FunnyFarm...this sounds like an overprotective parent or one with zero insight into reality. When/how does he expect you to go to the bathroom? Hold it for 10hrs? If he wants full supervision than he needs to enroll his child into a Centre not a Dayhome. This is common sense.
Coming from a parent...not a daycare owner, shake this one off. Sounds like your dcd lives on a different planet.
