My child has a nut allergy. How do I make sure the party knows?
As the host, you put an allergy note on the reply form, so every family tells you what the kitchen must avoid. As a guest, yours arrives with your confirmation rather than as an anxious message the night before.
How do I limit children per family without it feeling rude?
Set the limit on the reply form โ it will not accept more names than you allow โ and state it once in the invitation copy. The rule is in the page, so it never has to be a conversation.
What if plans shift on the morning of the party?
Update the page and every parent who opens the link gets the new plan. Nothing goes stale, because there was never a second copy of the details to chase down.
Do the parents need accounts to reply?
No. A parent opens the link, confirms, names who is coming, ticks the food box, done. The account is yours, as the host, for managing the list.
Can the invite go out on paper cards as well?
Yes โ print the page's QR on a card and it opens the same invitation, with the same reply form feeding the same list. Paper announces; the page carries.
