If you're concerned about her seeing your ad up after you've turned her down, you could do what I do. I always tell people that I like to maintain a wait list so I almost always have my ad up. I'm always meeting with people. I have one client who wanted to meet with me 6 months ago for a spot this september. Ridiculous amount of time! But I met with her with the assumption I wouldn't have space. Someone got pregnant and took a mat leave, someone else is doing the same, so here I am with a space coming up exactly when they need me. And because I took the time to meet with that client they are happy to take on that space when it comes up.

Honesty is always the best. We service our communities. Often someone knows someone and if you're caught in a lie it may come back to bite ya later.

Going forward make sure you mention in your interviews that it's you interviewing them as well, and you need to make sure the child and the parents are a good match for you since you work so closely together. That always gives me an out if I need to turn someone down.
