🌸 One Happy Girl Birthday Party Shopping List
Celebrate your little ray of sunshine with groovy pink, orange and yellow! Cheerful smiley faces, playful daisies and retro details bring this “One Happy Girl” first birthday theme to life—from the balloon backdrop to her birthday outfit.
😊 Smiley Face Balloon Garland
Create a cheerful focal point with a pink, orange and yellow smiley balloon garland. Arrange it around your dessert table or photo backdrop, adding cream balloons to soften the brighter colors. Look for a kit with decorating strip and glue dots to help with assembly.
🌸 “One Happy Girl” Birthday Backdrop
Set the scene for sweet family pictures with a groovy “One Happy Girl” backdrop. Smiley faces, daisies and retro waves make a lovely setting behind the birthday cake. Check the dimensions before ordering so it fits your wall or backdrop stand.
🧁 Smiley & Daisy Cake Toppers
Give a simple cake a happy finishing touch with a One Happy Girl cake topper. Repeat the theme across smaller treats with smiley face and daisy cupcake toppers. Remove decorative toppers and picks before serving or starting your baby’s cake smash.
🎈 Pink, Orange & Yellow Balloons
Fill out your garland or brighten the gift table with pink, orange and yellow balloons. Mix different sizes for a playful display, or add a few yellow smiley face foil balloons. Keep balloons, ribbons and broken balloon pieces out of children’s reach.
🍽️ Smiley & Retro Floral Tableware
Bring the happy colors to your food table with One Happy Girl plates, napkins and cups. You can also mix retro daisy tableware with plain yellow accents. Check the included pieces and pack quantities against your guest list.
🌼 Cheerful Groovy Centerpieces
Add personality between serving dishes with smiley face and daisy centerpieces. Retro rainbows and number-one designs also suit the theme. Choose a few statement pieces to keep your display coordinated while leaving room for food and drinks.
🎨 A Happy Little Coloring Corner
For older siblings and cousins, set out flower coloring books, washable jumbo crayons and smiley and daisy stickers. It’s an easy activity for children to enjoy between party moments. Choose age-appropriate supplies and keep small craft pieces away from babies.
🎁 Smiley-Themed Party Favors
Send a little happiness home in One Happy Girl favor bags. For older children, add daisy sunglasses or a sheet of cheerful stickers. Tailor the contents to each guest’s age rather than giving small accessories to babies.
✨ A Warm, Groovy Glow
Add a playful glow to an indoor display with a yellow smiley face LED sign or flower string lights. Position them behind the cake table or on a high shelf, with cords and battery packs secured away from children.
🎀 “One Happy Girl” Birthday Banner
Hang a pink, orange and yellow “One Happy Girl” banner above your dessert table. For a personal touch, look for a custom retro name banner that complements your party colors.
👗 A Happy Birthday Outfit
Get your little birthday girl ready for her moment with a One Happy Girl birthday outfit or a pink or orange daisy dress. Choose soft fabrics and a comfortable fit for crawling, cuddles and photos. Have a spare outfit ready for after the cake smash!
🌸 Daisy Decorating Extras
Tie your setup together with pink, orange and yellow daisy garlands or paper daisy wall decorations. Cluster them around your backdrop or above the party table for extra flower-power charm without taking up serving space.
🌼 Keep it happy and simple: start with a smiley balloon garland, matching tableware and a birthday banner. Repeat pink, orange and yellow throughout your setup, then add a few daisies for a sweet, groovy finish.
