I have my open/close hours but that's not what I go by everyday. Technically, I will open at 6 if someone needs to be at work by 6:30 but...if the first scheduled child is to arrive at 7 then I don't open my door until 7. They sure as heck wouldn't get up early if they didn't have to so why do they expect us too? I have had to deal with this a few times. I had a parent show up at 6:15 and weren't supposed to be there until 7. They sat outside in the rain as I was in the shower and had no idea they were there until I got out and checked my phone (they texted from the driveway!). I have sent out countless emails and reminders that if they are going to change their drop off or pick up time they have to let me know in advance. It usually only takes once of sitting outside for them to 'get it!' My rates are the same regardless of the amount of hours used each day so its not like they can complain about not getting their money's worth lol
