I'm not sure that we'd ever truly know who has or has not been kicked out of a daycare before. I wouldn't tolerate behaviour that potentially could damage my house or belongings or be unsafe for the child.
As far as where the normal people are, I've been wondering myself. For the last 2 years I had a great group of kids, and now that several have moved on to school, I can't find normal parents or kids to fill the spots. I've had about 15 parents ask me to change my hours or pricing to suit their needs. That's not gonna fly with me! So I have said no, but it's at a financial loss. I keep telling myself it's better to wait for a good family than sacrifice my contract/policies just for the sake of money. If you can start advertising, then I would. Hopefully you can find a child or family who respects you and your program. Good luck!
