Planning a First Birthday Bash party for a 1–1 year old? One whole trip around the sun. Below is a ready-made shopping list — decorations, cake toppers, balloons, tableware, outfit pieces, and party favors — plus everything you need to send invites, track RSVPs, and see who's bringing what, all from one link.

What age is a First Birthday Bash party best for?
This theme works well for ages 1–1. A milestone first birthday with a smash cake, a 'ONE-derful' banner, and keepsake decor for the photos you'll look back on forever.
How many kids should I invite?
A common rule of thumb for younger kids is one guest per year of age — so around 2 guests works well here. For a bigger celebration, this theme scales comfortably to a larger group too.
What's included in this list?
7 items covering decorations, cake toppers, balloons, tableware, outfit pieces, and party favors, each with a ready-made Amazon search link so you don't have to hunt for products yourself.
Can I customize the list?
Yes — add, remove, or swap any item inside Party Planner, then layer on an RSVP page and a gift registry for the same party without starting over.
