Some people seem to forget that their child's daycare is still the provider's home.

For myself I tell my parents to just come in. That is only because my daycare is in my basement and I do not want to be running up and down answering the door. I have one family who will knock before coming in. My doorbell doesn't ring downstairs so I wouldn't hear it anyways. The one thing that really annoys me is if I am standing at the bottom of the stairs when the parent comes down and they will go and sit on the couch with their child. Ummmm.....NO. I am standing and meeting you at the entrance to daycare so that you take your child and go home, not get comfy and make yourself at home.
