Vent away - home childcare business is definitely a learning curve for sure and shoring up your contract and policies to 'prevent' conflict in the future will help to ensure you do not burn out!

I agree with Momof4 once you have a contract that is agreed upon at enrollment STICK TO IT or TERMINATE and make that clear IN the contract - failure to abide by the policies set out within the contract WILL RESULT IN IMMEDIATE TERMINATION ... cause sadly some clients are like 'children' unless the consequences for 'poor behaviour' are clear and consistent they will keep trying to 'get away with stuff'
