We went to the local park, picked a table next to the playground to put food on, then let the kids run around for a couple of hours. The only "organised" entertainment was a piñata hung from a big tree. I'm afraid I had to put little chocolate Easter eggs in, <ducks rotten tomatoes thrown by super-healthy weaners>

because two of the kids had nut allergies and trying to find healthy snacks with wrappers on which hadn't once been possibly maybe in contact with something nutlike was just impossible. I only put in enough for two for each of the kids, if that makes me less guilty. I figured it was more about getting to batter something with a cricket bat than just grabbing sweets.
For the rest of the food, we had a big pile of seaweed rice crackers (no dips because I didn't have time, but there would have been guacamole and hummus if I had!) carrot and cucumber sticks, homemade pizza slices, and I made a massive amount of Luca's Mum's kuku with spinach which went down a storm. And the chocolate whale shark cake of course. I originally planned to make a big fruit salad too, but there wasn't time, and tbh it didn't really matter in the end. I think if you're going to a party, you're not necessarily expecting to be fed like it's your main meal, and most of the kids are too busy running around like nutters to be that bothered about the food.
For party bags we had the party hats MJ and I had made, a couple of balloons, a piece of birthday cake, a small notepad and a little plastic shark.
