Surely to god she'd be taken into care? She can't still be there, with the family, can she? Poor, poor child
I don’t know anything about the US foster system or when the state takes the child away.
But taking an Amish child into care would probably present difficulties due to cultural differences. They would not be cooperating with authorities and instead continue to make empty promises to handle the matter through their local leadership.
She may not speak English well, and may not be familiar with ‘English’ customs and lifestyles. By now, she would be out of school as they usually leave around 13.
Honestly I’d fear for her living as an unwed mother in that community. But the reality is she’d also have great difficulty living outside her community as well. Hopefully she could have a real choice about her own future.
