One of the reasons I wrote into my contract that I could release if I had had enough of the parent and it didn't just have to be about a child. Have used this after getting notice from a family who then decided to make my life hell for the last three weeks of care and got termed at the end of week 1 for being late, rude, child not having proper stuff for the day etc.

Provider will give at least three weeks written notice should she wish to change or terminate the contract. The provider reserves the right to terminate without notice for breach of the terms and conditions of this contract or if, in the provider’s opinion, the continuation of the child or parent as part of the daycare group is detrimental to the well-being of the other children in care.
