With a clear budget in place, you can stay in control while still making the party magical.
- Book 4–6 weeks ahead, or even earlier for popular names
- Entertainment or performers
- Food and drink for children (and possibly parents)

Smart Spending: Mix and match your splurges. DIY where possible, and look for bundled deals from venues or entertainers.
Step 6 – Build a Timeline to Keep Everything on Track
One of the easiest ways to stay on top of how to plan a children’s party is to spread tasks out over several weeks.
- 8–6 weeks before: Choose a date and time that works for your family and book your venue, especially if you're aiming for one of the more popular locations. It's also a good time to settle on a party theme and start researching entertainers so you’re not left scrambling.
- 5–4 weeks before: Send invitations, whether printed or digital, and confirm your chosen entertainer. Begin planning food options and think about your decorations. If you’re making party bags, gather the items you’ll include.
- 3–2 weeks before: Follow up on RSVPs and finalize your guest list. Decide on the birthday cake, whether baking it yourself or ordering one. Ask any friends or family to help on the day, and begin working out your activity schedule.
- 1 week before: Do a final supply shop, prepare party bags, and check your decorations are ready to go. Confirm all the logistics with your venue and entertainer to avoid last-minute surprises.
- The night before: Pack a box with essentials like candles, matches, bin bags, wipes, and plasters. Review your party checklist to make sure you're all set.
Step 7 – Plan the Activities & Entertainment Schedule
No matter the size of your guest list, having a rough plan for activities can help the day flow smoothly.
Activity Ideas by Age Group
- Kids 3 to 5: For ages 3 to 5, keep things simple and sensory. Storytime corners, bubble machines, musical statues, or a themed craft table work well. A puppet show or a sing-along entertainer is also likely to be a big hit.
- Kids 6 to 8: Children aged 6 to 8 often enjoy more interactive games and creative challenges. Think treasure hunts, mini obstacle courses, or team-based party games. Face painting or a magician fits beautifully at this age.
- Kids 9 to 10: For those aged 9 to 10, you can go a little more adventurous. Karaoke, dance-offs, slime-making, or even a mini quiz based on their favourite TV shows make brilliant children’s birthday party ideas for this age group. At-home discos or party games with prizes work well too.
Pro Tip: Allow space for free play or low-key activities. Have a loose structure, a welcome activity, followed by the main entertainment, then food, and finally cake and wind-down games. The best parties strike a balance between energy and ease.
