Look up daycares on this site that are close to you (you can put in your postal code and it will bring them up within a certain radius) and see what they are charging. It also depends on if you offer meals/snacks - most do, but some charge less and have parents supply food.

I charge more for infants under 2, as they require more "hands-on" care, with diapers, feeding, etc.

Also look on kjiji. A lot of providers don't post their rates on kijiji ads, because the rate varies due to age, number of hours, meals, etc, but some do, so that might give you a ballpark.

Good luck!
