If you don't receive an RSVP, do you assume they will come or that they won't?

DD's party was last Saturday - invitations had been issued through the nursery (who might have messed it up a bit). Out of 24 invitations, 7 didn't reply at all and none of those turned up. If I'd assumed this would happen, I would have invited more of dd's nursery class but was too scared of having too many at the party (local softplay centre with a maximum of 25 kids).

Maybe next time I'll say "If you don't RSVP, we'll assume you're not coming". Would that seem rude?

I would have assumed they won't come but I wouldn't have invited extra on the back of it - just in case.

I don't think it is rude to put something on the invite - people would probably be grateful that they don't have to bother replying unless their DC wants to go.

I would have asked them to check if they were able to come, I think - but haven't been in the same situation yet (re. children's parties), only parties I have had where the numbers matter.

I don't think the idea is rude or wrong, but perhaps the wording could be less abrupt?
