Kidlove here. I am the same as judy and crayola, I charge for a sick day as well, in my contracts I require 24 hours notice for days off. Therefore if someone wants to pull a last minute, or if their child really is sick, which are both unpredictable...I still get pd. I also have a minumum due each week, which also helps to protect my income. If someones child is ill and they call me the pm before or in the am of days care, they are fully aware they must pay for that day, IF they need a second day off due to illness, that is always "uncharged".....but. .the minimum due is still in effect. Win, Win for me.
