Dreaming up a “First Trip Around the Sun” first birthday for your baby girl, with a soft boho sunshine vibe to match?
Think dreamy pastels, smiling suns, and the kind of thoughtful little details that have guests asking where you found everything.
Whether you lean all-in on boho or keep things simple and sunny, this guide walks through every piece of the look — cookies, cakes, toppers, and all the extras in between.
🌈 Custom Cookies to Match the Theme
The sugar cookies set the tone for the whole spread — sunshine and rainbow shapes iced in soft pinks and buttery yellows, equal parts sweet and whimsical.
Custom sunshine cookies like these are easy to order on Etsy, and plenty of sellers will personalize them with your baby’s name or a short birthday message.
Feeling crafty instead? Pick up a sun-shaped cookie cutter set and bake and decorate a batch of your own.
Ready-made, individually wrapped cookies are also sold on Amazon if you would rather skip the baking entirely.
Tip: On Etsy, search “First Trip Around the Sun cookies” to find ready-made sets that ship fast.
☀️ Smash Cake + Sunshine Cake Topper
The two-tier cake is the centerpiece of the table — pale lavender frosting, fondant stars scattered over both layers, and a big cheerful sun perched on top that channels pure “You Are My Sunshine” energy.
To recreate the look, pair a sunshine cake topper with a set of edible star decorations.
A pretty pastel cake stand underneath pulls the whole display together.
Pro Tip: Order a plain cake from a local bakery and bring your own topper set — it looks fully custom with half the effort.
🍰 Smiling Sun Cake + Cupcake Ring
One of the cutest details of the whole party? This grinning little sun cake.
It is a single tier with a simple sun face, ringed by matching cupcakes so the whole thing reads as a sunshine halo. Serving could not be easier, and the photos come out adorable.
Pipe on the eyes and mouth with icing, and use pink fondant for the rosy cheeks to copy the face.
Set it out on a white cake board or a pastel cake stand for display.
Bonus Tip: Cupcakes are perfect for little guests — and nobody has to pause the party to slice cake.
🎀 High Chair Banner + Party Poster
The high chair moment is non-negotiable — cake is involved, after all.
The pairing that makes it work is a soft “ONE” banner across the chair with a custom party sign hanging behind it.
A boho “ONE” high chair banner just like the one in the photo is easy to find.
Add a “First Trip Around the Sun” poster behind the chair — framed, or mounted on foam board for a cleaner finish.
🎈 Balloon Garland Magic
A pastel balloon garland lifts the whole room the second it goes up, especially draped over the party table or a photo backdrop.
A peach and pink balloon garland kit includes everything you need to build one, right down to the glue dots and balloon strip.
An inexpensive electric balloon pump also makes inflating everything dramatically faster.
Tip: Hang the garland the night before so party morning is not a scramble.
✨ “First Trip Around the Sun” Party Banner
The hand-painted banner might be the prettiest detail of all for a baby girl’s party — playful and charming, yet simple to hang.
A “First Trip Around the Sun” banner with sun cutouts captures the same feel.
A matching tassel garland or a few hanging sun decorations layered in add even more charm.
🌼 DIY Centerpieces That Pop
Mason jars, white blooms, and a couple of paper toppers — that is the whole formula, and it makes the party tables look seriously cute.
Sunshine cake toppers double beautifully as decorations tucked into the jars.
Pick up a set of mason jars and a bundle of faux white flowers and the setup practically builds itself.
Bonus: Afterward, the centerpieces can go home with guests as favors or double as thank-you table décor.
