Okay just some thoughts.....
1. If you are unable to fill your places with even one client at $45, why do you believe you will be able to get one in and charge more by calling yourself a Nanny instead? Surely if the clients aren't there, the clients aren't there?
2. If you realize that organic food and a natural lifestyle might be hindering your ability to attract new clients, why are you not changing your business model? If these are important to you, please understand that new clients might not share your enthusiasm - do they perhaps think your prices reflect the specialist service and therefore if it's not important to them are they loathe to pay what they deem a premium for a service that doesn't matter? I wonder if you simply dropped the information about this and remained the same price, if clients would be more interested? Are you firmly committed on this or flexible enough to drop it entirely and perhaps then be able to drop your fees a little and appeal to a wider audience?
3. Does your soap business have the opportunities you need to work FT and get the income you require? Or can you get what you need working fewer hours? Do pros and cons in writing, I find that sometimes helps.
4. Since it seems you are doing both at the moment, why not step up the soap business until you have clients for the day care?
Which business do you enjoy the most? And is just one a viable option financially?
