The best I can do is point at the San people, who are hunter gatherers in the southwest of Africa. Their culture has likely persisted in the same location from the Paleolithic era, because it's so inhospitable there they wouldn't have many people trying to take from them their lands. Their childrearing philosophy is notable for its leniency towards children. "Children have no sense" is the most commonly applied aphorism, and children generally aren't the subjects of corporal punishment.

This is from college classes, but here's a source that basically backs up what I'm saying.http://www.context.org/iclib/ic04/mcelroy/

There were numerous peoples amongst the Native Americans that regarded corporal punishment as a rather obsolete form of parenting, instead allowing more peaceful or inductive forms of punishment. The methods utilized by various cultures amongst the Native Americans included: an apology to each family member, shame and dishonour, ignoring the child for a period of time, and teaching the child the impact of their behaviour on others (typically the wider community).
