All of my kids got used to being bunged in the car and taken to some magical destination…lots of bush and no facilities.
Kids love getting dirty…don’t fret about it, and chuck them in the creek if they get really gross.
As far as sleeping goes, make sure they don’t steal all of the doona…chuck them in the creek if they get out of line.
Open campfires can be a bit tricky…if you make it big enough, the kid won’t be able to get within 4’ of it before getting scorched. It’s a wonderful preventative, but also makes the cooking chore a bit of a problem for you…expect burnt snags and hands, and singed hair. If they DO get burnt, chuck them in the creek.
Don’t forget to pack LOTS of disposable nappies. Whilst adults tend to get a bit ‘bound-up’ (at least for the first few days of camping), little 'uns are more than happy to continue shitting. Lots. More than lots. Babies like to shit. It keeps them happy. If you can’t scrape the shit off, chuck 'em in the creek.
Kids will eat anything that is covered with charcoal or dirt. I think it’s a throwback to our prehistoric past. Just remember to remember this when you get back home to your formica kitchen and your microwave if your kid turns his nose up at your gourmet offering.
Take along a bottle of cider vinegar for the inevitable bull-ant bites and other miscellaneous cuts and scrapes. If the vinegar doesn’t ease the sting, chuck them in the creek.
Also remember that when the toddler says he saw a snake, it was probably a 3" skink that was running-like-hell away from his chubby clutches. It was heading for the creek!
Be prepared for some really bad smells in the car on your way home. It comes from a week of charred sausages and no showering. And the smells are NOT coming from the kid!! Remember, the kid has been in the creek on more occasions than YOU have…you are the one that stinks.
Oh, and keep an eye out for kangawallabats. They’re bastards.
