I agree. I have operated my home child care for 15 years and have consistently told the parents to drop by (except for sleep time). In all these years, only 2 families took me up on the offer. A lot of problems can be avoided if parents are willing to utilize this opportunity. They should not feel like intruders, but should also understand the point above...if you let your child see you, he/she is yours to take home. It can take a long, long time to re-settle a child so be discreet!
