Unfortunately it's a mixed bag. She'll have a case worker tell her she can do one thing but then the handbooks they give her explicitly forbid it fairly often. They're oftentimes not very knowledgeable about their own rules.

IIRC she can have the children stay at a babysitters house (that hasn't been viewed by CPS or reviewed for suitability) without breaking rules but cannot have a babysitter at her house to watch the kids.

The rules aren't very consistent and I think the majority of people just opt for not following them to the letter, but that's not generally how my mom operates so.
