Thank you all for your input! So far, I have made up a contract, daily report sheets for diaper changings and feedings, a health record sheet, menus, and activity lists. I'll have to update the papers so allergy info is to be written in on each page, though, that's a good idea. I did make a pretty detailed contract (based on the one we signed when we put Cait in her current daycare) which has all manner of detailed drop off times, late policies and fees, etc.
As far as the state goes, I don't have to be licensed to do childcare but I am working toward that. Even though I'm not licensed, I do intend to adhere to the same state standards, e.g. ratios (which is no more than 4 children per adult), meals, bedding, and everything else.
