If the reason is 'only' because of the hours, be prepared for her to say she can change her hours even if you don't think she can. She just may find a relative to drop off or may be able to adjust her work hours so you'd be stuck if you have other issues with her than just hours.
I did give someone a friendly ultimatum one time. I just simply said "I'm so sorry to have to tell you this but if we can't get his no napping under control, I just won't be able to watch him anymore." I think starting off with the "I'm so sorry" relates that it is nothing personal but a business decision.
Good luck!
I agree with Laurel. She will definitely say she's willing to change hours. So make sure you have a comeback if there are other reasons you do not want this family. Good luck!
