First, if you are getting inquiries and scheduling interviews that's a good first step. You have to fine tune your interviewing skills with your new methods of running your business. Are you in a large city or a small town? It sounds like you used to 'babysit'? Is that correct? But now you want to run a daycare and follow all the rules of the Day Nurseries Act and be a real business woman.
Don't throw away your contract, please! You deserve to be treated fairly and you need to attract the kind of families who respect that fact. I consider myself to be very informal, yet I keep a schedule for the children and have definite rules that must be observed by all parents and children and I expect my contract to be followed to the letter.
It's really difficult to get started. You have to get that first client to prove that you are doing a good job to get more clients and that's hard sometimes. Do you have a plan for your daily routines, activities you can do inside and outside the house, food and naptime plans, teaching plans and all the rest ready to go? If so, go over all of that in your interviews and describe how you will run your daycare.
Don't give up, you will find the right families. It took me a while but now I know what kind of families I want and what kind I don't want and I am comfortable during interviews now. Sometimes rejection still stings and then right around the corner will arrive the perfect clients. Be patient, and above all else, don't be desperate, be confident. I'm sending you all the luck I can.
