Theme and Budget
Set a total party budget and stick to it
A great kids party does not require a huge budget. $150-300 covers a solid home party; $300-600 covers a venue party. Allocate roughly: 40% food, 20% activities/entertainment, 15% decorations, 15% favors, 10% invitations and extras. Track spending in a simple spreadsheet or notes app.
Decide on a total budget amount
Break the budget into categories: food, decorations, activities, favors
Let the birthday child choose a theme (with gentle guardrails)
Give 3-4 options that fit your budget and energy level. Broad themes (space, ocean, jungle, rainbow) are easier and cheaper to execute than character-specific themes that require licensed products. A color scheme works as a theme: all-pink, black-and-gold, or rainbow.
Decide between a home party and a venue party
Home parties cost less and give you full control, but require more setup and cleanup. Venue parties (trampoline parks, bowling alleys, art studios) cost more but include staff, activities, and cleanup. For groups over 15 kids, a venue usually reduces your stress significantly.
Guest List and Invitations
Finalize the guest list with your child
A good rule of thumb: invite the same number of kids as the child's age, plus 2-3. A 6-year-old's party with 8-9 kids is very manageable. Expect about 70% to attend. If inviting classmates, check the school's policy — some schools require inviting the entire class or not distributing invitations at school.
Send invitations 3-4 weeks before the party
Include date, time, location, RSVP deadline, and any special instructions
Ask about food allergies and dietary restrictions on the RSVP
Specify drop-off and pickup expectations (stay or leave)
Follow up with non-responders 1 week before the party
About 30% of parents will not RSVP no matter what. A quick text — 'Just confirming the headcount for Saturday — can Max make it?' — gets a faster response than a formal reminder. You need an accurate headcount for food, favors, and seating.
Food and Cake
Plan a simple menu that kids will actually eat
Pizza, chicken nuggets, mac and cheese, and fruit are universally loved by children ages 3-10. Serve food 45-60 minutes into the party — kids who arrive hungry get cranky fast. Skip the elaborate themed food; it takes hours to make and kids do not care.
Choose 2 main food items and 2 sides
Buy juice boxes, water bottles, and one non-sugary drink option
Order or bake the cake at least 1 week ahead
If ordering from a bakery, place the order 2 weeks before. A sheet cake from a grocery store bakery feeds 20-24 kids for $25-40. Cupcakes are easier to serve and eliminate the need for plates and forks. For allergy-safe options, check with the bakery about nut-free and dairy-free selections.
Account for food allergies reported on RSVPs
Prepare allergen-free alternatives for children with dietary needs
Label food items with common allergens (nuts, dairy, gluten)
Buy plates, cups, napkins, and utensils
Buy 20% more supplies than your headcount — spills and double-servings happen. Themed paper goods are the easiest way to carry the party theme without expensive decorations. Solid-color goods from a party supply store cost half the price of character-themed ones.
Activities and Entertainment
Plan 3-4 activities that fill 90 minutes total
The ideal party for kids ages 4-8 lasts 2 hours. Subtract 30 minutes for food and cake, leaving 90 minutes for activities. Plan more activities than you think you need — some fall flat and you need backups. Free play in a backyard counts as an activity for younger kids.
Choose 1 active game (relay race, freeze dance, obstacle course)
Choose 1 craft or creative activity (decorate a cookie, make a bracelet)
Choose 1 group game (musical chairs, scavenger hunt, piñata)
Prepare all activity materials and supplies in advance
Buy and test all craft supplies 1 week before the party
Set up game stations the morning of the party
Plan a backup indoor activity in case of bad weather (for outdoor parties)
Have a plan for early arrivals and the first 15 minutes
Guests trickle in over 15-20 minutes. Set up a free-play activity that kids can join as they arrive: coloring sheets, a ball pit, building blocks, or sidewalk chalk. Structured games work best when the full group is present.
Decorations and Favors
Buy decorations that match the theme or color scheme
Balloons (the single highest-impact decoration per dollar)
A banner or sign with the child's name and age
A tablecloth in the theme color
Assemble party favor bags
Keep favors simple and useful: a small toy, a pack of stickers, a few pieces of candy, and a small activity (mini coloring book, playdough). Spend $3-5 per bag. Skip the cheap plastic toys that break on the car ride home — parents will thank you silently.
Buy or make 3-4 extra favor bags beyond the guest count
Include a leftover piece of cake or cupcake if space allows
Day-of Timeline
Set up decorations, food stations, and activity areas 2 hours before the party
Recruit one other adult to help set up while you handle food prep. Blow up balloons last (they deflate over hours). Put up a balloon arch or cluster at the entrance so arriving guests feel the excitement immediately.
Assign roles to 2-3 helping adults
One adult runs games and activities
One adult manages food, drinks, and cake service
One adult handles photos and greeting arriving guests
Follow the party timeline: arrive, play, eat, cake, more play, favors, pickup
0-15 min: free play arrival activity. 15-45 min: structured games. 45-75 min: food and cake (sing happy birthday, open presents if doing so). 75-105 min: last activity or free play. 105-120 min: hand out favors, say goodbye, pickup. Print this timeline and tape it to the fridge.
Take a group photo and a photo of the birthday child with the cake
Write down who gave which gift as presents are opened
Assign a helper to jot down 'gift — giver' as each present is opened. This list is the only way you will manage thank-you notes later. If you skip opening presents at the party (less stressful for everyone), note them at home as your child opens each one.
Send thank-you messages within 1 week
Frequently Asked Questions
How many kids should you invite to a birthday party based on age?
A common guideline is to invite the same number of children as the birthday child's age, plus one. So a 5-year-old would have 6 guests. For toddlers (1-3), keep it to 4-6 kids since they need more adult supervision. For ages 8-12, kids can handle larger groups of 10-15. Remember that about 70-80% of invited children typically attend, so factor that into your planning.
How much does an average kids birthday party cost?
A home-hosted party typically costs $100-$300 total, covering food, decorations, cake, and basic party favors. Venue-based parties (trampoline parks, bowling alleys, art studios) average $250-$600 for 10-15 kids, with most packages including a party host, food, and a private room for 90-120 minutes. Character entertainers or bounce house rentals add $150-$400 to a home party.
How far in advance should you send birthday party invitations?
Send invitations 3-4 weeks before the party date, and set the RSVP deadline for 1 week before the event. For parties during busy seasons (summer, December), send them 5-6 weeks ahead. Digital invitations through platforms like Evite or Paperless Post are free and make tracking RSVPs much easier. Always follow up personally with anyone who hasn't responded 3-4 days after the RSVP deadline.
What food should you serve at a children's birthday party?
Stick to crowd-pleasers: pizza (budget 2-3 slices per child), chicken nuggets, fruit kabobs, and veggie cups with ranch dip. Always ask about food allergies on the invitation. For the cake, a standard sheet cake from a grocery bakery feeds 24-30 kids for $25-$40 and is often a safer bet than elaborate custom cakes. Serve water and juice boxes rather than soda — most parents of younger kids prefer it.
What are good birthday party activities for mixed age groups?
Craft stations work for ages 3-12 since kids can work at their own level — think decorating picture frames, painting rocks, or making friendship bracelets. A scavenger hunt with picture clues lets younger kids participate alongside older ones. Bubble stations, sidewalk chalk areas, and freeze dance are virtually universal crowd-pleasers. Plan 3-4 activities for a 2-hour party, budgeting 15-20 minutes each.
