We are very CC. I meet our girl's needs immediately, but do it matter-of-factly and without a fuss. She cries some, but like Mama_Meme said, it's developmental stuff, and how they communicate.
I read something in Our Babies, Ourselves that stuck with me: There was an informal study done in Africa in which mothers labeled their babies "difficult," meaning they tended to cry lots and were really vocal about their needs, or "easy," meaning they were fairly quiet and generally seemed more content. Months later, after a time of famine, nearly all of the "difficult" babies survived. Sadly, few of the "easy" babies did. This was presumably because the babies who cried were more aggressive in getting their needs met. (The number of mothers and children was low, so the study wasn't a good qualitative sample, but I think it's useful.)
When my daughter cries, I still remind myself, She is so full of life--she just really, really wants to live!
