I'll bet the Ezzo method explains this experience.

Several years ago, I worked with a missionary couple who had come back to the
US from Africa to have their first child.  The baby had some difficulty
attaching, required a lot of calming during the attemps to get feedings
going, and, in the process, the parents and I talked a good bit.  (In
retrospect, probably I talked more than I listened.)  In light of this baby's
tendency to fuss, I was at some pains to model soothing behaviors and discuss
the importance of meeting an infant's needs promptly in the early months so
that he would be a secure and confident child later.  They were very pleasant
and, I thought, pretty receptive.  They certainly didn't challange me
directly.

At that time, we were sending all our breastfeeding clients a survey six
months after delivery.  Responses were anonymous, but it was easy to spot
theirs, as it was postmarked from Africa.  The mother's comments were fairly
scathing.  She thought it was abominable that we encouraged demand feeding,
as that caused children to be selfish and...well, demanding, I guess.  She
said she had *never* fed her son during the night, from the time she left the
hospital, and always fed him on a strict schedule during the day.  I was
appalled at the time, as I could imagine that rather "high-needs" baby crying
and hungry, alone in the dark, night after night, but I had no idea she was
following some sort of "method."  I just attributed it to parents with
authoritarian  personalities. How sad.
