I found it easier to write a general parent handbook with all the policies and info in it.
Then, I have a seperate contract for each family. My contract states the hours and fees for that family as well as brief statements in paying for stat holidays etc.. Basically anything you want to make sure they need to know!! At the end they sign and I sign. They get a copy and a copy stays with me in their file. I'm on a different computer so I don't have access to my contract or I would give more advice. GL!!
