That is interesting, Emily
However, I do think that 50+ years ago we had to learn resilience also -
There are huge demands made on children to succeed, keep themselves safe, including the first two you mentioned. However, your mention of coping with electronic media and all the pressures that seems to be bringing to young lives is one that we never had to cope with and it is a very large part of their lives today, not a world I look forward to my DGC joining in with, but they will.
There was a lot of pressure on us from the age of about 9 with the 11+ (not something most children encounter today), being resilient and finding a way forward if you 'failed', the pressure of all the exams if you 'passed'. Finding our own way around to and from school whereas today many are taken to and fro by car. There was unkindness and bullying in those days too.
I do think that some of today's children are not learning resilience in their day to day lives as a natural part of growing up, many parents seem to wrap them up in cottonwool. So it will probably do the parents more good (and of course filter down to the children) to attend seminars such as these!
