M.B.
If you know a lot of people who live nearby or work nearby with those hours then you'll do well. You might want to charge a little bit more for toddlers. The reason daycare centers change prices as children get older is because the ratios go up and you have more children per teacher. Home daycares don't change ratios, so you don't have to reduce price for toddlers. You also will need to provide food for toddlers which means more cost for you.
You might want to join an association to help you get started and for moral support. It's the hardest job you'll ever love and it's great to meet with others from time to time.
Best of luck to you!
