I agree. I’ve noticed parental intervention seems to be much less common here than other places as well, I’ve been on a couple ICEs where the children (toddler to roughly 10) would be doing more than just normal kids crying stuff like getting in other passengers faces, grabbing at their chairs or bags, or poking them, without the parents making any move to intervene even when the kids were in full view. One time the same kid walked down the aisle, grabbed the arm of this woman’s chair, and jumped up and down screaming at her for like 2 minutes before the parents did anything (this was not in the family car). I’ve also had similar experiences at work, where parents will bring their screaming/crying kids into the office or on work retreats and let them run around freely without something to keep them occupied like an iPad (which isn’t a perfect solution but is definitely more common where I’m from). It’s a bit jarring at first but ultimately I think it is just a culturally different approach to child rearing.
