The Ultimate Party Planning Checklist

Planning a kids birthday party can feel like a lot, especially once you factor in a theme, decorations, food, and a house full of sugar-fueled guests. Here's the week-by-week checklist I use with my own clients (and my own kids' parties) to make sure nothing gets forgotten — and nothing feels rushed at the last minute.

6 Weeks to Go: Choose the Theme

Everything else builds off this decision, so start here. Pick something your child is genuinely excited about right now — dinosaurs, space, puppies, pirates, whatever they can't stop talking about. Browse our full list of party themes for inspiration, or check out our guide to 50+ party themes if you need help narrowing it down.

5 Weeks to Go: Set the Date, Time & Guest List

Lock in the date and send a save-the-date text to close friends and family before their calendars fill up. Start a simple guest list now — you'll need the headcount for invitations, food, and favors later.

4 Weeks to Go: Send Invitations

Whether you're mailing physical invites or sending a digital one, get them out now so guests have time to RSVP. If you're going the DIY route, our printable collection has instant-download invitations that match most of our party themes.

3 Weeks to Go: Order Your Decorations

This is the fun part. Order your cake topper, banners, and garlands now so they have plenty of time to arrive — we recommend ordering 2–3 weeks ahead of your event for shipped items. If you're on a tighter timeline, our printables can be downloaded and printed the same day.

2 Weeks to Go: Plan Food, Cake & Activities

Decide on your menu and place your cake order if you're using a bakery. This is also a good time to plan one or two simple activities or games — you don't need a packed schedule, just enough to keep the energy going between cake and presents.

1 Week to Go: Confirm RSVPs & Prep Favors

Follow up with anyone who hasn't RSVP'd so you have a final headcount. Put together goodie bags or favors now, while you still have a quiet afternoon to do it — trust me, you won't want to be assembling favor bags the morning of.

1–2 Days Before: Set Up What You Can Early

Hang banners and garlands, set out non-perishable decor, and get your tableware organized. Getting the big visual pieces up early means party morning is just about food, final touches, and getting everyone dressed.

Party Day: Enjoy It

Do a final walkthrough, set out the cake and food, and then let go of the checklist. The details matter, but the point of all this planning is so you get to actually be present for the part that counts — watching your kid have the best day.

Frequently Asked Questions

How far in advance should I start planning a kids birthday party?

Six weeks gives you a comfortable amount of time for most home parties. If you're booking a venue, entertainer, or a specialty cake, you may want to start 8–10 weeks out instead.

What's the most important thing to order first?

The theme and decorations. Once you know the theme, invitations, cake design, and even food ideas tend to fall into place much faster.

Can I put together a great party last-minute?

Yes — printable decorations are the best option here since they can be downloaded and printed the same day, no shipping wait required.
