First Birthday Party Timeline: Month-by-Month Planning Checklist

6 Months Before: Start Your Vision Board

Most Chicago parents start thinking about the first birthday around the six-month mark. You do not need to book anything yet, but this is the time to:

• Decide on a general party style — intimate family gathering or bigger celebration
• Start a guest list draft with rough headcount
• Research party venues and event spaces in your neighborhood if you are not hosting at home
• Set a preliminary budget using our budget planning guide

If you already know you want a summer weekend date, popular venues in neighborhoods like Lincoln Park and Wicker Park book 4-6 months out.

4 Months Before: Lock In Your Date and Venue

This is your first real decision point. Choose your date, confirm your venue, and put down deposits.

• Book your venue or reserve your backyard/home date with family
• Hire a photographer — first birthday specialists fill weekends fast, especially during spring and fall
• Choose your party theme and color palette using our 2026 theme guide
• If you want a cake smash session, book it now — these are separate from the party and need their own date

3 Months Before: Book Your Core Vendors

With the big decisions locked, fill in the vendor lineup:

• Order your birthday cake and smash cake — custom cakes need 4-6 weeks minimum, so ordering at 3 months gives you margin
• Book entertainment if you want a bubble artist, character visit, or musician
• Reserve party rentals — tables, chairs, bounce houses, and tents book quickly on weekends
• Hire a balloon artist for installations or arches

2 Months Before: Invitations and Details

• Send invitations — digital or printed, two months is the sweet spot for RSVPs
• Finalize your menu and book your caterer or plan your DIY spread
• Order party favors and supplies
• Browse custom invitation designers if you want something beyond a template
• Check neighborhood park permit requirements if your party is outdoors

1 Month Before: Confirm Everything

• Reconfirm every vendor booking with dates, times, and addresses
• Collect final RSVPs and update your headcount with the venue and caterer
• Order decorations and styling or start your DIY projects — our DIY decoration guide has ideas that photograph well on any budget
• Plan the party-day timeline: photographer arrival, guest arrival, food, cake, smash cake, gifts
• Buy the birthday outfit and a backup

2 Weeks Before: Backup Plans and Prep

• Prepare a weather backup for outdoor parties — check our indoor venue options if you need a pivot
• Assemble or test any DIY decorations
• Write a shot list for your photographer
• Confirm delivery windows for cake, rentals, and any vendor arrivals
• Prepare a playlist or hire your entertainment for specific time slots

Week Of: Final Countdown

• Do a final vendor check-in with anyone arriving day-of
• Prep the night before: set up decorations, portion favors, lay out outfits
• Pack a party-day bag — extra baby clothes, wipes, snacks, first aid kit, phone charger
• Charge cameras and clear phone storage
• Delegate one task to a family member so you are not running everything solo

Day After: Wrap Up

• Back up all photos and videos immediately
• Send thank-you messages while memories are fresh
• Leave a review for vendors who did great work — it helps the next parent find them
