Honestly? I just treat children the same way I do the dogs. It's not a matter of 'I hope they listen to me' it's 'You'll listen to me or I'll flip you on your ear and stare you down till you do what I want'.
There's usually less flipping involved with the children, luckily, but the method still works.
Although, I'm awesome with animals, so that might not be the best teaching method.

"Now teach them to sit and shake!:D"
If they're anything like my mother, it doesn't matter how many times she sees my baby turn into a giant puddle of snuggly goo, she still won't believe he'll listen to her. So, of course, he doesn't.
