If you really want to get your daycare up and running you may want to offer a small sibling discount. It's really difficult to get started and sometimes you do what you have to do to get those first 5 clients. That being said, in my first year I allowed a sibling discount, but now that I'm established I would never to it again. I agree with the posters who mentioned that it still costs the same to feed all the children so why should you take the cut?
