I never took it literally, either! I took it more as babies aren't left to cry themselves to quietness and weren't expected to self-soothe, made to wait 3 hours to be fed etc.
Agreed. All babies cry, it's how they communicate their needs.

I can see though, how that article might give false expectations of a perfectly happy baby who never cries for no reason... and some babies are more disposed to crying than others. So if you've done everything 'right' (and TBH, probably half killed yourself in the process given all the conflicting advice out there) what is left to do when your baby still cries?
