Temper Tantrums

I'm a big fan of taking stuff away from the kid when she doesn't ask for it politely. Putting something they want up on a shelf where they can see it, but can't get to it, is handy variation on that theme. To some parents, this will seem like torturous manipulativeness, and guess what? It is. One of your jobs as a parent is to help your kid grow up into the kind of person that other people can stand to be around...
