Thank you so much for all of your suggestions. You have all got the brain ticking over again, it seemed to have frozen before.
I like the idea of an afternoon birthday do, and the sausage zizzle idea with telling people to bring a plate and snacks.
This is the first ever birthday I am organising and I know DD isn't really going to know whats going on but I just want to make that effort as after about the age of 6 or 7 I didn't have any special birthdays or anything.
We are still debating where to have it as we can't agree on a venue.
Might sit DP down on the weekend and tell him to either agree with me or I'll just make up my own mind!
