If you can afford to keep them keep them on. Another option is if they want to keep their part-time spot then they do a rate increase. I am going through another issue too, all caused by Bill 10. I promised a family I would never increase rates and then Bill 10 happened and BAM. Now I have to tell them I have to increase their rates by 5 dollars a day and I;m so nervous. I had a spot open for 4 months bc all the responses I'm getting is for infants. Ultimately you need to do whats best for you and your family bc all these other families look out for their own, we come second. You and your family come first so do what you need to do to make a living
