Hardly any RSVPs to myv3 tear holds party

[GrannyandMum]

Can I ask how soon I should get RSVPs to my daughter's 3rd birthday party? Only 5 out of 30 so far. The RSVP date isn't for another week but should I have had more by now or do people wait until nearer the date?
I desperately want her to have a nice party because that's all she has asked for. Any advice would be appreciated.
I don't have any contact numbers for parents.

Five people for a three year old’s party is plenty. She won’t remember it in another couple of years. I’m sure she’ll still have a lovely time though. You’ll probably find people will respond last minute but it is irritating when you’re waiting for an answer.
