Dealing with this now myself....We had oldest DD's last night, about half the rsvps came through the kids themselves, she is turning 11. Youngest DD's is next week, have gotten one guest initiated RSVP. She's turning 7 and we are having a party at our house. I have one RSVP from school friend's mom, got a yes from the 5 year old neighbor, but nothing from her parents, asked the parent of another kid and she did say yes, one other friend has not RSVPed but has asked me about gifts so I guess that is an RSVP. Last two invitees are school friends, have never met the parents, have not heard a thing yet.
