As a provider, after a term, I would be truly offended by an offer of more money just to keep a family on. It shows to me that they don't respect me or my decisions. I'm sorry you had some bad experiences with this one. As a mother, I would never let it fly for someone showing their frustrations at my child in that manner, much less would I do that to my charges!
I have always been against throwing money at a problem so it goes my way. That's not the way the world works!
Good luck to you.
