Have you spent much time in other cultures? Not everyone lives as we do here. Like in rural China, at 3pm every day you see flocks of grandparents at the school gates as they pick up all the grandkids and usually take care of them most of the time as mum and dad are working 14 hour days, 7 days a week.
I find this whole long convo so very first world. Arguing that a child who's obviously very well looked after, with loving family in a financially privileged home is going to be emotionally scared because her parents like to go out a few nights a week. So very first world.
