Currently there is a parenting paradigm of emotionally involved, caring, loving parent-child relationships. This can be reflected in activities like reading to children, spending time in the park, playing with them, singing to them, buying toys and clothe to them, etc.
How modern is this paradigm of parenting? Has research shown some general conclusion about whether the current paradigm is "modern"? (e.g. fostered by the same forces that gave rise to the human rights, officially stamped by the UN in 1948, and the more direct children human rights, stamped by the UN in 1959). I am aware of anecdotal evidence of some upper classes (including nobility and royalty, particularly female) fostering loving parent-child relationships (mostly through literature and history). More broadly, I found this review of a 1976 book on the topic covering "western culture" from Roman times to XIX century, concluding that
the picture revealed here is one of unloving handling of children in the past, when abuse of them far exceeded devoted care.
I have no idea if this +45 years old image still holds (review called this an under-researched area). It would be interesting to know of other cultures and specific historical settings (e.g. ancient Asian cultures, classical antiquity, medieval ages, Mayan empire, tribal societies, ...). Still, anything that helps gets an idea of modern view of the question is welcome.
