How to Plan a Kids’ Birthday Party: Week-by-Week Checklist
A week-by-week plan for a kids’ birthday party: guest numbers, party length, venue, invitations, activities by age, food and the day itself.
A kids’ birthday party goes smoothly when the big decisions are made early and the small jobs are spread over a few weeks. This checklist works back from the party day, with notes on guest numbers, party length, activities by age, food, allergies and party bags.
6 weeks before: decide the basics
Talk to your child about what they would like, then settle these four things.
Guest numbers
A common rule of thumb is to invite the child’s age plus one, so six guests for a 5th birthday. It is a starting point, not a rule. If you invite the whole class, plan for a larger space and more adult helpers. Our guide to how to make a guest list can help you decide.
Party length
- Ages 1-3: about 1 to 1.5 hours, planned around naps.
- Ages 4-6: about 1.5 to 2 hours.
- Ages 7-12: 2 to 3 hours, or an overnight sleepover.
Venue and budget
Choose between a party at home, in a park or at a venue such as an indoor playground, a pool or a climbing center. Venues often include food and hosts, but book early, as weekend slots go quickly. Set a budget that covers the venue, food, cake, decorations and party bags.
4 weeks before: send the invitations
Send invitations three to four weeks ahead and ask for replies a week before the party. Include the start and end time, the address, whether parents should stay, and a request for allergy information. Our kids’ birthday party invitation wording has examples for every age.
- Book any entertainer, such as a magician, face painter or craft leader.
- Order a cake or decide what you will bake.
- Pick a theme if your child wants one. It makes decorations and games easier to choose.
Pick a design, share one link with parents, and see every reply and allergy note in one list. Free to start.
Create your party invitation3 weeks before: plan activities by age
Plan one main activity and a few short games. Children enjoy the party more when they know what is coming next.
- Ages 1-3: free play, bubbles, music and a few toys spread around a safe space. Keep it simple.
- Ages 4-6: classic party games such as musical chairs and freeze dance, a short craft, or a treasure hunt.
- Ages 7-9: a themed activity, such as a science show, sports games, a scavenger hunt or a cooking session.
- Ages 10-12: an outing or a single big activity, such as bowling, laser tag, a movie night or a sleepover.
2 weeks before: food, cake and supplies
- Plan simple food. Sandwiches, pizza, fruit, vegetable sticks and a drink are enough for most children.
- Check the allergy list. Plan the menu around any allergies, and label food if you serve a mix.
- Buy supplies. Plates, cups, napkins, candles, a lighter, trash bags and wipes.
- Plan the party bags. A small toy, a sticker sheet or a slice of cake to take home is plenty.
1 week before: confirm everything
- Send a short reminder to parents who have not replied.
- Confirm times with the venue, entertainer and cake supplier.
- Ask one or two adults to help on the day.
- Make a rainy-day plan for any outdoor party.
- Write a simple running order for the party.
The day before: set up
- Pick up the cake and any fresh food.
- Fill the party bags and label them if you have a mix of ages.
- Put up decorations, and clear a space for coats, shoes and gifts.
- Charge your phone and camera, and set up the music.
Sample schedule for a 2-hour party
| Time | What happens |
|---|---|
| 0:00-0:15 | Guests arrive. Free play or a simple coloring table. |
| 0:15-0:45 | Main activity, such as the entertainer, craft or games. |
| 0:45-1:15 | Food and drinks. |
| 1:15-1:30 | Cake and “Happy Birthday.” |
| 1:30-1:50 | A final game or free play. |
| 1:50-2:00 | Party bags and pickup. |
After the party: thank-you notes
Send thank-you notes within a week or two. Younger children can add a drawing or sign their name, and older children can write a line or two themselves. See our thank-you note wording for examples. For a general checklist that works for any celebration, see our party planning checklist.

- How far in advance should you plan a kids’ birthday party?
- Start about six weeks ahead if you want to book a venue or entertainer. Send invitations three to four weeks before the party. A small party at home can be planned in two to three weeks.
- How many kids should you invite to a birthday party?
- A common rule of thumb is the child’s age plus one. That is only a starting point. Your space, budget and the number of adult helpers matter more.
- How long should a kids’ birthday party last?
- About 1 to 1.5 hours for toddlers, 1.5 to 2 hours for ages 4 to 6, and 2 to 3 hours for older children. Sleepovers usually run from early evening to mid-morning.
- What food should you serve at a kids’ party?
- Keep it simple: sandwiches or pizza, fruit, vegetable sticks, a drink and the cake. Ask about allergies when guests reply and plan the menu around them.
- Do you have to give party bags?
- No. Party bags are a custom, not a rule. A slice of cake to take home, a book or a single small toy is plenty if you want to give something.
