just a little creativity and a sprinkle of “we got this” magic.
DIY Decor Tips On a Mom Budget
When we say “DIY,” we mean stuff we can do during naptime without busting our budget. Streamers are a tiny investment but look way fancier when we layer different colors or twist them across the ceiling.
We can use balloon garlands too—just grab a bag of balloons, some string, and a little patience. No need for a helium tank!
Paper flowers are another win. Grab tissue or crepe paper (the dollar store is our BFF), fold, cut, and fluff.
Pop those flowers on the dessert table or hang them over the entryway. We even like making a number “1” sign with paper plates or cupcake liners glued to cardboard—it’s super easy and looks cute in photos.
Let’s not forget the classic birthday banner. Write out your babe’s name and theme (like “ONEderland” if you’re feeling punny) using colored paper or fabric scraps.
Hang it up with string, and suddenly your living room is party central. It’s the little things, right?
Theme-Friendly Photo Booth Ideas
Every birthday needs a photo booth moment—we all want those “she’s ONE-derful” pics for the ‘gram. For a mermaid or under-the-sea vibe, tape blue and green streamers on the wall and scatter shiny seashells or fish cutouts.
Unicorn party? Snag some sparkly tulle for the backdrop and add a cardboard unicorn horn (it doesn’t have to be perfect, promise).
If you’re going with a princess or fairy theme, try a sheer curtain as the background and toss in some battery fairy lights. Drop in a thrift-store tiara and a few wands for instant glam.
Props make it more fun: cardboard crowns, oversized sunglasses, and a stuffed animal or two always get giggles. For more inspiration, check out 16th birthday decoration ideas—lots of those hacks work for first birthdays, too!
Sweets, Snacks, And Treats That Wow
Let’s be real—the snack table is the star of any first birthday bash during our party planning . Here’s how to serve up treats that look adorable and taste great, while making sure every tiny guest can join the fun.
Smash Cake Styling Tips
A smash cake is the ultimate first birthday rite of passage. We get the urge to go wild, but a few styling tips make it both adorable and parent-approved.
Pick a theme color and keep it simple, incorporating earthy tones for a natural look . Pastel pinks or sparkly gold are classics, but fresh fruit toppings also look amazing.
Want some texture? Try swirls of ombre frosting, polka dots, or even edible glitter. For a super trendy look, use mini bunting or toppers to match the main party theme.
The messier it gets, the more epic your pics—let’s be honest. Use a cake stand for extra “wow” and snap those action shots!
Here’s some styling inspo:
Buttercream ruffles
Sprinkles galore
Whipped cream clouds
Fresh berries
Edible flowers (make sure they’re safe!)
Allergy-Friendly Party Treats
Let’s make sure all our tiny guests—and parents—can snack without worry! Label everything and double-check guest allergies ahead of time. Seriously, you can’t be too careful with this stuff.
For dairy-free and nut-free treats at the first birthday party, we love mini fruit skewers adorned with fresh fruits and other creative ideas . Dairy-free cupcakes or popcorn (for the older kiddos) are always a hit too.
Gluten-free options like rice crispy treats, applesauce pouches, or oat-based cookies usually disappear fast. Kids seem to love them, and honestly, so do a lot of grown-ups.
Check out these easy swaps:

Regular Treat |
Allergy-Friendly Alternative |
