I go on about my day. I personally don't mind what time they are dropped off but I do mind if they are late at pick up. I just started my daycare and my first little one started two weeks ago. The first 2 full days they were late (5min and then 25 minutes) I sent them an email on the Friday reminding them that my pick up time is 5:00. I told them that I trust they were able to adjust to their new schedule this week and that as of Monday, any late pick-up will be charged a late pick-up fee as outlined in the agreement. If late drop off bothers you definitely put your foot down. As I outline in my guidelines, I have a family of my own and have a schedule so these times are important to be respected.
