That and also give your info to local providers so they can give to parents that dont have a "back up". I have had so many parents who have no family or friends and really seem to get in a bind when I have to close, drives me up the wall with "guilt", wish I had a quality care taker to refer them to.....great idea! good luck
I also heard of a woman who provided "sick day" care (if providers call in sick or provider wont take child due to "light illness" such as heavy drainage or fever) she called herself "rainy day Day Care" too cute. If you don't mind the germs.
