S.G.
i wouldn't pay by the hour i'd pay by the week. where i'm from day care for an infant is actually almost so expensive it's pointless to work running at almost 200 a week, but for children it's an average of 50-70 during school and 90 during summer vacation (per week). I'd negotiate a cost with your babsitter, maybe she can agree to go cheap for you to keep you as a "client".
