Oh, how awful for you! I never have interviews during daycare hours. It is way too hard to keep then kids busy while trying to focus on the new parent. Of course the kids act up....when a parent arrives it signals home time, even if its not their parent! What if you had initial interviews in the evening, then if they seem like a good fit, you could try a daytime playdate if they really wanted to? None of my clients has ever seen the daycare in action before placing their child.
