Yes, I realise that; friends had children who were 'accident prone' and I've been with them when accidents have happened.
I'm accident prone myself.
However, there is a difference between a bruise, a broken wrist in a healthy, robust child who has good interaction with a parent and these abused children.
But, like Daniel Pelka, starved, beaten and died 9 years ago, this boy was at school. Daniel's teacher knew he was starving but was hoodwinked by the wicked mother.
I could list cases I remember which people will have forgotten but I can never forget.
It happens time and again and lessons are never learned.
