Once you give special it rarely works out to take it back.
My advice would be to advertise and replace each family, one at a time.
Yes, You can give them a choice to follow your new policies or be replaced, but that has it's own issues as well.
It typically reverts to them demanding special and using your income as an ultimatum once you turn prospective clients away.
This leads to stress, stress leads to resentment, resentment leads to burnout, burnout leads to closing of daycare (sometimes involuntarily). Same cycle, never ending.
Once you have new clients, do not give exceptions. Period.
Do not make policies you will not enforce.
