Just read yet another post when inappropriate behaviour in a teen is put down to delayed trauma from covid times.
Having worked as a teacher in many countries, I can tell you that the conditions we called "lock down" are normal life for many of the world's children, and our children are incredibly privileged compared to most.
They didn't really suffer, they just had a slightly less ultra-privileged life for a short time. They were not more isolated and deprived than "normal" they were less isolated and deprived than normal, in a world wide sense - they were just more isolated and deprived than we have come to expect in our wealthy world.
Some may have been afraid, or bereaved, but most were not, and many enjoyed themselves enormously, more children I know preferred lock down to normal school, than preferred normal school to lockdown - and I have asked literally hundreds of children!
Can we stop telling them they are disadvantaged and traumatised now please!
