My mom was brought up being told, "Don't hug a crying baby, because you're just teaching them to cry more."

So, I was crying in my crib, and my mom resisting all motherly urges, was letting me be. My dad walked in, asked my mom why she wasn't doing anything, and picked me up. I immediately stopped crying and my mom says she then realized that I just wanted to be loved, and disregarded that bad advice.

YMMV
