I work with a local charity that works with children (especially girls) from deprived backgrounds to broaden their horizons, think about ways of getting to University and having a career they love (not necessarily high flying, just something they want to do).
It important to these children that they see that work is a way out, to gain independence and not rely on benefits (like so many members of their families).
That is what children should be concentrating on at school, not trying to make decisions about a lifestyle that they may never have - they may not find a partner, they may not have children, they may get married but end up divorced or widowed, they may experience illness.....
I remember when I was 16/17 I was busy making plans to go to Oxford with my then boyfriend, marry, travel the world, have children and then be a politician. At 19 he killed himself. I did go to Oxford, but did a different degree and ended up in health services research - specialising in mental health. At 21 I was diagnosed with cancer and told I would never have children. I did marry and eventually, many years later, had children - but my life is very different to what I thought it was going to be. So you see, you can't make plans about the rest of your life at such a young age.
All we can do is to educate our children to make the best decisions for their own lives and give them the skills needed to adapt to changing situations.
For many children, the rot that Kirstie Allsop and others like her spouts only means that young women are being put in potentially vulnerable positions when the relationships that they have when they are young end and they have no means to support themselves and their children.
Sorry for the essay.
