Looks like I am the odd man out here.... Kids under one ARE a higher fee, for me. Not by much, it's only a 50 dollar per month difference. Children that age are more physically demanding, in my mind. They need to be fed by my hand often, picked up/ lifted/ carried more, need more diaper changes, and so on. Ages one to 10 are the same fee.
I am interested in the idea of implementing higher fees for using the entire 10 hours though. I like that idea. I know for a fact that I have parents who wait until 5:27 to pick up, because "they pay for it".
