Exciting....good luck!!
I'm a bit like Lee Bee, I have super casual interviews. They come down to my daycare and have a little look around. Then we usually just sit on the floor and chat. My girls run around playing and their child wanders around checking everything out.
I don't show anyone my contract. I go over the basics but we really just have more of a "get to know you" chat. I always ask what they are looking for in a daycare. At they end I just thank them for coming, nice to meet you kind of thing!
I am insanely fussy and can tell within a few minutes if I would ever work with people. I do let parents know that I am doing lots of interviews and leave it up to them to get back to me if they are interested.
Good luck tonight, I hope they are both awesome and you get your spots filled!!
