Fatherhood at 12

Does anyone else find it strange that three boys of 12, 16 and 14 quarrel over the fatherhood of a baby born to a 15 years old? They all claim to have slept with her in her bed with the consent of her parents. I just can’t really imagine how the conversation with the parent went:
“Yes dear, he is 16, don’t you think he's too old for you? Why don’t you bring someone younger next time. He may be smaller, too, and will fit in your bed better. Also make sure you don’t use any of these contraceptive. The priest was clear that we must not corrupt your young minds, lest it should put strange ideas in your little heads.”
