Raising twins pushed me way over to the nature side of nature vs nurture. What works well for one child may be entirely counterproductive for another.

That said, one thing this article really gets right is the importance of not letting your emotions control your mouth and making threats/promises that you can't/won't keep. I also think it's very important that when you screw up while parenting (and you will screw up), that you be sure to take responsibility and apologize to your children. I think a lot of parents think apologizing will make them look weak or diminish their authority, when it's really the opposite.
