How Do I Choose A First Birthday Theme?
When selecting a first birthday theme, start by thinking about your space, budget, and how much effort you want to put into decorating. The best first birthday theme is simple, visual, and easy to execute. Many parents choose themes based on animals, favorite books, or seasonal ideas, while others reuse their baby shower themes for a more personal touch.

Hang a bumble-bee pinata for any older kids (or even parents) in attendance, and head to Pinterest to find honey-flavored recipes to incorporate into the day. Hiring a sugar cookie artist to make bumblebee cookies can be great favors for your guests, both kids and grown-ups alike!

First Birthday Themes FAQs
What time should a first birthday party be?
Late morning or early afternoon usually works best. This timing helps avoid conflicts with naps and keeps babies and toddlers in a good mood, while still giving guests enough time to enjoy the celebration.
How many guests should you invite to a first birthday?
That depends on your space and preferences, as many parents keep first birthdays small with close friends and family, while others host larger gatherings. Just keep in mind that more guests means more food, seating, and planning, so it’s important to choose a guest list that feels manageable.
Where should you host a first birthday party?
Hosting at home, either indoors or in your backyard, is often the easiest option since your baby is in a familiar environment and you can stick loosely to their routine. Parks, playgrounds, and indoor play spaces are also great choices if you’re inviting a larger group or want a lower-lift setup.
What foods should you serve at a first birthday party?
Simple, finger-friendly foods often work best, as options like mini sandwiches, fruit platters, sliders, and snack boards are easy to prepare and appeal to both kids and adults. Many parents also choose low-effort options like pizza or catering to reduce stress on the day of the party.
Do you need entertainment or games for a first birthday?
Not necessarily. For babies and young toddlers, simple activities like bubbles, music, or a small play area are often enough. If you’re hosting at home, setting up a designated space with toys or sensory activities can help keep little guests entertained without overplanning.
