I think that testimony is mostly social worker and lawyer words in his mouth. I think that boy was manipulated. And I think he was harmed. But he could very well be just as harmed by a 17 year old cheerleader with a desire to have the first wedding. I am guessing the boy was not nearly as interested in his baby and his parents, mostly his mother who was interested in bringing up her grandchild. And she is being denied. If the baby is not put up for adoption the mother still has the ability to extract child support from the father after she gets out of jail. The boy and the baby are clearly pawns here.
I can only go by the long, detailed text in both the OP and the DailyMail article I linked in post 72, and in neither article did his parents' thoughts, opinions or court testimony appear.
The boy who fathered the child said at her trial that he had thought himself in love with her, and that he was heartbroken not to be allowed by social services to know anything at all about the child including what sex it is.
You are correct that if the pedo-mom had been given the child, there would have been a custody and support determination by the court. I've read of at least one other case where a male child was taken advantage of by an older predator and then sued years later for child support, even though he was a coerced minor.
In this case, the boy testified (and presumably her social media posts were examined as part of her trial) that the skank teacher assured him that she could not become pregnant. She cared nothing about him or the child, when it comes down to it.
