My children's elder sister died. She was 9. She did it over the summer so they didn't have to miss school. The government and headteachers don't know my children as well as we, her parents, do. Why the fuck should it be up to them to tell if they are 'genuinely grieving'? And guess what, over 3 years on, they still are. In fact, a lot of professionals can tell you that when children sustain a close bereavement, many times, they show this many, many years on. I am in my mid-40s and have friends who lost their sibling or parent in childhood. They still mourn this loss.
