Well, it was probably the norm (of course they were married) until the last 75 years. Nothing wrong with it biologically and as Stephanie mentions there may be biological benefits. I've seen similar. The problem is that the nature of society has changed. If you want to be successful in today's world, you need an education and a career, usually with both parents working. Sure a teen can go to school (and i think in the US they are still required to) and raise a child, but man is it tough. It's hard enough to go to school and it's hard enough to raise a baby, but put them together and wow. I don't think I would have had the maturity and wherewithall to do both as a teen.
Sure. They have night classes here and probably even special classes specifically for this, at least in large enough cities. I would think they have it in UK.
You're probably thinking of me.

But where's the father in all this? Shouldn't he be helping out, after he gets a good smack across the head with a baseball bat? He needs to be identified and he and his family (if he's under age) should be forced to pay for the upbringing, and that means for the rest of the child's life. And what about the girl's family? Why should "the good law abiding tax payers" be forced to pay for their child's mistake? If I as a kid broke someone's window playing ball, my parents would be responsible for paying for a new window. I would imagine that's the same everywhere. That's no different here.
At what point do you remove the stigma and therefore encourage bad behavior? At what point do you encourage further behavior by making life easy and solving the problems they got themselves into?
I have no sympathy for the girl and certainly not for the swinging dick of a boy/man (and I use the word man loosely) who got themselves into this mess. They and their parents need to foot as much of the cost as possible. But i have immense compasasion for the child and I want to give it its best chance in life. Some sociatal costs will be necessary. And there is no question that I would pay for what it takes for the child than support an abortion.
