Dee, I can emphasize with the children having low self-esteem from bad parenting. I've been there. Which is why I'm glad you are available to be their friend.

I wonder if the children wouldn't mind going to church with you so that they can encounter other heartfelt folk and make friends that would help you keep a mindful eye on them? Perhaps they could join a Bible study or youth group that would allow them an outlet to meet others of the same age and better roll models. Also, an escape from their abusive parents.

I'm glad you are there for these lovely children.
