I am having a picnic party for i dd who will be 1 on thursday. The party is sunday and i have no idea what to take, there will roughly be 30 adults and 10 children from 1 - 5! How much food do i need and what can do for the children? I am new to this first time mummy!
Thank you x

An umbrella.
Bin liners.
Coffee.
Shade. (I take dh's fishing umbrella)
Wipes.
Picnic rug.

Are you providing ALL the food?
I'd get people to bring offerings if I were you.

i wasn't going to do food for all but best friend said she would do it. so now i am helping her. How can i do coffee?
