DD is 7 on the 3rd of January and is having her party on the 12th - so the Saturday after going back to school.
To give everyone a heads up I sent invites out to her friends the week they broke up for the holidays.
I've had 1 response out of a class of 30 and that was a decline. I know everyone is busy in the run up to Christmas so would I be sensible to send invites again on the Monday she goes back?
