We have 24 3-4 yr olds in a hall and 4 babies (3 x 11m and 1 x 4 m).
There is a bouncy castle and a paddling pool with balls.
Food = pizza, quorn nuggets, veg spring rolls, veg sausage rolls, crisps, grapes, carrot/pepper/cucumber sticks (tbh I'm expecting to bin these, it's more to show I've made an effort re. healthy food!) and garlic bread.
Drinks - Orange, blackcurrant, water
Activity table - fairy cakes, icing tubes and all manner of sprinkles; colouring sheets with pencils & crayons
Games (if they want them - last year they were all v. happy with just the bouncy castle, but DD says she wants games so I've prepared them just in case) - musical islands (it's a pirate/princess party), find the princess, bubble mat stomping. I am loathe to do pass the parcel for 24 kids as it will take forever!
Face painting & wipes
Wine, coke, lemonade and crisps for parents, also milk, coffee, teabags, sugar
Birthday cake & candles
Party bags, balloons
corkscrew/bottle open, cake knife, matches for candles. Tablecloths, plates, cups, napkins.
First aid kit (MIL is a trained first-aider so we're covered there!)
Camera
kitchen sink....?
Seriously, if there's anything glaringly obvious I've missed off the list, please let me know - I know it's probably overkill, but I do like a good bash!
