I wish I could say that I've never experienced a no call/no show in my home daycare career but I have in the past, I also have had tons who arrive late and expect me to be right there waiting for them.

Because of having tons of experience with this I have a fairly strict late/no show policy. I have drop off time from 7:30 - 8. If you aren't here by 8 I continue with our plans. That means if they are late with no notice than they have to find us and meet us where we are, if they are unable to find us or meet us then the parent is responsible for finding and paying for alternate childcare. To this day, I still have 1 parent who is late almost every day.
