To get parents to RSVP for a kids' birthday party, send the invite two to three weeks ahead with a reply-by date one week before the party, and ask only what you need: child's name, attending, siblings, drop-off or staying, allergies. Send it as a direct text or through the class parent channel, not just in a backpack. Follow up once, three days before the deadline, and message the last few parents personally. Plan for one or two surprise siblings. There are always surprise siblings.
Why is it that 22 kids got an invite, 6 parents replied, and you still somehow need to order the pizza by Thursday?
Kids' parties have the worst RSVP rates of almost any event, and it's not because parents are rude. They're juggling school pickups, three other birthday invites the same month and a group chat that pings 80 times a day. Your job is to make replying the easiest thing on their list. This is part of our broader guide on getting any guest to RSVP, tuned for the parent crowd.
When to send and when to ask for replies
| Step | Timing |
|---|---|
| Send invites | 2–3 weeks before the party |
| RSVP deadline | About 1 week before |
| Friendly reminder | 3 days before the deadline |
| Personal follow-up | On the deadline |
| Final numbers to venue | Whenever the venue needs them, usually 3–7 days out |
Sending more than four weeks ahead feels organised but backfires. Parents mentally file it under 'later' and forget. Less than ten days and weekends are already booked.
What to ask parents in the RSVP
Kids' parties need a few questions adult parties don't. Keep it to these:
- Child's name (and parent's name, because 'Leo' might be two different Leos).
- Attending? Yes / No.
- Siblings coming? And how many, if you're allowing it.
- Drop-off or staying? Tells you how many adults to feed.
- Allergies or dietary needs. Non-negotiable for kids.
- Best contact number for the day.
That's it. Everything else, like the gift policy or what to wear, goes on the invite itself, not in the form.
Kids' birthday RSVP wording you can copy
On the invite:
Please RSVP by Saturday, October 10 so we can plan food and party bags. Let us know about any allergies and whether siblings will be joining.
Drop-off party:
This is a drop-off party. Pick-up is at 4pm. Please RSVP by October 10 and share a contact number for the afternoon.
Siblings welcome:
Siblings are very welcome! Please include them in your RSVP so we have enough cake to go around.
Siblings not included (kindly):
Due to space at the venue, we're only able to host invited children this time. Thank you for understanding!
Want more variations for the invite itself, including milestone and theme wording? Our RSVP wording examples cover plenty of tones.
How to get the invite to parents (not just into a backpack)
Paper invites in school bags have a famously short life. They get crumpled, eaten by a lunchbox or found in March. If you're sending paper, back it up digitally.
- Direct text to each parent if you have numbers. Best reply rate by far.
- Class parent group or school app, but only if the whole class is invited. Otherwise, private messages only.
- Email for parents who prefer it.
- A QR code on the paper invite so parents can reply from their phone in seconds.
We've got the exact texts, including the 'you might not have my number' version, in our guide on sending an RSVP link by text or email.
One link that collects every reply in one list saves you from scrolling through texts at 10pm. Eventic's free RSVP page does that: parents reply without an account or app, and you see a live headcount. For most kids' parties it costs nothing, since the first 25 attending guests are free.
Following up with parents who haven't replied
Assume they forgot, not that they're ignoring you. Most did.
Hi! Just checking if Ava can make it to Leo's party on Sunday at 2pm? No worries either way, just finalising numbers for pizza. 😊
On the deadline, for the last few:
Hi Sarah! Ordering food tonight for Sunday. Will Ava be joining us? A quick yes or no is perfect.
If someone still doesn't reply after that, plan as a no, but keep a spare party bag just in case. The Emily Post Institute's advice on guests who don't RSVP lands in the same place: one polite follow-up, then plan with what you know. For a fuller set of scripts, see our guide on chasing non-responders.
Planning the headcount (kids plus grown-ups)
- Count confirmed kids, then add one or two extra for surprise siblings.
- Count staying parents separately. They eat too, and they notice when there's no coffee.
- Make one or two extra party bags. Someone's cousin always appears.
- Check allergies against the menu before ordering, not after.
Special cases: whole-class, joint and venue parties
Whole-class parties. Expect a lower reply rate, because some parents assume a class-wide invite doesn't need a personal answer. Say explicitly on the invite that the venue needs numbers, and plan for a few no-replies to show up anyway.
Joint parties with two birthday kids. Use one RSVP link, not two, or you'll spend the week reconciling lists. Put both kids' names in the event title so parents know it's the same party.
Venue parties (trampoline parks, soft play, bowling). Venues often need numbers and signed waivers ahead of time. Add a line to the invite asking parents to complete the venue's waiver when they RSVP, and check the venue's cut-off date before you set yours.
Whichever kind of party it is, write the RSVP deadline in bold on the invite and repeat it in every reminder. Parents are skimmers by necessity. The date they see three times is the date they remember.
A few kid-party etiquette notes
- If you're inviting most of the class, many schools prefer you invite everyone, or at least all the girls or all the boys. Check your school's policy.
- Don't hand out invites in class if not everyone's invited. Tiny feelings, big consequences.
- Visible guest lists are fun for adult parties but skip them for kids. Nobody needs to see who's not coming.
May your RSVPs come in early, your allergy list stay short, and the sugar crash hold off until everyone's been picked up.
