Yes, I try to plan things way in advance! I have a walk in clinic my Dr. runs that I can go to at night if I need meds for something. I plan my annual stuff months in advance and let the parents know as soon as I know. I have a friend that can come and watch one or 2 so i give 1 or 2 the option, but I also have parents with great backup close by. So, they usually just keep their kids home.

I believe anything can be done if you have a good plan!
