One of the more important things I've learned being a father:

There will always be whining. You cannot always appease. Choosing your battles is the most important thing. Once you've decided, you have to stand firm. If you change your mind due to whining, you've "let the terrorists win" and you can be assured of one thing; you'll get a lot more whining, because you've shown that it works.
