We should always have open discussions about this kind of stuff.  It's how we grow, learn and get better.

What do you think about "happiest baby"?

My thoughts:  The happiest baby on the block is the one who has a secure attachment to her parents and does not experience undue stress.  This baby never has to "cry it out".
