Kids having kids

I was wondering what everyone thought of the 12 year old and the 14 year old having a baby. After finding out that the father was not the 12 year old boy, he said he was devastated. I just don't quite understand how at that age you could really understand fully about what it would be like to have this happen. The parents of the girl even admitted that they allowed them to have sleep overs and everything because she was using birth control. I'm not sure why but I completely disagree with that. It seems wrong to allow kids at that age to do this. Maybe it is because I come from a really strict family. Any thoughts?
