Reading the article, the baby wasn't planned, and they didn't think it was a great idea and so decided to conceive - they found out at 12w, and then decided that it would be a great idea to keep the baby rather than terminate. I'm not sure about the 'great idea' bit, but you have to respect their decision not to run away and take the easiest option, even if they didn't really know what they were letting themselves in for.
I think we should feel sorry for everyone involved. Yeah, the girl may have known better - but to have been going out with a boy 2-3 years younger than herself and only 4' tall in the first place, she must have some serious security/self-esteem issues and possibly many more difficulties. 15 year old girls just don't go out with 12/13 year old boys, or at least, not ones who look about 8. She doesn't exactly look like the worldly-wise seductress type so I suspect the whole relationship was more to do with wanting to be loved and needed - but she was looking for the wrong kind, in the wrong place. Poor kids. At least it sounds as though their families are supporting them now - though it also sounds like they could have done with a bit more family support earlier in their childhoods.
