You charge for the set weekdays only that the child is enrolled.
Fees will depend on what your area "norm" is and what your experience/qualifications are. If you are an RECE or offer a unique program(ie. organic food/montessori/ 2nd language teaching/have outside instructors in(ie gymnastics/music/yoga etc) then you might get more. If you are in Ontario, the "2 under 2" laws limit your enrollment, so many charge more for that age group. Do a mock search for daycare using your postal code on the daycarebear search engine, and you'll see what's out there in your area.
