I think it's desperately sad that, as women, we can so easily write off the entire life of a young woman, because she has a child at 17.
It might be easier to go to get a degree and a great job without a child, but it's not impossible to achieve the same things with a child. Should we really be telling young women who find themselves pregnant that their only options are a life on benefits or an abortion? Because, really, I think that's what a lot of this opinion boils down to.
Most generations of working class women had their children early. They still worked, still provided, still had lives. There is no reason at all why a young women today cannot still achieve that, though it must be difficult when faced with such scorn from your own sex.
The truth is life is hard for all women with children, regardless of your age. Very few of us get by entirely independently. Most of us rely on someone else to help out with childcare, with household responsibilities, whether from the state, family or funded privately.
There are benefits to having children young, from a health point of view. I really don't think there is a right age, sometimes the decisions are made for us.
