It's definitely not as simple as baby is crying pick them up, especially if they have been crying almost non stop for hours at a time, or if you haven't had more than a 1 -2 hrs block of sleep in months and are literally at breaking point or if you are hearing of others around you (your village) that their babies are sleeping for 4/5/8 etc hours a night so what is wrong with my hourly waking baby???
Did you read the blog post? She wasn't referring to those situations.

I find this whole conversation baffling.
