Be careful not to waste your time interviewing parents who are just shopping around. We don't need to waste our precious evenings when we work such long hard days. I learned that the hard way and do a very thorough pre-screening now. If the parents really want centre care but just want to look around at home daycares you will figure that out quickly. If they love the idea of one on one care at a home daycare and close friends and less sickness and a homey atmosphere instead of a school type setting you can find that out.
