Does the guardian have conditions that prevent her from picking up on time? Or is she taking her time getting to the center?

If the parent is continually late I would explain the severity involved with all parties. Their child is probably sad to be the last to leave and is very excited when seeing their parent at the end of the day. This also affects the child care workers by having to stay late when they also have things going on after work. I would probably ask to talk with her and state that pick up time was 20 minutes ago and ask if she has responsibilities causing her to be late. I might make a suggestion like leaving 20 minutes early so that she can get there in time. I would want to get my point across without being over powering so I think that I would let the parent talk then give my suggestions.
