Fill in the party details, pick a tone, and copy wording that puts the age, the time and the RSVP line where parents actually read them.
[Child] is turning [age]! Join us [date], [time], at [address]. Cake, games and probably some mess. Please let us know by [reply-by date], and tell us about any allergies, at [phone or email].
Fill in the form and the brackets fill themselves.
A parent reading an invitation looks for the age first, then the date and time, then how to reply. The generator keeps that order in every tone, and always asks about allergies, because that is the line hosts most often forget and most need. The full guide to invitation wording has more examples by age and the five mistakes that cause a mess.
