Nobody puts Baby in a corner (campsite!)

First time primitive camping with an 18 month old and a six year old.  Tips? Troubles?  Mama has done the alone-in-the-woods-with-a-mechanical-pencil-and-some-rubbing-alcohol type stuff, but I've never done it with the kids.  I find myself somewhat trepidatious, even though I have decent wilderness skills.  I've never had to use them with the kids, though, and well... Accidentally Mommy would prefer not to rock the boat and end up Accidentally Needing Them.

Please... discuss in comments!  I'm sure everyone has an anecdote if nothing else, of their own.
