I don't think that it is your price or the fact that you use environmental cleaners (many people will find this a plus, some won't care one way or another, then there will be a few who think it's a bad thing...you can't please everyone). You just need to hang in there. Do you have a website? That has been my biggest plus since I opened. How about business cards? Do you have any playgroups or moms groups you could attend and give out your business cards? How about a local caregivers group that you could attend? Otherwise, Kijiji, Daycare Bear and any other advertising you have available to you. On another note, have a look at your set-up, your space, what you are offering in general and make sure it isn't these things that are keeping people away. Good luck!
