Daycare centres are not cheaper in my area, obviously if a person qualifies for subsidy (and it's not a private centre that doesn't accept subsidy) then the cost is less and the difference in money is a huge reason to switch but I find the majority who want centre care want it for the consistency, no concerns over providers sick days or time off for vacations. Regardless of their preference over one or the other, if a person doesn't have back up care or flexibility in their job to take time off then this would be a good reason to go with a centre.
