My mother was born in 1931, she was evacuated but had an awful time and went home, her father died, her mother was pregnant, she lived in Birmingham so spent most of the war in an air raid shelter while houses around her were being bombed, she left school at 14 and went to work. She is the most mentally stable woman I know. Her childhood was crap but she had rules to live by and she was pretty certain what her future held. In short she knew were she was with her life.
Children today have mental health problems because they are confused, they get mixed messages all the time and no clear rules to live their lives by. Half of them have divorced parents which further adds to the confusion, especially when 2 parents are at odds with each other. They are treated like lepers by the majority of the population (policeman told me this week a local woman dialled 999 because there were children doing wheelies on their bikes in her road - give me strength!!!) They are under so much pressure at school to achieve the teachers targets that learning has stopped being fun they are harrassed through lessons each day and if they get behind they don't get a chance to catch up. Add to that peer pressure from other kids, they can't play outside anymore and every news story is some horror story to do with a kidand it makes for a stressful time. I think the statistic is rubbish but I do think that mentally children are not as healthy anymore.
