I wont comprimise on anything. I spent a long time thinking about what I wanted to offer, how long I was willing to work and about how much I wanted to be paid, once those decisions were made then that is what I follow. If you bend for one parent will you bend for then next?

To me, contracts are in place to set out rules and expectations of not only the parent but also the provider. If you do not expect the parents to follow your written contract as is, then you should change it.
