Getting Started with First Birthday Decorations
1. Monthly Photo Banner
Creating a clothesline-style display showing baby's growth from month 1 to month 12 provides a beautiful visual timeline. All you need is some twine, mini clothespins, and your monthly milestone photos. When I created this for my daughter's party, the grandparents were visibly moved seeing the transformation from tiny newborn to active almost-toddler all in one display.
To create your own:
String twine or ribbon between two secure points
Print 4×6 photos of each monthly milestone
Use decorative mini clothespins to hang them in order
Pro tip: Add small cards with baby's developmental milestones for each month underneath the photos. Our guests spent considerable time viewing this display and reflecting on how quickly the year had passed.

2. Statement "ONE" Sign
A large decorative "ONE" or "1" creates an effective focal point for your celebration space. For my son's woodsy-themed party, I created one from cardboard letters covered in moss and twinkle lights that became a popular photo opportunity.
There are numerous ways to create this statement piece:
Cardboard letters decorated with tissue paper flowers
Wooden numbers painted in your theme colors
The best part? After the party, these make wonderful decorations for baby's bedroom or playroom. Our "ONE" sign has become a cherished keepsake that evokes wonderful memories.
3. Personalized High Chair Decorations
Decorating your baby's high chair for the smash cake moment significantly enhances photos. I learned this lesson when my first child's cake smash pictures looked rather plain compared to my friend's who had added a simple banner to her high chair.
Some effective high chair decoration ideas include:
Custom fabric banner with baby's name
Tulle skirt tied around the chair legs
Balloon garland attached to the sides or back
Theme-related decorations attached with removable hooks
Ensure everything is securely attached and kept away from curious little hands and the cake itself. Safety should always take precedence over aesthetics.
4. Balloon Arch or Garland
A beautiful balloon display creates a festive atmosphere. For my daughter's rainbow-themed party, we created a balloon arch that became the backdrop for nearly every photo taken that day.
For balloon arch beginners:
Start with balloon clusters tied to fishing line
Use a balloon strip (available online) for easier assembly
Incorporate various sized balloons for visual interest
Add greenery or paper flowers for extra dimension
5. Theme-Specific Backdrop
Creating a simple but impactful backdrop for photos is one of the best decoration investments. For my nephew's dinosaur celebration, my sister created a backdrop with painted butcher paper "mountains" and balloon "clouds" that cost less than $20 but looked professionally designed.
Backdrop ideas suitable for any theme:
Streamers hung vertically from a rod or string
Fabric backdrop with themed elements attached
Paper fan decorations clustered together
Balloon wall in coordinating colors
Position your backdrop where lighting is good and there's adequate space for groups to gather. We learned this lesson after setting up a lovely backdrop in a dark corner that proved impractical. For specific theme inspiration, explore our comprehensive first birthday themes collection.
6. First Year Memory Display
Showcasing special mementos from baby's first year creates a meaningful decoration. For my son's party, I displayed his hospital bracelet, coming home outfit, favorite toy, and first shoes in shadow boxes that later became nursery decorations.
Items ideal for a memory display:
Hospital bracelet or ID card
Ultrasound photo
Special milestone toys
First shoes or baby booties
Favorite books or comfort items
7. Personalized Welcome Sign
A sign at your entrance welcoming guests to "[Baby's Name]'s First Birthday" sets the tone immediately. We placed ours on an easel at the front door, creating the first photo opportunity as families arrived.
Make your welcome sign special by:
Including a recent photo of your one-year-old
Using colors and graphics that match your theme
Adding details like baby's birth date, weight, or special nickname
Incorporating tactile elements like fabric or dimensional decorations
8. Ceiling Installations
Decorating upward with hanging paper lanterns, honeycomb balls, or streamers draws the eye up and makes any space feel more festive. This technique transformed our modest living room into an impressive party venue for under $30.
Easy ceiling decorations include:
Paper lanterns in varying sizes
Streamers twisted and hung from central points
Hanging paper flowers or themed elements
Use removable hooks or tape that won't damage your ceiling. Begin hanging these decorations early, as installation typically takes longer than anticipated.
9. Themed Table Centerpieces
Create centerpieces that reflect your theme using inexpensive elements grouped together. For my daughter's "twinkle twinkle" party, we used mason jars filled with fairy lights and surrounded by gold stars for centerpieces that were enchanting yet economical.
Budget-friendly centerpiece ideas:
Mason jars with themed items and battery-operated lights
Small toys or figurines clustered with decorative elements
Potted plants dressed up with ribbons or themed picks
Photos of baby in decorative frames
The key is grouping similar items together rather than spreading them out. Three small items clustered together always appears more intentional than the same items scattered randomly.
10. Custom Food Labels
This small detail makes a significant impact. Design small tent cards that identify foods with theme-related names. For my son's construction-themed party, we served "Bulldozer Brownies" and "Cement Mixer Mashed Potatoes" identified with construction-themed signs.
Make food labels more effective by:
Using themed graphics that match your invitations
Creating clever names related to your theme
Including allergen information for guests with dietary restrictions
Using holders that enhance your theme (like tiny trucks for a construction party)
11. Photo Prop Station
Setting up a corner with themed props creates an interactive decoration that results in wonderful photos. My DIY photo props made from craft store supplies cost under $20 but provided substantial entertainment.
Recommended props include:
"I'm ONE" signs for baby
Themed hats, masks, or costume pieces
Speech bubbles with playful sayings
Frame cutouts in your theme colors
For even more fun activities, consider incorporating some first birthday games into your photo station.
12. Smash Cake Decorating Station
Create a special decorated area specifically for the cake smash moment. After cleaning up my son following his enthusiastic cake smash, I strongly recommend a washable mat underneath.
Elements for an ideal smash cake area:
Washable floor covering (plastic tablecloth works effectively)
Themed backdrop sized to frame the high chair
Additional lighting for quality photos
Decorative banner or bunting above
Balloon clusters on either side
Consider the timing of your cake smash carefully. We scheduled my daughter's right after her nap when she was in the best mood, which resulted in much happier pictures than my son's less ideal timing. For more creative cake inspiration, browse our first birthday cake ideas.
13. Customized Party Hats
Enhance simple party hats with ribbons, pom-poms, or themed elements. For my daughter's fairy garden party, we added silk flowers and ribbons to basic party hats for a magical touch that was very affordable.
Ways to customize basic party hats:
Add tissue paper fringe or tassels
Glue on themed paper cutouts
Attach ribbons, streamers, or yarn
Paint or cover with decorative paper
I created a special larger hat for the birthday baby and mini versions for stuffed animals placed around the party. These small details added themed decorations throughout the space very economically. If you're planning a magical celebration, our fairy first birthday party guide has even more enchanting ideas.
14. Door or Wall Wreaths
A birthday wreath using tulle, ribbon, or paper flowers announces the celebration. I hung one on our front door to welcome guests and another behind the cake table as additional decor.
Materials that work well for birthday wreaths:
Tulle wrapped around a foam wreath form
Balloon clusters attached to a wire hanger bent into a circle
Artificial flowers attached to a grapevine wreath
Paper pinwheels arranged in a circular pattern
This decoration doubles as a photo opportunity. We captured charming pictures of my son standing next to his birthday wreath, and now we hang it on his door every birthday as a tradition.
15. Custom Fabric Banner
Sew or hot-glue a fabric banner with your child's name or "Happy Birthday" that can be reused for future celebrations. I created a simple triangle pennant banner for my son's first birthday that has appeared at five family birthdays and counting.
Tips for creating a lasting banner:
Use sturdy fabric that won't fray easily
Choose neutral colors that can work for multiple events
Attach pennants to ribbon or twine with enough extra length for hanging
Use fabric paint or iron-on letters for personalization
This is a decoration worth investing more time in since it will be used repeatedly. Our family banner has become a sweet tradition that appears in birthday photos year after year.
16. Balloon-Filled Floor
For a playful touch babies enjoy, create a "balloon pit" by filling a small area with inflated balloons. My daughter's expression when she crawled into this sea of colors was truly delightful.
Safety tips for balloon floors:
Use balloons large enough not to pose choking hazards
Create a contained area using a baby pool or blanket boundaries
Supervise closely at all times
Consider mylar balloons for younger babies
This decoration doubles as entertainment and creates wonderful photo opportunities. Be prepared to chase runaway balloons throughout your home for days afterward.
17. Themed Dessert Table Backdrop
Transform your dessert or cake table with a themed backdrop. For my son's circus party, I used a red and white striped plastic tablecloth as the base and added paper decorations stapled directly to it—simple yet impactful.
Simple backdrop materials include:
Plastic tablecloths in theme colors
Wrapping paper secured to the wall
Balloons taped in a pattern
Paper fans or honeycomb decorations clustered together
Focus your decorating energy on the dessert table, as this is where people gather most and where most photos are taken. If you're limited on time or budget, making this one area spectacular is worthwhile. For dessert-themed celebrations, check out our donut birthday party or sweet one first birthday ideas.
18. Hanging Mobiles
Create hanging decorative elements that tie into your theme. For my daughter's butterfly party, we hung paper butterflies at different heights above the gift table, creating a magical fluttering effect that received many compliments.
Ideas for hanging decorations:
Paper shapes related to your theme (stars, hearts, animals)
Tissue paper pom-poms in varying sizes
Origami elements strung together
Ribbon streamers with themed cutouts attached
The movement of these decorations adds life to your party space. We hung ours from the ceiling using clear fishing line and removable hooks, creating a floating effect that was enchanting yet simple to execute.
19. Light-Up Elements
Add string lights, light-up letters, or LED candles to bring warmth and sparkle to your decorations. These work particularly well for evening parties or to highlight specific decoration areas.
Ways to incorporate lights:
Fairy lights strung around doorways or tables
LED candles in mason jars as table centerpieces
Light-up marquee letters spelling baby's name or age
String lights behind sheer fabric for a glowing backdrop
For my winter baby's "ONEderland" party, we created a magical atmosphere using string lights behind a sheer curtain backdrop. The photos looked enchanting, and the entire setup cost less than $25. If you're planning a winter celebration, our winter onederland first birthday guide has more festive ideas.
20. Custom Table Runners
Create simple table runners using themed fabric, wrapping paper, or even butcher paper that children can draw on. This transforms basic tables into themed surfaces instantly and protects your tables from inevitable spills.
Creative table runner ideas:
Wrapping paper in your theme pattern
Kraft paper with hand-drawn elements
Fabric remnants hemmed or with no-sew tape
Plastic tablecloths cut into runner width
For my son's construction party, we used black bulletin board paper with yellow "road lines" drawn down the middle. We added toy trucks and construction signs for a themed runner that became part of the play experience.
21. Milestone Achievement Display
Create a poster or display highlighting baby's achievements from their first year—first foods, first words, favorite toys, etc. Our guests appreciated reading about my daughter's milestones and comparing notes with their own children's development.
Information to include:
First foods and reactions
Favorite toys and books
Sleeping and eating patterns
Nicknames and personality traits
Physical milestones (rolling, crawling, walking)
I created a simple poster board display with photos illustrating each milestone, though you could also create this digitally and print it poster-size. This decoration doubles as a wonderful keepsake for your baby book.
22. Coordinated Balloon Weights
Instead of standard balloon weights, use items that match your theme. For my daughter's garden party, we tied balloons to small watering cans filled with rice that doubled as take-home favors.
Creative balloon weight ideas:
Toy trucks for construction theme
Small stuffed animals for safari/zoo theme
Wooden blocks painted in theme colors
Mini buckets filled with candy
Small books for storybook theme
This approach turns a functional item into additional themed decoration, and when the items double as favors, you're being efficient with your party budget. Speaking of thoughtful gifts, don't forget to check out our guide to the best first birthday gifts.
23. Thematic Floor Decals
Use removable floor decals to extend your theme to unexpected places. For my son's space-themed party, we created a "moon walking" path with silver circle decals leading from the front door to the party area.
Ways to use floor decorations:
Create a themed pathway to the party space
Add character footprints leading to the bathroom
Place special "stand here" markers for photo opportunities
Add game elements like hopscotch or stepping stones
These unexpected touches delight guests of all ages. Be sure to use removable decals that won't damage your flooring—I learned this lesson through experience with some stubborn adhesive that took hours to remove.
24. Upcycled Baby Item Decorations
Transform outgrown baby items into decorative elements. I strung my daughter's tiny baby shoes and added fairy lights for a sweet garland that evoked nostalgia every time I looked at it.
Baby items ideal for decor upcycling:
Baby shoes hung as a garland
Onesies displayed on a clothesline
Empty baby food jars as votive holders
First teddy bears as centerpieces
Wooden blocks spelling out baby's name
These decorations carry special meaning and create a sentimental touch throughout your party space. It's also a thoughtful way to use items that might otherwise be stored away. Don't forget to complement these decorations with the perfect first birthday outfit for your little one.
25. Interactive Decoration Elements
Create decorations guests can interact with, like a wishing tree where people hang notes, or a fingerprint guest book that becomes a keepsake. Our "advice for the birthday girl" cards became a treasured memento we still read years later.
Interactive decoration ideas:
Wishing tree with tags for guests to write messages
Fingerprint art where guests add "leaves" or "balloons"
Photo booth with props that creates memories
Time capsule box where guests contribute small items
These elements engage your guests while creating meaningful keepsakes. For my son's party, we created a "photo wall" where guests could add Polaroid photos and write messages throughout the event—it served as both decoration and activity.
