PTP - It always astonished me that the same people who could not believe that babies understood object permenence would ascribe sinister motives to a baby's cry.

What I do think is helpful, though, is acknowleging that some babies are 'harder'than others (for whatever reason). Any babies can leave you exhausted but some just take every ounce of energy you have and still want more. It's not the baby being malicious. Mothers experiencing that will have plenty of people telling them it is their fault, and they need to know that it isn't becaue they are bad mothers.

FWIW, I think those babies grow up to be the most fun children, but then I'm a bit biased smile
