What to put in a contract???

Unfortunately, I don't really think I would be able to "post" anything, either. Sorry!
But to answer some of your questions;
Personally, as a private dayhome, I don't really bank on my agreements with parents being totally legal and binding. It may be different in other areas, and for sure if you are working with an agency. But myself, I go through my policies, etc and really it's just a trust thing with the parents. In the same way, they are trusting that I will not shut my doors on them without notice, and that I am treating and caring for thier child(ren) the way I explain things to them at the beginning.
I do, however, get payment for care in advance. This is standard where I am, and ensures that someone doesn't bail on me and leave me hanging for payment. Really, once I have provided the childcare, I have no recourse to get that money should they leave. It would make no financial sense to take them to court over it, I would probably spend more money doing so! If you have concerns about someone from the beginning, and are worried that they will stiff you somehow, maybe it is not the best working relationship? I will not work with a family that I don't like and trust fairly quickly, and I assume that parents are the same way!
I don't know where you are located, but we have a fantastic service that we pay less than $30 a month for called Pre-Paid Legal. We have ours through Primerica Financial Services, if there is an office near you I would recommend calling to ask about it. You get great access to reputable law firms for a significant discount (sometimes free!) should you ever need it. We have used ours while selling a home, buying a home, when we had contract issues, and so on. Check it out!
