I am not a parent. Because of this, I do not dole out parenting advice. I have nieces. I have friends with kids. And I assume that the parents in all of these situations know what they're doing. They know their child, and how to handle them. But, being around them, I have heard them receive parenting advice from others.
While I'm sure that these people mean well, they are pretty much all guilty of spewing out "The 10 most irritating, least helpful parenting tips".
