I always schedule after hours. I explain to the prospective clients that this is largely because no one I don't know comes into my home during daycare hours unless it's a scheduled maintenance/repair person who can show me a company id. In my experience parents really appreciate and respect that I'm taking that step to protect the children. Honestly, anyone can answer an internet ad... I also agree that it's too hard to focus on answering questions while my attention is divided. I also let potentials know though that after that initial interview (re I've screened them ) they are welcome to come for a second short visit to see us in action. Then they know that I've got nothing to hide!!!
