NN,,times have changed since the 60's/70's and 80's,,where emotions weren't as openly expressed as today.
Years ago,,as long as parents fed,clothed and looked after children to the best of their ability,,it was sufficient and acceptable. Their duties were done. I would say that most were kissed goodnight,then in the morning on their way to school,,and maybe as infants were perched on parents knees while stories were read to them,,as in my own household,,but no outward show of emotion. Children weren't molly-coddled either,,they were taught such things as good manners,courtesy,,good morals.
