Camping with a Preschooler and a Crawler.

[Seekrit]

So we're going camping over Christmas, at a powered site at a caravan/camping park on the beach. There's all amenities and a camp kitchen (there'll be access to a stove, a microwave, a fridge..) so it's not too bad for our first camping adventure

Apart from the normal camping stuff (Tent, utensils, food, thongs/crocs for the shower, gas stove, sleeping gear, torches etc) what do I need to remember to put on my list?

Also, what kind of low-storage things should I get for Cobey (who'll be 3.5) for Christmas, that we can easily pack in the car. I'm thinking a kite and some beach games, but what else? :)

Thanks :D
