Thank you again girls for all your wonderful replies. My DH called FDC head office and they basically said, unless it's a regular visitor to the property, then there are no guidelines. That doesn't make me feel any better at all! I chose FDC over child care, because I thought he'd do better with a one on one environment and the he'd get the same person each time he went. But, now I feel like I've got no way of protecting him. Will have to have a long think and a big discussion with DH over the weekend.
