My ds will be 6 on the 30th December, so all of his presents come at once, then he has to wait a whole year before getting any more, last year he got so many presents he hardly looked at them, he's also not really into toys and prefers educational toys & books. So I was thinking of asking people to give gift vouchers or money, which I could keep for him to spend in June or July, when he gets fed up with his Christmas presents.
Also how would I word it on the invitation?
