Some ideas:

You are in it for the long haul? (Or at least have been, I think I remember you saying that you were going back to school...) Regardless, play up your experience. "Established in home daycare providing experienced, reliable and high quality programming blah blah blah"

It is frustrating. I charge $5 more than everyone else for FT and $10 more for PT. My prices did turn away a lot of potential clients but I did manage to fill my spots, just took some extra time. I kept thinking that this is how I want to run my program, this is what I want to offer, I deserve to be fairly compensated AND want parents who appreciate what I am offering. I don't want clients who think I charge too much ~ they are the ones who don't care what I offer. I want parents who appreciate my hard work and I also think we DO deserve to make a living just like anyone else. Venting with you I guess.

I really don't have any concrete advice other than keep playing up what makes you stand apart and above the competition. Play up the quality of food you are offering, your experience, your reliability, etc. Those that care will notice.
