Okay! Well, thank you for explaining. That makes a ton more sense! Now that I have all that information it sounds like she was not completely cut out to be a special needs provider. Not everyone can do it. I don't think she handled the termination right, and don't think you should need to pay. I know that if any providers have families that mention leaving (not necessarily threats-perhaps not the best choice of words on my part), they look for replacements right away. They don't want that fear hanging over their heads; not knowing if it was going to come. If she was aware to the point that there was a diagnosis, a special diet, and receiving special compensation for this extra care, that's a horse of another color. It sounds like you just outgrew each other and she found she wasn't cut out for it with a larger number of kids in care. I wouldn't pay those two weeks as she was not willing to provide services for them. I am in Alberta too.
Glad your son is now in a place he is thriving in.
