This is the exact reason I didn't want to host a party for DD2 when the only little people she knows are at childcare and I have no way of chasing people for RSVPs when I don't know their names/phone numbers/emails.

Did you put RSVP on there and no date or did you not put RSVP at all?

ATM I get super-excited whenever DD1 gets invited to a party so I RSVP straightaway - that may change when her party scene really ramps up
