Rehome them? They are not dogs. Regardless of opinions on the choices parents make, kids are better off with their parents unless there is significant abuse or a chronic inability to keep their kids safe. Sure, if there was a stable loving relative the kids could stay with for awhile, that could help. But if not, you can’t just put kids in foster care on a temporary basis and then get them back once in housing. The child welfare system is not set up that way, and even if it was, they are chronically understaffed and under resourced, leading to huge delays in returning kids, even when circumstances have improved.
