A baby's first birthday is more than a celebration—it's a beautiful reflection of a year filled with love, discovery, and growth. At Fun Play, we understand how important this day is for families, and we've helped countless parents throw joyful, stress-free parties in our Los Angeles play spaces. To make planning easier for you, we've created the ultimate first birthday party checklist based on our experience, customer feedback, and expert advice.

Planning a First Birthday Party Checklist — Where to Begin

Before picking up balloons or ordering the cake, take a breath and set a foundation. Your planning a first birthday party checklist should start with three simple questions:

  • What is your budget?
  • How many guests do you expect?
  • What time of day works best for your baby?

Infants and toddlers often have a limited window of time before naps or overstimulation set in. Most families find that mid-morning or early afternoon works best. Once you've decided on timing and scope, the fun really begins.

Venue — Choosing the Right Space

One of the biggest stress-relievers in any checklist for first birthday party celebrations is selecting the right venue. At Fun Play, our birthday packages in Los Angeles offer everything from private party rooms to soft play areas that keep children safe and smiling. By celebrating in a place built for kids, you avoid cleaning the house and stressing about spills.

If you opt for a backyard party or host at home, be sure your first birthday party planning checklist includes:

  • Baby-proofed space for crawlers and new walkers
  • Shaded or indoor area in case of heat or rain
  • Easy parking and diaper-changing facilities for guests

Invitations — Simple and Thoughtful

Your baby's first birthday party checklist should include sending invitations 3–4 weeks in advance. Digital invitations are perfect for busy parents, and they make RSVPs easier to track. Remember to include:

  • Date and time
  • Venue name and address
  • Any specific instructions (bring socks, leave strollers outside, etc.)
  • RSVP deadline

Theme and Decorations — Keep It Playful

While your little one may not remember the decor, it sets the tone for photos and mood. Whether it’s woodland animals, a rainbow theme, or classic pastel balloons, make it simple and cohesive. The first birthday party supplies checklist for decorations might include:

  • Balloons and streamers
  • High chair banner
  • Photo wall or milestone poster
  • Tablecloths and themed plates/cups
  • A "one" cake topper or birthday crown

We always recommend choosing reusable or biodegradable items to keep things eco-conscious.

Entertainment — For Babies and Adults

Fun Play locations are designed to keep little guests happy and safe while giving parents peace of mind. Our colorful indoor playgrounds include slides, obstacle zones, and sensory toys perfect for ages 0–5. We also offer party packages that include a host, face painting, and toddler-friendly games.

If you're hosting at home, your first birthday party supplies checklist should include:

  • A baby play area with soft mats and toys
  • Calm music or a bubble machine
  • A few simple toddler games (rolling balls, peekaboo blankets)
  • Low tables and adult seating

Food — Simple, Healthy, and Kid-Friendly

For most babies, the cake smash is the highlight of the day. For adults and older kids, consider easy finger foods that can be eaten standing up. Keep allergens in mind and label dishes when possible. Ideas for your first birthday party checklist:

  • A small smash cake just for baby
  • Mini sandwiches or sliders
  • Cut fruit and veggie sticks
  • Juice boxes and water
  • Coffee and tea for adults

At Fun Play, our birthday packages include snacks and drinks, and we can recommend trusted local bakeries for allergy-conscious cakes.

Photography — Capture the Moment

Babies grow fast. Hiring a photographer or asking a friend to help with pictures ensures you’re not stuck behind the lens. Include in your first birthday party planning checklist:

  • A mini photo corner with props
  • A list of key shots (cake smash, family photo, grandparents with baby)
  • A backup phone charger or camera battery

Baby's Needs — Don’t Forget the Basics

Among the balloons and snacks, don’t forget your little one’s comfort. A complete baby’s first birthday party checklist includes:

  • A change of clothes (maybe two!)
  • Bibs and wipes for the cake smash
  • Favorite toys or loveys for comfort
  • A quiet area or stroller for naps
  • Snacks or milk

Party Favors — Something Small and Sweet

It’s not necessary, but small take-home gifts are a nice touch. Go for simple items parents will appreciate:

  • Board books
  • Bubbles
  • Baby-safe snacks
  • Reusable stickers or crayons

We often include favor bag options in our birthday packages or connect parents with our preferred vendors.

After the Party — Thank You Notes and Memories

Even if baby can’t sign their name yet, sending a thank-you note (or email) goes a long way. Use a photo from the party and include a short message of appreciation. Your checklist for first birthday party completion might include:

  • Sorting and backing up photos
  • Sending thank-you notes within 2 weeks
  • Storing decorations or donating extras
  • Writing down milestones or funny memories from the day

How to Plan a First Birthday Party Checklist Without Losing Your Mind

Dr. Laura Jana, a pediatrician and author of Heading Home with Your Newborn, reminds parents: "Babies don’t need elaborate parties, but they thrive on love, connection, and playful interaction." That’s why our venues at Fun Play are designed to focus on the child’s experience, while giving adults a chance to relax.

If you're asking yourself how to plan a first birthday party checklist that balances fun and sanity, the answer lies in preparation, flexibility, and a little help from professionals.
