Tbh I don't know why people are making the "the grandparents will end up raising it" thing an issue - I know loads of people who were raised by their grandparents for a variety of reasons and they've all turned out to be well adjusted adults. Obviously it's not great that two kids had a baby together but clearly if they were both sexually mature at the ages of 11/12/13 then they're, at least biologically speaking, ahead of most kids their age so it's perhaps not surprising that their relationship turned physical. Nobody could have stopped that from happening; did anybody here's parents know when you lost your virginity? I'd guess not...
