I do interviews during daycare time, I always have a few over the phone and make sure these people are truly committed and interested.....then I have them come during a "downtime" in the day....free play about 10 to 11 works great...that way I have time to spend with the parents and the parents have a chance to see things in action, see the children, the house and myself interact with the children, I really feel that is important and every time I have met with parents they have always had positive comments regarding the way I interact and the good behavior of the children....that being said, IF I had a child who had questionable behavior for what ever reason, I would def make sure that child was not present for the first interview, can give parents mixed ideas.
