8 yr old out burst with chair. Had to quite watching kids due to fear of my daughter possibly getting hurt.?

I would write up a bill showing what items should have been provided and were not. Show on it how much you owe them due to you quitting the babysitting earlier then previously agreed on. Subtract what they owe and present them with the bill. If you owe them more, you should probably refund them (because it was your choice to stop the care, not theirs), otherwise you can ask for the difference or just tell them that you will accept what they still owe instead of the next 3 days of care. Hope this helps. - Sorry it didn't work out, I know that can be frustrating!! Some parents / kids are just hard to work with - probably better that it is over!!
