I agree with the other two post. I offer partime care but they have to guarantee min 20 hours per week. That way you can have some stability and it gives the family some freedom to have flexible care. You could ask her to commit to a certain number of days and if she can't than you can say she can stay on till your able to fill the spot with a full time child. I know its not nice but at the same time you have to do what is right financial for you and your buisness. After all that is the nice thing about running your own buisness you can do what works for you.
